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 building 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 its beginnings, this path has been built on the study of Japanese tradition, ongoing training, research, teaching and outreach, in 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.

That gaze toward the territory led me naturally to bonsai and suiseki. Not as isolated hobbies, but as cultural expressions capable of condensing the essence of nature on a human scale. Since then, I have devoted decades to the study of these disciplines, delving into both their technical practice and their historical, philosophical and aesthetic foundations.

Before the master's tokonoma

My training has been closely tied to Japanese tradition, especially through learning alongside masters and professionals who have helped shape my understanding of this art. However, my goal has never been to reproduce models mechanically, but to understand the principles that underpin them in order to transmit them authentically within our own cultural context.

The concept of Keidō — the Way of the Landscape — sums up much of that search. A way of understanding bonsai, suiseki and their related arts not as isolated objects, but as tools for contemplating, interpreting and expressing the natural environment.

This space was created as a place for rigorous study, documentation and transmission. A place to share the experiences, research and work accumulated over the past decades. Teaching and practicing bonsai and suiseki are understood here as a path of exchange, learning and cultural preservation. If you have arrived here moved by the same curiosity, perhaps we share part of the same path.

There are paths that 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.
Journey

The Path

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

From this point on, the journey is presented in documentary and 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

Began his activity 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 systematic monitoring of birdlife, collaborating with SEO/BirdLife on the study and monitoring of bird populations.

He later worked as an ornithologist for the Department of the Environment of the Generalitat Valenciana, carrying out research studies on endangered species endorsed by the Spanish National Research Council (CSIC).

From the age of fifteen, he was actively involved with Acció Ecologista-Agró, a pioneering organization and benchmark in nature conservation in Spain. Within this organization he took part in numerous study, protection and conservation campaigns, notably his involvement over several years in reforestation programs in the Valencian mountains affected by the fires of the 1980s and 1990s, contributing to the recovery of large areas of what is now the Sierra Calderona Natural Park through the planting of native species such as holm oak (Quercus ilex).

The ongoing research into birdlife at La Marjal dels Moros, together with the compilation of species inventories and the drafting of technical reports (studies on biology, ecology, habitat selection and conservation) to present its value to regional, national and European authorities, generated the scientific basis used in the case for the wetland's protection. This documentation proved decisive in the process that culminated in its designation as a Wildlife Refuge by the Generalitat Valenciana.

Studies in Physical Geography

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 reading of 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. Thus began a professional, full-time dedication to bonsai that, over the years, would extend to suiseki, as well as to Kazari and Keidō, disciplines in which these elements take on their full artistic dimension.

Distance study with Kobayashi Ippū

Began a personalized, direct course of study in Keidō under the guidance of the III Iemoto of the Katayama School, an unprecedented arrangement for the school. In the summer of 2024 he received his Japanese name, a Gō (号) or "path name": 勝讓武古 (Masaru Buko), calligraphed by the master's own hand, in recognition of natori status.

Transmission at the Shunkaen Museum

His second in-person stay at the Shunkaen Museum (Tokyo) will take place.

He will formally receive the makimono — the lineage scroll certifying 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 will mark the first complete journey of this kind documented and certified for a Western bonsai and suiseki specialist.

景道片山流

The Lineage

This transmission is not an isolated gesture: it is part of a precise system of rules and meanings that has, generation after generation, governed how 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 where 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, treating 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 spiritual dimension.

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

KanjiMeaning
Katsu To win, to overcome — victory without force.
Yuzuru To yield, humility — the spirit of victory yielded.
Bu Martial, inner peace — a kanji of mission: transforming bonsai from the ornamental into a path of rectitude.
Ko Ancient, seniority — 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 genealogical belonging. The ceremony is scheduled for October 2026, during the second in-person stay at the Shunkaen Museum.

Nature of the affiliation

Formal membership in the Keidō Katayama-ryū lineage with full ceremonial legitimacy. This affiliation does not imply succession rights to the position of Iemoto, nor institutional authority within the school's Japanese structure. Sagunt-En carries out its bonsai and suiseki teaching activity independently, inspired by the principles and teachings transmitted by this lineage.

The Path of the Lineage

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

Respect Humility Patience Letting go of the ego

I had the good fortune of being received as a disciple under the guidance of Kobayashi Ippū. 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 up a world of sensitivity and spirituality for me: a space where what I saw transformed into what I am.

The Oku no Kyomatsu is no longer alive. 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 he connected with most, the one that made him reconsider the entire course of his life.

During my study stay in autumn 2025, with respect, honor and humility, I wanted to express my gratitude toward my master and toward his beloved tree. I brought a watercolor painted by hand by my friend and fellow disciple, the Bolivian artist William Garcés, depicting the pine in all its splendor, when it was still alive.

Nothing in that gesture was improvised. For months we prepared every detail: the choice of the image, the artistic composition, the presentation ceremony. The work traveled wrapped in a furoshiki, as Japanese tradition dictates for acts of gratitude, and was offered with both hands, between an opening bow and a closing bow, in absolute silence.

Alongside the watercolor, I prepared a card written in Japanese and headed with that same symbol, to record my gratitude toward the master, toward the tree that inspired his path, and toward the teaching he has generously offered me over these years. What we love does not disappear: it transforms and endures, in memory and in practice.

Philosophy

If Bonsaidō and Suisekidō represent the path of refinement through the tree and the stone, Keidō is the natural culmination of that process. Within it, bonsai, suiseki and the other elements that traditionally accompany them are no longer seen as isolated objects, but become 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 are 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 component speaks with the others. What until then might be perceived as an outstanding example of specialized horticulture or a valuable collector's piece takes on 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 emotion held within each composition: the art of harmonizing elements to express, through them, the deep relationship between human beings and nature.

Much of the bonsai practiced today in the West has drifted toward the commercial and the competitive, moving away from that foundation. This is not to deny the value of that path — many fine trees are born there too — 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 an 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 origin.

The direction chosen here does not arise from an aesthetic preference or a professional strategy, but from a deep conviction: to truly understand bonsai and suiseki, one must approach the cultural, philosophical and spiritual roots that gave rise to them.

Throughout their history, these disciplines did not emerge as forms of entertainment, as objects of consumption, or as means of gaining personal recognition. They were born from a particular way of observing nature, from a sensibility developed over centuries, and from a constant search for harmony between human beings and landscape.

For this reason, the study of bonsai and suiseki cannot be reduced solely to technical matters, superficial aesthetic criteria, or the pursuit of visually striking results. Behind every tree and every stone lies a much broader cultural tradition, bound up with contemplation, patient observation, respect for the passage of time, and the ability to discover beauty in what remains simple, natural and authentic.

The influence of Zen thought and other traditional Japanese aesthetic currents can be felt in many of the principles that shaped these disciplines. This is not about reproducing a religious doctrine, but about understanding an attitude toward nature based on attentiveness, simplicity, humility and direct experience.

Over the years, especially outside Japan, many different ways of approaching these disciplines have emerged. Some emphasize competition, others exhibition, others the market or the pursuit of quick results. All of them are part of a diverse and legitimate reality. However, the path proposed here is different.

The main interest does not lie in seeking awards, recognition or standing within an industry, but in the study, understanding and transmission of principles preserved across generations. The priority is not to produce more trees or gather more stones, but to develop a way of seeing capable of understanding what made the birth of these traditions possible.

When these disciplines become completely detached from their cultural roots, they risk losing part of their original meaning. Keeping that connection to the source alive does not mean rejecting evolution or ignoring contemporary contributions, but constantly remembering where they came from and what their original purpose was.

That pursuit of depth, authenticity and fidelity to traditional principles is the foundation of this project, and the reason a path centered on study, transmission and the contemplation of nature has been chosen above any other consideration.

Matsuo Bashō 松尾芭蕉

No name is cited more often among practitioners of Keidō than that of Matsuo Bashō (松尾芭蕉, 1644–1694). He was no gardener and never grew bonsai, but his travel poetry —the haiku (俳句) as a brief form of contemplating landscape and the seasons— is, for this school, the purest literary expression of the same impulse that Keidō pursues through the tree, the stone and the display space.

Bashō left the city to walk the land, stripping his gaze down until only the essence of the landscape remained. That same renunciation of the superfluous is what governs composition in Keidō.

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

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

Traditional School of Bonsai and Suiseki Art

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

At our school we understand bonsai and suiseki as artistic and cultural expressions deeply connected to the contemplation of nature, to Japanese aesthetic sensibility and to 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 art, observation, harmony and the cultivation of an eye capable of recognizing the essential beauty of the landscape.

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

Our school is a space for those who wish to deepen, research and understand 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 along a living tradition.

We believe that bonsai and suiseki are not merely objects for contemplation, but vehicles for understanding nature, time, landscape and our relationship with them.

This is the path we follow. This is the spirit we transmit.

Two itineraries, one same path

Two training itineraries conceived for those who wish to deepen their understanding of bonsai from an artistic, cultural and traditional perspective, integrating technique, aesthetics and Japanese thought into a single learning process. Training is offered both in person and online, with students from Spain and countries across Europe and the Americas.

In-person training in Spain is specifically oriented toward those who wish to approach the artistic level represented by the Kokufu-Ten, from a rigorous, aesthetic perspective deeply rooted in Japanese tradition.


First level
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 aluminium: 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 Seiya 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.

  • 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 Completing the Advanced Course is recommended to make full use of the Master's program, although both levels can be taken independently depending on the student's prior experience. Both conclude with an assessment of the content covered and the corresponding diploma. Given its higher level, the Master's program is certified with a master's diploma issued by the Sagunt-En School.

Would you like to start this training path? Each student follows a different path. Training adapts to their level, goals and prior experience, while always maintaining the same standard: understanding bonsai as an artistic and cultural discipline, not merely as a cultivation technique.

After a question from me, he stopped, turned to the room and pointed at me: he said, with great conviction, that I was his student, that I had come to study at his Shunkaen museum, and that I had already been two years on the path alongside him. He then explained to the Japanese and international audience the importance of Keidō — the exact moment when bonsai stops being technique and becomes art.
