Introduction

Who Am I?

In quiet contemplation, Japan

My name is Marcial Yuste Blasco, though within the path of bonsai and suiseki I am known by my Japanese transmission name, Masaru Buko (勝讓武古).

My journey did not begin in a pot or an exhibition hall. It began much earlier, in the study and observation of landscape. Trained in Physical Geography and deeply connected to the natural world, I have devoted much of my life to roaming mountains, wetlands, and natural spaces, learning to interpret the forms, processes, and silences that give a territory its character.

There are different ways of pursuing a path in bonsai and suiseki. Some are oriented toward participation in competitions and competitive exhibitions; others find their expression in study, research, teaching, and the transmission of knowledge. The path recorded on this page deliberately follows this latter orientation.

From the outset, this path has been founded on the study of Japanese tradition, ongoing training, research, teaching, and outreach, founded on the conviction that knowledge, sustained practice, and respect for the artistic and cultural legacy to which bonsai and suiseki belong form the foundation of a lasting dedication to these disciplines.

Some paths begin long before we learn to walk them. Sometimes, life quietly sows what, with the years, will end up defining us: hands stained with soil, terraces overflowing with flowers, endless summers in the mountains, and the curious gaze of a child who dreamed of discovering the wild world.

Only much later did I understand that my love for nature had begun long before I could put a name to it. This video is a journey back to that origin.

Before the Path

Long before bonsai and suiseki became part of my life, another question had already accompanied me for years: how human beings related to the natural world before we stopped considering ourselves part of it.

My interest in nature was never limited to observing it. I was also deeply interested in understanding human beings within it. For that reason, prehistory and human evolution occupied an essential place in my studies and preoccupations for many years. I was especially drawn to societies that predated agriculture, when survival depended directly on knowledge of the land, its cycles, its animals, its plants, its water, and its seasons.

Over the years I have gathered pieces and reproductions related to that history: African bifaces, stone tools, and museum-quality replicas of skulls belonging to different stages of human evolution. I have never understood them merely as archaeological objects. To me they represent the testimony of a human being who still lived immersed in the landscape and whose existence depended on understanding it.

Over time, that interest extended to other cultures and ways of thinking in which nature does not appear as a setting separate from human beings, but as part of a reality of which they themselves are part.

I found a particular affinity with the Indigenous cultures of North America and their profound relationship with the land. Beyond the differences among peoples and traditions, I was drawn to a worldview in which the earth, water, animals, plants, and places hold meaning beyond their immediate use — a way of understanding the world grounded, in many cases, in belonging, reciprocity, and respect for that which makes life possible.

Among the readings that left a particular mark on my thinking was the well-known speech attributed to Chief Seattle. Regardless of the historical controversies surrounding the various versions that have come down to us, those words expressed an idea I recognized as deeply close to my own: the impossibility of separating human beings from the land that sustains them.

My words are like the stars: they never go out.

That intuition has stayed with me ever since.

That is also why, when I later discovered certain Japanese traditions, I did not feel I was encountering an entirely new idea. Rather, I found another way of expressing a relationship with nature that human beings have sought and developed in many different ways throughout their history.

Shinto, Buddhism, the art of landscape, the contemplation of the seasons, and, later, the traditions associated with bonsai, suiseki, and the Japanese contemplative space offered me a particularly precise language for expressing something I had long been seeking.

Provenance
Former private collection of Ramona Kühnel (biface.de), German in origin, North Africa / Sahara.
Acquisition
Specialized private trade, 2000s.

And perhaps that is precisely why bonsai, suiseki, and Keidō came to hold, for me, a meaning that goes far beyond technique or aesthetics. In them I found a way of once again situating human beings before the landscape — not as owners, but as observers, interpreters, and part of it.

The path I walk today began long before I could give it a name.

Japan was not the origin of my way of looking at nature.
It was one of the places where that way of looking found a language.

Journey

The Path

From observing nature in the wild to the formal study of the Japanese art of display. A single calling sustained for more than four decades.

From this point onward, the journey is presented in a documentary, chronological format, with the aim of preserving the historical accuracy of events, research carried out and institutional milestones reached over the years.

Naturalist, ornithologist, and nature conservationist

He began his work as a naturalist at the age of thirteen at the Wildlife Refuge of La Marjal dels Moros, a wetland of international importance. There he began the systematic monitoring of birdlife, collaborating with SEO/BirdLife on the study and monitoring of bird populations.

Studies in Physical Geography

He studied Physical Geography at the Universitat de València, focusing on Geomorphology and Analytical Climatology. This training deepened his understanding of the natural environment, natural processes, and the interpretation of the landscape—a foundation that later directly influenced his approach to bonsai and suiseki as arts that evoke the natural landscape.

More than 23 years

Bonsai as a discipline

His passion for nature merged with an interest in traditional Japanese culture. This marked the beginning of a full-time professional dedication to bonsai that, over the years, would extend to suiseki, as well as to Kazari and Keidō, disciplines in which these arts attain their fullest artistic expression.

Transmission at the Shunkaen Museum

His second in-person study stay at the Shunkaen Bonsai Museum in Tokyo is scheduled to take place.

He is scheduled to formally receive the makimono—the lineage scroll certifying his inclusion in the keizu, or living genealogy of the school, with the rain kanji (雨) as its genealogical trunk—and the kakejiku bearing the transmission name Ichibu (一武), to be received through ichiji-hairyō.

This milestone is expected to mark the first documented and certified journey of its kind completed by a Western specialist in bonsai and suiseki.

景道片山流

The Lineage

This transmission is not an isolated act: it is part of a precise system of rules and meanings that has, generation after generation, governed the way a master recognizes a disciple.

Keidō is the Japanese art of composing the traditional display space within the Katayama-ryū lineage, in which bonsai, suiseki, kakejiku, and accompanying elements are arranged in relation to the tokonoma, the contemplative alcove of sukiya-style Japanese architecture.

The tokonoma, developed within the Japanese architectural tradition and especially established since the Muromachi period (室町時代, 1336–1573), is the space in which nature is presented as an object of contemplation.

Founded in 1986 by Katayama Teiichi (片山貞一, 1908–1996), this system transcends any purely ornamental or horticultural function, understanding each composition as an evocation of the seasons and a means of contemplating nature.

Inspired by the principles of Sen no Rikyū’s tea ceremony (千利休, 1522–1591), Katayama developed an interpretation of wabi-sabi (侘寂) applied to the display space, where simplicity and imperfection take on a spiritual dimension.

The name 勝讓武古 (Masaru Buko) is not a phonetic transcription. It was created by Jin Yasufumi, guardian of the lineage, as an ethico-semantic transliteration of the name Marcial Yuste Blasco, with each kanji chosen both for its phonetic value and for its ethical meaning:

KanjiMeaning
Masaru To win, to overcome—victory without force.
no phonetic function To yield, humility—contributes no sound; incorporated solely for its symbolic weight.
Bu Martial; inner peace—a kanji of mission: transforming bonsai from an ornamental art into a path of integrity.
Ko Ancient, venerable—the depth gained with time.

The makimono will bear the kanji 雨 (Ame), the genealogical trunk of the school since its founder, and the kakejiku will carry the transmission name 一武 (Ichibu), to be received through ichiji-hairyō: the act by which the master grants the disciple a character from his own name as a seal of lineage affiliation. The ceremony is scheduled to take place in October 2026, during the second in-person study stay at the Shunkaen Bonsai Museum in Tokyo.

Why is 勝讓武古 read Masaru Buko?

At first glance, the writing 勝讓武古 raises an inevitable question: how do these four kanji arrive at Masaru Buko, if the name’s pronunciation isn’t simply obtained by applying the characters’ usual readings? The answer lies in the very process by which the name was created.

From sound

As Jin Yasufumi, guardian of the lineage, explained, the starting point was my name, Marcial Blasco, whose pronunciation was adapted into Japanese as まさるぶこ (Masaru Buko). Japanese characters were then assigned to this pronunciation, giving written form to a pronunciation of alphabetic origin. First the sound was established; only then was a script sought that could give it meaning.

To meaning

But the choice of characters didn’t respond only to a phonetic question. 勝讓武古 was also constructed for the meaning its four kanji were meant to express together: yielding victory and carrying the spirit of 武 to its fullest maturity, through time and tradition.

勝ちを讓り、武を古くなるまで極める。 — Jin Yasufumi
Pronunciation ≠ writing

Here lies the name’s particularity: pronunciation and writing follow different paths. Masaru Buko is the established pronunciation; 勝讓武古 is the written form conferred upon it and, at the same time, the conceptual construction that expresses its meaning. The sound identifies the name; the kanji add what the name is meant to express. The pronunciation says what one is called; the writing, in turn, makes it possible to express why one is called that.

Function of the kanji

The four characters don’t function as a simple phonetic transcription. 勝 contributes Masaru, 武 contributes Bu, and 古 contributes Ko, while 讓 carries no phonetic function and is incorporated for its meaning: to yield, to renounce victory, to act with humility. Its phonetic silence doesn’t make it secondary—it is precisely the character that introduces one of the composition’s fundamental concepts.

The result is a deliberate construction in which spelling, pronunciation, and meaning don’t maintain a mechanical correspondence. The pronunciation comes from the Japanese adaptation of the name; the kanji, in turn, give it a second dimension: an idea that couldn’t be expressed by writing the sound alone. It isn’t a matter of finding kanji that say how a name sounds, but of finding kanji also capable of saying what it means.

The Path of the Lineage

Some encounters shape a path. My master, Kobayashi Ippū, while contemplating the Japanese white pine Oku no Kyomatsu (奥の巨松), felt the calling that would lead him to devote his entire life to bonsai. That tree became his silent guide—a presence that still speaks with the patience of time and the stillness of centuries.

Bamboo sumi-e

I had the privilege of being accepted as a disciple under Kobayashi Ippū’s guidance. I learned to listen to the whisper of each branch, to feel the patience in each cut, to recognize humility in each shoot and impermanence in each form. His teaching opened a world of sensitivity and spirituality to me: a space where what I saw transformed into what I am.

The Oku no Kyomatsu no longer lives. The master keeps it in his personal shrine at Shunkaen, where he pays it respect and offers incense—not as a relic, but as the totemic presence of the tree with which he felt the deepest connection, the tree that led him to reconsider the course of his entire life.

Philosophy

If Bonsaidō and Suisekidō represent the path of self-cultivation through the tree and the stone, Keidō is the natural culmination of that process. Within Keidō, bonsai, suiseki, and the other elements that traditionally accompany them are no longer seen as isolated objects, but are integrated into a harmonious composition imbued with meaning, emotion, and aesthetic depth.

Bonsai and suiseki, understood through Japanese tradition, are neither decorative horticulture nor a collection of stylistic techniques. They constitute a path of contemplation: the evocation of landscape and the seasons as a way toward inner stillness.

Through the correct arrangement of the main elements, complemented by the kakejiku (掛軸), accent plants or shitakusa (下草), and the various accompanying objects such as tenpai (添配), a space of contemplation is created in which each element enters into dialogue with the others. What until then might be perceived as an outstanding example of specialized horticulture or a valuable collector’s piece acquires a higher dimension, becoming a true artistic expression.

Keidō does not seek merely to display beautiful objects, but to reveal the atmosphere, the season, the landscape, the passage of time, and the quiet emotion contained within each composition: the art of harmonizing elements to express, through them, the deep relationship between human beings and nature.

Much of contemporary bonsai practice in the West has drifted toward commercialism and competition, moving away from that foundation. This is not to deny the value of that path—many fine trees emerge from that tradition as well—but to point out that another path exists, older and more demanding, which the Sagunt-En School seeks to uphold: that of bonsai and suiseki as the art of space, faithful to classical Japanese principles.

That is the underlying vocation of this work: not to compete within an industry, but to preserve and pass on a way of understanding the tree, the stone and the space as close as possible to its origins.

The Path of Suiseki

A landscape held in stillness.

The stone does not change before us. It is we who, by sitting beside it long enough, learn to stay still.

Among the traditional Japanese arts, perhaps none is as silent as suiseki.

At first glance, nothing seems to happen. There are no branches growing, no flowers appearing with the arrival of spring, nor leaves announcing autumn.

The stone remains motionless, indifferent to the haste of the world. Yet the longer one remains beside it, the more evident it becomes that this silence is full of meaning.

Suiseki is usually defined as the art of appreciating natural stones capable of evoking landscapes, mountains, islands, waterfalls, or other forms suggested by nature.

The definition is correct, but it barely manages to express what suiseki truly represents. To define it is to limit it, and suiseki, by its very nature, resists any boundary that tries to enclose it completely.

A suiseki stone is not created.
It is not carved.
It is not modified.
It is not corrected.
It is found.
And that distinction changes everything.

While many artistic disciplines begin with a creative gesture, suiseki begins with an act of recognition. The work already exists.

No landscape is painted onto the stone.
One learns to see it within.
The artist’s hand does not intervene.
Only the eye intervenes.
Nothing is added.
Nothing is taken away.
Nothing is invented.
Only recognized.
Only accepted.

It has been shaped over millions of years by water, wind, ice, and the slow passing of geological time. Every crack, every fold, is the trace of forces that no longer exist. Human beings add no beauty to the stone; they learn to discover the beauty that was always there.

That is why searching for a suiseki has never been simply a matter of searching for stones.

Mountain-landscape suiseki with a chain of connected ridges, on a wooden daiza · Marcial Yuste Blasco’s collection
A very natural, evocative mountain landscape · personal collection

One searches for landscapes.
One searches for horizons.
One searches for mountains that fit between two hands.

Every river, every coast, and every path holds countless stones. Only a few awaken an image without imposing it.

The collector does not decide what the stone represents. It is the stone itself that, slowly and patiently, reveals what it had always kept hidden for centuries.

In the Japanese tradition there is a specific word for this particular discovery: mitate (見立て). It does not mean imagining something arbitrarily, but rather learning to recognize a reality that was already suggested by another.

Mitate does not invent the landscape.
It reveals it.
It does not impose a form.
It discovers it.
It adds nothing foreign.
It invents no story.
It only names what was already there.

A stone stops being merely a stone when it also becomes a mountain wrapped in mist, or a waterfall suspended just before touching the water.

What is truly fascinating is that nothing has changed.
The stone remains exactly the same.
What has changed is the gaze.

There are stones that spend years on a shelf saying nothing. One day, under a different light or after long contemplation, they reveal a landscape that was always present.

It did not appear suddenly; our sensitivity simply learned to recognize it. That inner transformation is one of the deepest teachings of suiseki.

The mountain does not impose itself.
It offers itself to those who know how to look.
It does not seek to be seen.
Nor does it avoid it.
It waits,
unhurried,
for its own recognition.

Contemplation does not change what we observe.
It changes us.

Standing before a bonsai, we come to perceive the time of living beings. Before a suiseki, we perceive the time of the Earth itself.

The tree grows slowly.
The stone, by contrast, seems motionless.
One breathes in years.
The other, in ages.
One changes before our eyes.
The other changes without our ever seeing it.

But that stillness is only apparent. Each of its forms is the result of processes so prolonged that they overflow the scale of a human life.

Where we count years, the stone has known millennia. Where we speak of generations, it remembers vanished mountains and seas that no longer exist. What for us is history is, for the stone, barely an instant; what for us is memory, for it is an ongoing present; what for us is ancient, for it is still young.

What for us is history,
for the stone is barely an instant.
What for us is memory,
for it is an ongoing present.
What for us is ancient,
for it is still young.

To contemplate a suiseki is to accept, with serenity and without resistance, the quiet, fleeting smallness of human time before the eternal stone.

And far from being unsettling, that awareness produces a strange peace.

We understand that not everything needs to happen quickly.
That there are rhythms far older than our worries.
That nature has never felt urgency to reach its fullness.

Perhaps that is why suiseki holds such a close bond with Zen: not because it represents a religious doctrine, but because it invites an attention free of haste. To remain before a stone may look like stillness; inwardly, something quite different happens. No technique teaches how to reach it, only time and disposition. Whoever sits before a stone without hurry ends up, sooner or later, listening to their own silence.

Silence and permanence · personal collection

The mind begins to settle.
Thoughts lose their intensity.
The body, without meaning to, slows its pace.

The constant need to interpret and name things gives way to a simpler contemplation.
Little by little, the silence of the stone finds an echo in the silence of the observer.

At that moment there is no longer a clear distance between the one who contemplates and that which is contemplated. Only the experience of being present remains.

That state of stillness does not stay confined to the observer: it naturally seeks a place to manifest itself.

This contemplation finds a privileged place in the tokonoma, where a suiseki converses with a bonsai or a kakemono. None seeks to impose itself over the others.

Nothing competes to be seen.
Each object awaits its turn in the silence.
Each element yields space to the next.
Nothing claims the centre for itself.
Everything needs the space that surrounds it.

That space is a manifestation of ma (間). In the Japanese tradition, emptiness never represents a lack. It is the place where beauty can breathe.

The distance between the stone and the hanging scroll, or the serene silence that fully envelops a room of contemplation, holds as much importance as the objects themselves. Without that subtle, necessary margin of air, neither the stone nor the scroll could breathe.

When everything is full,
nothing can truly be seen.
Emptiness does not interrupt the landscape.
It completes it.
It does not impoverish it.
It sustains it.
It makes it possible.
It imposes nothing.
It simply allows.

The ages of the mountain · personal collection

In the same way, suiseki partakes of the ancient principle of shakkei (借景), "borrowed scenery." A carefully presented stone does not enclose a landscape; it opens it. It allows a room to extend, imaginatively, toward distant mountain ranges, solitary coasts, or valleys wrapped in mist. The small ceases to be a limit and begins to suggest the immense.

That capacity for suggestion also belongs to the realm of yūgen (幽玄), what is intuited but never exhausted by the gaze.

What is truly profound never shows itself completely.
An excellent stone always keeps part of its mystery.
It does not answer every question.
It does not immediately reveal everything it holds.

It invites the observer to return again and again, discovering new landscapes as the light, the season, or the observer’s own inner state changes. No visit exhausts what the stone has to show.

With time we come to understand that suiseki does not teach us to look at stones.
It teaches us to look at the world.
After many years of practice, a mountain ceases to be only a mountain.
A river ceases to be only a river.

Even a rock forgotten at the edge of a path may hold a beauty that once went unnoticed.

Contemplation changes the way we inhabit nature.
It makes us more attentive.
More patient.
More receptive.
More humble.

Perhaps that is why suiseki needs so few words: its language is another one, made of time and of silence.

The stone does not try to convince.
It proves nothing.
It demands no attention.
It simply remains.

A mountain range held within a stone · personal collection

And in an age dominated by a vertiginous way of life, immediacy, and noise, that permanence stands as a teaching of extraordinary relevance.

Perhaps that is precisely why more and more people today seek in suiseki something that everyday life no longer seems to offer: a fixed point from which to look at the world.

We live surrounded by objects designed to be replaced.
The stone proposes exactly the opposite.
To remain.
To wait.

To accept the passage of time without resistance.
To remember that true depth never arises from haste.

When bonsai and suiseki are presented together, side by side, in the same tokonoma, they establish a silent and profound dialogue between two very different ways of understanding and inhabiting nature, between life and permanence.

That dialogue seeks no victor: it seeks, simply, a balance. It is not about choosing between the tree and the stone, but about learning to hold both presences without either eclipsing the other. In that coexistence, perhaps, the deepest meaning of the tokonoma reveals itself.

The tree speaks of growth, and of life that changes.
The stone speaks of permanence, and of time that transcends generations.
One represents movement.
The other, stillness.
One slowly transforms living matter.
The other preserves the memory of a transformation already past.
Both speak, in the end, of the same silence.

And yet, both lead toward the same teaching.
To contemplate without desiring to possess.
To accompany nature without imposing our will upon it.

The stone never asks us to understand it.
It only invites us to sit beside it long enough.
We are the ones who, in the end, have changed.

A reference

Matsuo Bashō 松尾芭蕉

No figure is more frequently cited by practitioners of Keidō than Matsuo Bashō (松尾芭蕉, 1644–1694). He was neither a gardener nor a bonsai artist, but his travel haiku (俳句)—a concise poetic form devoted to the contemplation of landscape and the changing seasons—is, for this school, the purest literary expression of the same spirit that Keidō seeks to express through the tree, the stone, and the display space.

Bashō left the city to journey through the landscape, paring his gaze down until only the essence of the landscape remained. That same rejection of the superfluous lies at the heart of composition in Keidō.

furu ike ya kawazu tobikomu mizu no oto An old pond—/ a frog jumps in; / the sound of water.

松尾芭蕉, c. 1686—a constant source of inspiration for those who follow the Way of the Landscape.

World Bonsai University

Instructor at World Bonsai University

Teaching as part of the path itself

World Bonsai University (WBU) logo

World Bonsai University (WBU) is a private online training platform devoted entirely to bonsai. It emerged to fill a gap that, for years, existed in the Spanish-speaking bonsai world: the absence of a structured, progressive, and accessible distance-learning offer, in a field where knowledge had mostly been passed on in person and in fragmented ways. It is worth stating this plainly: WBU is not a university in the academic or official sense of the word, nor does it hold government or institutional recognition comparable to that of a regulated institution of higher education. It is a private entity, and, at present, the only one offering a catalogue of this breadth and continuity devoted entirely to teaching bonsai.

The platform brings together a small group of internationally recognized instructors, each responsible for their own catalogue of courses. Training is organized through recorded video lessons and PDF materials, structured by level—from beginner to advanced design—with exams and completion diplomas for the courses that include them. Alongside this recorded content, the platform offers live videoconference classes and, occasionally, in-person workshops, combining independent study with real-time guidance.

Teaching on the Platform

I have been part of WBU’s instructor team since 2021, with a catalogue centered on bonsai design and aesthetics—the area where I identified the greatest gap in Spanish-language training—and on Keidō and Kazari, the art of correctly displaying a bonsai or suiseki. Over these years, that dedication has resulted in one of the most extensive course catalogues among the instructors who take part in the platform, something I mention not as an achievement in itself, but as a reflection of the time and study behind each course.

Courses I Teach at WBU

  • The first module of the design trilogy, built to establish the classical rules of composition, the vocabulary of the craft, and how to read the fundamental forms of bonsai. It lays the theoretical foundation the following two modules build on.
  • A natural continuation of Module 1, going deeper into compositional balance, the rhythm between mass and empty space, and the dynamism of the apex as the element that guides the tree’s visual reading.
  • An expanded version of the previous modules, with monthly live tutorials to work through questions on students’ own trees. It adds a detailed study of the classical styles and the particularities of design in juniper and Sabina.
  • The most complete of the design courses, with dozens of hours of content that integrate and expand on everything covered in the previous levels into a single, unified body of design theory.
  • The largest existing compendium on the correct display of bonsai according to Japanese tradition: single-element compositions, three-element compositions, and those of five or more, along with the terminology and criteria governing each.
  • A live session focused on branch formation and refinement in deciduous species: pruning, pinching, and defoliation applied with judgment, beyond the mechanical technique itself.
  • A second live session, this time devoted to the Pinus genus: how to develop branching according to each pine group’s behavior, how to trigger back-budding, and how to balance vigor using mekiri, metsumi, and other specific techniques.
  • A live session on the physiological fundamentals behind every intervention on the tree: photosynthesis, carbohydrate reserves, and vigor cycles across the year. It explains how to design a fertilizing program consistent with each species’ phenology, rather than following generic schedules that ignore the tree’s actual energy state. The goal is for the student to decide when to intervene and when to wait, based on physiology rather than the calendar.
  • A class focused on species prized for their flowers and fruit, a group that requires adjusting pruning, pinching, and defoliation so as not to compromise those phases. It covers the right timing for intervention according to each species’ flowering cycle, and the fertilizing strategies that favor flower and fruit without weakening the tree. It also includes design criteria for not sacrificing bloom for the sake of silhouette.
  • A monograph on the wild olive (Olea europaea var. sylvestris), one of the most widely collected Mediterranean yamadori species in Spain, with behavior of its own that is rarely explained in detail. It covers its particular cultivation, repotting, and healing requirements, along with the design criteria best suited to its character. Aimed at those working, or wanting to work, with native Mediterranean material.
  • A session devoted to the highest-risk techniques in the craft: major limb removal, forced bends, complex approach grafts, and other interventions that seriously threaten the tree’s survival if carried out without judgment. It explains the protocols that let material be pushed to its limit without losing it, and when taking that risk is justified. Intended for those who already master the basic technique and want to expand their range of action.
  • A class that treats cultivation not as an end in itself but as a design tool: how sound agronomic management directly determines which stylistic transformations are possible and which are not. It explains the relationship between vigor, branch density, and the tree’s capacity to respond to design interventions. A perspective that integrates agronomy and aesthetics into a single working criterion.
  • A session on the two fundamental techniques for modifying a tree’s structure when pruning alone is not enough: layering, to obtain nebari or new material, and grafting, to introduce branches or correct design shortcomings. It details the different types of each technique, the optimal timing by species, and the aftercare required to ensure success.
  • A class devoted to correctly collecting material from the wild: how to assess a specimen before collection, which root and substrate protocols increase the odds of survival, and how to manage the first months of aftercare following collection. It also covers the ethical and legal criteria that must be respected in this practice.
  • A live session in the personalized mentoring program, in which students present their own trees for a real-time design assessment. It covers structural decisions, choice of front, branch management, and stylistic coherence on a case-by-case basis. The format lets the theoretical criteria from the courses be applied to concrete, real design problems.
  • A continuation of the personalized mentoring program, once again focused on individual reviews of trees brought in by students. It builds on themes already introduced in the previous session—choice of front, mass balance, apex management—applying them to new material and to more complex cases. It serves as a natural continuation of the live mentoring cycle.
  • A session devoted to the classical styles of Japanese tradition—chokkan, moyogi, shakan, kengai, among others—and the formal criteria that define each one beyond its name. It explains how to identify the style best suited to a given piece of material and how to avoid the most common compositional mistakes when forcing a tree into a style that does not fit it.

A Path That Never Ends

Holding an extensive catalogue on the platform is not, for me, an end in itself. 道—Dō, the path—is precisely that: a path that is never fully walked, however far one has already come. Teaching does not exempt me from continuing to study; if anything, it demands more rigor from me. That is why I have taken, almost in their entirety, the courses published by WBU’s other instructors, not as a symbolic gesture but as one more way of remaining a student, even while my role there is that of an instructor. In October 2021, WBU itself recognized that path with a Certificate of Honor and Excellence, after the completion of fifty courses by other instructors, each passed with the highest grade.

Certificate of Honor and Excellence awarded by World Bonsai University to Marcial Yuste Blasco

That double condition—student and instructor at once—was acknowledged separately a few months later. In June 2022, WBU issued a distinct Certificate of Recognition, this time for my work on the other side of the classroom: for the collaboration and dedication behind teaching bonsai of high quality within the platform. Read together, the two certificates trace the same movement described above—continuing to learn while already teaching—recognized first as a student, then as an instructor.

Traditional School of Bonsai and Suiseki

gi ni hajimari, bi ni itaru One begins with technique; one reaches beauty.
Kūkan Yūbi Where there is space, there is beauty.
Keisō Daishō Small in size, great in presence.

At the Sagunt-En School, we understand bonsai and suiseki as artistic and cultural expressions deeply rooted in the contemplation of nature, Japanese aesthetic sensibility, and a tradition passed down across generations.

Technical knowledge is part of the path, but not its destination. The true purpose of bonsai and suiseki transcends technique to enter the realm of artistic expression, observation, harmony, and the cultivation of an eye capable of recognizing the essential beauty of the landscape.

Our teaching is grounded in the rigorous study of traditional Japanese sources and in continued study within the classical systems of Japanese cultural transmission. For this reason, learning is not limited to the care of a tree or the appreciation of a stone; it also embraces an understanding of the aesthetic, philosophical, and cultural principles that gave rise to these arts.

The Sagunt-En School is a place for those who wish to deepen their knowledge, pursue research, and gain a fuller understanding of bonsai and suiseki from a broader and more authentic perspective. A place to cultivate patience, sharpen observation, develop one’s own aesthetic judgment and walk with respect within a living tradition.

We believe that bonsai and suiseki are not merely objects of contemplation, but vehicles through which we come to understand nature, time, the landscape, and our place within it.

This is the path we have chosen. This is the spirit we seek to pass on.

Advanced Bonsai Art Course
Online · 15 topics · with exam and diploma
  • Container cultivation imposes physiological constraints that have nothing to do with garden or ornamental plant growing: limited root volume, precise water management and constant vigor control. The topic covers the specific needs of the tree in a pot—reading water demand by species, vegetative state and environmental conditions; water quality and pH; physical-chemical properties of bonsai substrates; correcting nutritional deficiencies; fertilizing programs using solid organic, liquid organic and chemical fertilizers—as well as proper placement of specimens, species selection suited to each climate and arrangement on display benches. The aim is to master the three or four fundamental guidelines that determine 95% of cultivation success, with special attention to managing residual moisture, the main cause of bonsai pathologies.
  • Direct intervention techniques applied to the tree, studied from both agronomic and artistic standpoints. Structural and refinement pruning; selective pinching for growth control; partial and full defoliation—purpose, timing, and candidate species. Wiring with copper and aluminum: theoretical application model, execution, correct tension by branch thickness, timing, and precautions to avoid marks. Repotting: optimum timing by species, root treatment and pruning, substrate reduction or replacement, correct anchoring of the tree in the pot and post-repotting care. Identification of the main bonsai pests and diseases; types of plant protection products (systemic and contact); preventive and curative treatment strategies, with examples of common pathologies and action protocols.
  • The five classical styles—classified according to the degree of trunk inclination from vertical—are not taxonomic categories but formal models reproducing at reduced scale the shapes trees take in nature in response to their growing conditions: climate, exposure, altitude, species. This topic explores in depth the design principles of each style: reading trunk movement, branch distribution, nebari construction and apex projection. Understanding the basis of each form is the first step toward designing a bonsai with visual and botanical coherence.
  • Applying the same criteria as the previous topic, this unit explores in depth the remaining styles recognized by Japanese tradition—those which, though less common in exhibition contexts, are often the most appropriate expression for a starting material with distinctive morphological characteristics. Knowing them and being able to read when the tree calls for them is as important as mastering the canonical styles. The choice of style is not a personal preference, but a response to the form latent within the tree’s own structure.
  • Reproducing the forms of natural trees to scale is a necessary condition, but not a sufficient one: a tree may be correctly designed and still lack aesthetic power. Elevating a bonsai to the artistic dimension requires mastering a set of concepts that act directly on the viewer’s visual perception. In this topic—the most dense and fundamental of the five aesthetic topics in the course—the principles that make a bonsai visually powerful are studied: dynamic balance, management of negative space, and asymmetry as a tool for naturalness and age. The difference between specialized horticulture and bonsai art lies precisely in mastering these elements.
  • This topic expands on theoretical concepts that, due to their complexity, could not be incorporated in the previous topic without compromising its density. It also includes an extensive practical section of visual analysis of specific specimens: the student learns to read how aesthetic elements articulate, interrelate, and reinforce one another in a real tree. Visual understanding of aesthetics—seeing in the tree what was previously only understood theoretically—is the qualitative leap this topic aims to consolidate.
  • Development of aesthetic concepts at a higher degree of abstraction which, precisely because of this, are capable of refining design to levels that more obvious principles cannot reach. This topic continues and deepens the line of the previous one: new ideas, new analytical angles and new specimens to consolidate an increasingly refined and autonomous aesthetic vision. The aim is for the student to begin developing their own personal standard, derived not from imitation but from genuine understanding.
  • A monographic topic on Seya Takeshi, one of the great Japanese masters—and one of the least known outside Japan—who conducted an exhaustive, systematic, and descriptive analysis of the factors that determine the beauty of a bonsai. His research led him to identify three fundamental axes: dynamic balance, which in trees that possess it generates greater visual attraction; the management of negative space, understood not as absence but as an active element of the composition; and asymmetry as an instrument for conveying naturalness and age, qualities that trees acquire in nature under the influence of the elements and adversity. Mastery of these three principles defines the difference between a well-formed tree and a bonsai that speaks.
  • Consolidation and extension of the concepts developed in previous topics through comparative visual analysis of a wide selection of trees. The student trains their eye to identify with precision the elements that raise—or limit—the aesthetic dimension of each specimen, developing their own critical vocabulary that allows them to analyze, correct, and project their own designs from understanding rather than intuition.
  • Development of the highest-abstraction aesthetic concepts: those which, precisely because they are not immediately visible or easily codified, have the power to elevate design to levels that more direct principles cannot reach. New ideas, new analytical angles and new reference specimens to continue refining the eye and consolidating an increasingly autonomous aesthetic vision. The aim is for the student to be able to perceive, name, and apply elements of beauty that they previously only felt without knowing how to articulate.
  • A complete treatise on the art of kazari at every level: tokonoma composition principles, hierarchy, and relationship between elements (bonsai, suiseki, kakejiku, shitakusa, tenpai), seasonal reading, compositional formality according to the shin-gyō-sō system and the aesthetic criteria at the foundations of Kazari. Kazari is not decoration: it is the art of creating a space that invites contemplation and conveys the spirit of a season and a moment.
  • Expansion of the concepts and ideas from the previous topic, with detailed analysis of real kazari compositions. The student studies how the various elements articulate in specific situations, what decisions make them more or less successful, and what formal, chromatic, and seasonal relationships between them determine the quality of the composition. The aim is to develop the ability to read and build a kazari composition with autonomy and sound judgment.
  • The Kokufu-Ten is the highest reference in Japanese bonsai. This topic works on the practical application of all the concepts learned—in the two style design topics and the five aesthetics topics—through detailed analysis of exhibition specimens. The student learns to read a Kokufu-Ten bonsai by precisely identifying the elements that determine its artistic level: design, proportion, nebari, branching, species character and aesthetic dimension. This practice of analysis is the most direct route to consolidating and refining everything learned.
  • Continuation of Kokufu-Ten specimen analysis with new trees and compositions. The work of topics 13 and 14 on the Kokufu-Ten is the equivalent of what in classical Japanese arts is called kata: the repeated and intentional practice on reference models to internalize principles until they become one’s own. Both topics together form the closing stage of the course and direct preparation for the final evaluation session.
  • A two-hour online session with the teacher, both evaluative and formative in character. The student is presented with photographs of Kokufu-Ten bonsai and kazari compositions to analyze orally at the level of design and aesthetics. The teacher evaluates not to grade, but to identify what has been solidly absorbed, what is mastered but not yet precisely articulated and what points require reinforcement. Based on that reading, they correct, refine, expand, and work with the student on what is still unseen or unclearly expressed. It is a guided review class, a synthesis and consolidation of the entire course.

Would you like to begin this path of study? Each student follows an individual path. The program adapts to each student’s level, goals, and prior experience, while always maintaining the same guiding principle: understanding bonsai as an artistic and cultural discipline, rather than merely a cultivation technique.

  • It is not possible to work on a tree without understanding how it functions. This topic begins with plant physiology as applied to bonsai: tree anatomy, how the vascular system works, seasonal cycles and the response to water and mechanical stress. The concept of energy occupies a central place: where and how the tree produces it, how it moves it and how it manages it. Without that knowledge, any pruning, pinching or defoliation is blind, because all of them directly affect the tree’s ability to generate and manage its reserves. Fertilizing is studied as a precision tool in the service of controlled vigor: types of fertilizers (solid organic, liquid, and mineral), dosage, schedule, and adaptation according to species, vegetative state and cultivation goal.
  • At master’s level, the study of pests, diseases, and plant-protection products goes beyond basic identification. The topic delves into the classification of the main pathogens and vectors affecting bonsai, their life cycles, favorable development conditions and differential diagnostic symptoms. It covers the different types of plant-protection products—systemic, contact, preventive, and curative—their mechanisms of action, compatibilities, and limitations, as well as the criteria for designing an integrated protection program that preserves the health of the tree, the quality of the substrate and the surrounding growing environment.
  • A complete monograph on the most highly valued and demanding plant group in Japanese tradition. It examines in depth the specific physiology of potted conifers, their cultivation needs, repotting timing and criteria, fertilizing programs and particular shaping and refinement techniques: metsumi, mekiri, mekaki, hagari, and their variants by species. It also covers branch construction in pines, junipers, and cypresses, with specific criteria for each group, and the aesthetic reading of their distinctive formal qualities. Conifers have their own language: learning it is a condition for being able to work them with rigor.
  • Deciduous trees demand very precise technical mastery because their four seasons are always on display: the nebari and trunk in winter, the unfolding of foliage in spring, the canopy in summer and the autumn color. The topic thoroughly covers pruning, wiring, pinching, and defoliation techniques, with special attention to developing and refining ramification according to the vigor of each species: differentiated techniques for species of strong and moderate vigor, alternate-leaved and opposite-leaved species, and specific criteria for the deciduous trees most referenced in Japanese tradition—maple, elm, hornbeam, zelkova, among others. Building a fine, balanced, and aesthetically coherent branch structure is the central goal of this topic.
  • Evergreen and tropical species display physiological behavior different from that of deciduous trees and temperate-climate conifers, which requires adapting all cultivation criteria and working techniques. The topic examines how to modify repotting, fertilizing, watering, and vigor-management programs for this group of species, and how to coherently apply shaping and refinement techniques to material that has no marked winter dormancy or that responds differently to pruning stress. The aim is to broaden the student’s technical repertoire beyond the classical Japanese groups and equip them with the criteria needed to work rigorously on any species.
  • Flowering and fruiting species are enjoyed precisely for their blossoms and fruit, which imposes a particular technical logic: many of the usual pruning, pinching, and defoliation operations must be adjusted or reoriented so as not to compromise those physiological phases. The topic covers the specific cultivation and management criteria for this group, the appropriate timing of intervention according to each species’ flowering cycle, and the shaping strategies that allow a strong aesthetic design to be built without sacrificing flowering or fruit set. Flowering and fruiting bonsai are also among the most direct expressions of the passing of the seasons.
  • Two long-form video modules—around three hours each—devoted entirely to the aesthetic analysis of Kokufu-Ten trees. The teacher analyzes in depth a selection of reference specimens, identifying and explaining how the aesthetic principles studied throughout the course manifest in each tree: design, proportion, species character, dynamic balance, management of space and the qualities of the nebari and branching. This sustained visual analysis is the most effective way to internalize aesthetic concepts and begin seeing them in one’s own trees.
  • Two video modules of between two and three hours devoted to the analysis of kazari compositions. The teacher breaks down real compositions—from the Kokufu-Ten and other benchmark exhibition contexts—explaining in detail the decisions that shape them: the relationship between the main bonsai and the accompanying elements, seasonal reading, the formality of the composition, the visual dialogue between objects and the selection criteria specific to Kazari. The aim is for the student to understand how a high-level kazari composition is built and to begin developing their own with independent judgment.
  • The pot is not a container—it is part of the work. This monograph covers everything needed to choose the right pot for each bonsai: shapes—rectangular, oval, round, hexagonal—glazed and unglazed finishes, colors, textures, proportions, foot and rim details, and the characteristics that define the character and formality of each piece. It also examines the criteria for the formal relationship between tree and pot—shibui—that allow the choice of container to enhance the tree’s beauty rather than compete with it. The student learns to read a pot and to decide with well-founded aesthetic judgment.
  • A monograph on the most demanding and visually striking techniques in Japanese tradition: jin, shari, sabamiki, tanuki, and other interventions of high technical and aesthetic complexity. Each one is studied in depth: rationale, criteria for application, execution, aftercare, and aesthetic reading. These techniques are not decorative devices: they are tools for expressing the passage of time, the tree’s struggle with the elements, the memory of the landscape. Applied without judgment they look artificial; applied with rigor, they give a compromised or difficult tree an artistic dimension that no other technique can achieve.
Training Path and Diploma Completion of the Advanced Course is recommended in order to fully benefit from the Master’s Program, although both levels may be undertaken independently according to each student’s prior experience. Both conclude with an assessment of the material studied and the awarding of the corresponding diploma. Due to its advanced level, the Master’s Program is certified through a Master’s Diploma issued by the Sagunt-En School.

Rokkon Shōjō (六根清浄)

Speaker, exhibition guide, and master of ceremonies for the official program

Rokkon Shōjō—a Buddhist expression referring to the purification of the six senses—brought together bonsai, suiseki, ikebana, chadō, shodō, sumi-e, and traditional music and dance under a single program at CEART. Unlike the competitive exhibitions usual in bonsai, the gathering was conceived without prizes or classifications, as a unified showcase of traditional Japanese culture.

Participation

Invited by the organizers as a speaker for the official program, I led the guided visit to the bonsai and suiseki exhibition on the opening day, presenting to the public the historical, aesthetic, and philosophical foundations of both disciplines—empty space, wabi-sabi, and respect for nature.

I also served as master of ceremonies, presenting and conducting the program’s events, coordinating the panel discussions, and introducing the visiting Japanese artists.

An Unrepeatable Spirit

I know of no other gathering in Spain that has brought together such a concentration of Japanese masters and traditional disciplines within a single program. It was precisely that breadth—bonsai, suiseki, ikebana, chadō, shodō, sumi-e, music, and dance sharing the same space without hierarchy among them—that made Rokkon Shōjō an exceptional gathering.

No prizes, no competitions, no classifications: throughout the weekend, Japan was experienced in its purest form, with the Zen spirit as the sole common thread. Rarely, outside Japan, have I felt so deeply connected with that spirit.

After a question from me, he stopped, turned toward the audience, and pointed at me. He stated with great conviction that I was his student, that I had come to study at his Shunkaen Museum, and that I had already spent two years walking the path alongside him. He then explained to the Japanese and international audience the importance of Keidō—the moment when bonsai transcends technique and becomes art.

Bird watching, the Mediterranean landscape, suiseki, bonsai, and Keidō are not separate stages of one life, but different ways of approaching the same reality: the contemplation of nature.

Keidō Katayama-ryū  ·  The Way of the Landscape

Lineage Transmission One Life,
One Path
Madrid  ·  Tokyo  ·  Shunkaen

2022–2026

Four years ago I began a path that seemed unattainable:
studying Keidō under Kobayashi Kunio, III iemoto of the
Keidō Katayama-ryū school—a venerated master in Japan,
the foremost reference in contemporary bonsai.

He accepted me.

2022—First stage

I studied remotely for a year and a half, in a format without precedent.
On completing that cycle, I received my first diploma,
signed and sealed by the iemoto.

2024—Conferral of the natori

The guardian of the lineage granted me my art name:

勝讓武古 Masaru Buko

A name built with profound philosophical intent.
No one in the West had ever received a natori from this school.

2025—Residency at Shunkaen, Tokyo

I traveled to Tokyo for an in-person residency of study and evaluation.
On its completion, the iemoto hand-calligraphed my second diploma:
more than sixty kanji personally brushed,
numbered No. 1 among all his Western disciples.

2026—Formal lineage transmission (expected)

I will return to Shunkaen to receive the school’s official transmission:
a kakejiku bearing the kanji that will inscribe me into the school’s living genealogy,
and a makimono that will certify my place on that tree forever.

勝ちを讓り、武を古く極める Yield the victory; perfect the art into seniority.
This is not an ending. It is the true beginning of the path.
