An organization of international reference

There are institutions whose prestige is not born solely of their antiquity, but of the constancy with which they have preserved and transmitted a cultural legacy over time. In the field of bonsai, Bonsai Clubs International (BCI) has occupied a place of reference within the international community for more than six decades.

Founded in 1963, BCI emerged with a purpose as simple as it was ambitious: to build bridges between individuals, clubs, and institutions from different countries united by the same passion for bonsai. In an era when access to knowledge was limited and international exchange was far more complex than it is today, the organization understood that the preservation of these disciplines depended, above all, on the willingness to share them.

Since then, BCI has promoted international conventions, specialized publications, educational programs, exhibitions, and cooperative projects that have established a permanent dialogue among Japanese masters, artists, researchers, collectors, and enthusiasts across all continents. Thanks to this continuous effort, entire generations have been able to discover not only the specific techniques of bonsai, but also the deep cultural background from which this discipline originates.

However, reducing the importance of BCI to its organizational activity would be insufficient. Its true contribution has consisted in enabling a tradition born in the East to take root with respect in very different cultures, always maintaining a delicate balance between fidelity to its roots and the natural evolution that every artistic expression experiences when it crosses borders.

This transmission has never depended exclusively on trees, stones, or cultivation techniques. It has depended, above all, on people. On those who dedicated countless hours to teaching, researching, writing, organizing gatherings, preparing exhibitions, and accompanying new generations of enthusiasts so that knowledge would not be interrupted. In this sense, BCI has acted for decades as a great international community united by a common goal: to preserve a cultural heritage whose authentic richness resides in being shared.

Perhaps that is why speaking of bonsai also means speaking of time.

Not only of the time a tree needs to mature or the centuries that water takes to shape a stone, but also of the human time dedicated to learning, teaching, and transmitting that which one received from those who came before. Every tradition survives thanks to this silent chain of masters and disciples, of researchers and educators, of people who understand that knowledge only remains alive when it continues to move from one pair of hands to another.

In Japanese culture, there is a profound awareness that no work endures on its own. It needs to be cared for, understood, and transmitted generation after generation. Bonsai participates fully in this vision: it is an art of contemplation, but also of continuity. Each cultivated tree and each appreciated stone is part of a conversation begun long before us and destined to continue when we are no longer here.

It is precisely within this spirit of continuity that Bonsai Clubs International develops one of its most significant educational and professional projects: the International Instructors Program, conceived to recognize those who have dedicated a significant part of their lives to the study, teaching, and dissemination of these disciplines, helping to keep alive an artistic and cultural legacy that transcends generations.

The International Instructors Program

Every tradition needs masters. Not only individuals capable of executing a technique with precision, but people willing to dedicate a part of their lives to understanding, preserving, and transmitting it with fidelity. In traditional Japanese arts, teaching has never consisted solely of explaining procedures; it involves transmitting a way of observing, an attitude toward learning, and a specific relationship with time.

With this same philosophy, Bonsai Clubs International created the International Instructors Program, an initiative designed to recognize professionals whose trajectories reflect a significant contribution to the development, teaching, and dissemination of bonsai on an international level.

Far from defining the instructor as a mere technical specialist, the program recognizes a dedication sustained over time. The accumulated experience in cultivation, research, teaching, dissemination, publications, exhibitions, or collaboration with clubs and institutions constitutes, as a whole, the true foundation of this accreditation.

Being an instructor implies accepting a responsibility that goes far beyond teaching courses. It means becoming a link in a chain of transmission that began long before our generation and that will continue thanks to the commitment of those who today assume the task of sharing what they have learned. In a way, knowledge never belongs completely to the one who possesses it; it always remains on loan until it finds new hands capable of preserving and enriching it.

This idea is particularly close to Japanese sensitivity. Traditional teaching does not aim solely to train competent technicians, but to cultivate a way of seeing. Authentic learning begins when technique ceases to be an end in itself and becomes a means to understand nature, the passing of the seasons, and the silent dialogue between the human being and that which is contemplated on a deeper level.

For this reason, the International Instructors Program does not evaluate practical knowledge alone. It recognizes trajectories built over years through constancy, research, and the willingness to share experiences with an increasingly diverse international community. Teaching, lecturing, writing specialized publications, participating in conventions, organizing exhibitions, or advising clubs are all part of the same vocation of service toward the art of bonsai.

The transmission of knowledge also constitutes one of the pillars upon which Japanese culture has historically developed. Many traditional schools use the word keiko (稽古) to describe learning. Although it is usually translated simply as "practice," its original meaning invites us to look toward the past to understand those who preceded us. To practice is, in a way, to converse with previous generations through what they left behind as a legacy.

From this perspective, teaching does not mean placing oneself above the student, but walking a few steps ahead to illuminate a path that others will continue to travel. Each generation receives an incomplete knowledge and has the responsibility to transmit it slightly richer than how they found it.

BCI materializes this philosophy through an international network of instructors spread across numerous countries, creating a space for collaboration where individual experience is put at the service of a much broader community. This diversity enriches the program, allowing different cultural traditions to converse without losing deep respect for the Japanese roots of both disciplines.

Official Registry of Instructors As part of this commitment, BCI maintains an officially published Registry of Instructors: more than a simple record of accredited professionals, it constitutes a meeting point between those who wish to learn and those who have dedicated a significant part of their lives to teaching bonsai.

However, the true value of this directory does not lie solely in gathering names or credentials. It represents an international community united by the same conviction: that knowledge only remains alive when it is shared with generosity, with rigor, and with respect for those who will one day continue to transmit it.

In the Japanese tradition, there is a particularly meaningful word: kokoro (心). It is usually translated as "heart," although its meaning is much broader, as it unites heart, mind, and spirit into a single reality. No teaching fully achieves its purpose when it is limited to transmitting information; it must also transmit kokoro. Technique can be learned in a few years. Sensitivity requires a lifetime.

Perhaps that is the true raison d'être of the International Instructors Program. It does not limit itself to recognizing knowledge accumulated over decades. Above all, it recognizes a permanent commitment to a way of understanding bonsai as a living cultural discipline, whose continuity depends on the generosity of those who accept the task of teaching so that others may keep learning.

My admission to the Program

Every distinction acquires its true meaning when it becomes a starting point and not a destination.

In July 2026 I was admitted to the International Instructors Program of Bonsai Clubs International, joining its Official Registry of Instructors as an Instructor of Bonsai.

I received this appointment with profound gratitude and, at the same time, with a serene awareness of the responsibility it entails. Rather than a culmination, I understood it as an invitation to continue a path begun many years ago, when curiosity for small trees grown in pots began to transform, slowly, into a way of understanding nature and relating to it.

Every trajectory dedicated to bonsai is built through countless hours of observation, study, and practice. There is knowledge that can be acquired from books or during a course; other insights only appear after many years of living alongside trees, stones, and the passing of the seasons. These are silent teachings, impossible to rush, which only time grants to those who accept to learn with patience.

Over more than two decades, I have sought to develop this learning from different angles: continuous study, research, teaching, lecturing, specialized publications, exhibitions, and cultural dissemination. Each of these activities has constituted a different way of bringing bonsai closer to people with highly diverse interests, experiences, and sensibilities.

However, I have always endeavored to ensure that the transmission of knowledge was not limited to teaching specific techniques. Learning how to wire a branch, repot a tree, or appreciate a stone constitutes only a part of the path. It is more important to understand the relationship these disciplines establish with nature, with time, and with a way of looking at the world that finds an inexhaustible source of depth in simplicity.

With the passing of the years, I have come to understand that bonsai possesses the extraordinary capacity to gather very different cultures around the same silent language. A tree needs no translation. Neither does a stone capable of evoking a mountain, an island, or a waterfall. Contemplation is one of the most universal languages in existence, because it is born before words and remains when words are insufficient.

My work has aimed to develop precisely from this conviction: to contribute to building bridges between East and West, bringing Japanese tradition closer with the utmost respect for its roots and striving to transmit it in a rigorous, accessible, and faithful manner to its authentic cultural meaning.

This incorporation into the International Instructors Program represents, therefore, the recognition of a journey built with constancy, but also the beginning of a new stage. Every authentic distinction carries an implicit demand: to keep growing with the same humility with which learning began.

In the Japanese tradition, there is a principle that has quietly accompanied my way of understanding these disciplines: shoshin (初心), the "beginner's mind." Far from describing a lack of experience, it expresses the attitude of someone who, even after many years of practice, continues to approach knowledge with curiosity, respect, and a readiness to keep learning. Perhaps that is one of the most valuable lessons bonsai offers: the deeper one goes into it, the greater the awareness of all that still remains to be discovered.

Being part of BCI's Registry of Instructors means integrating into an international community of teachers united by the same commitment: to preserve, research, and transmit an artistic and cultural legacy that belongs to all those who care for it with respect. This membership constitutes an honor, but also a responsibility shared with those who, from very different parts of the world, dedicate their lives to keeping alive a tradition that continues to grow without losing the memory of its origins.

Looking back, I understand that no step on this path would have been possible without the generosity of masters, colleagues, and friends who shared their time, their knowledge, and their trust. All authentic teaching is, in reality, a received inheritance. No instructor can consider themselves the owner of the knowledge they transmit; they only have the privilege of safeguarding it for a time before placing it, once again, in the hands of those who will continue the path.

Therefore, this appointment does not represent a goal achieved, but a renewed commitment. I will continue to research, teach, and disseminate bonsai with the same respect that inspired my first steps, convinced that the best way to honor a tradition is to keep it alive, share it with generosity, and hand it over to the next generation slightly richer than how it was received.

The path of bonsai: a dialogue with time

A bonsai is not a miniature tree. It is time made visible.

Those who contemplate a bonsai for the first time usually focus on its dimensions. Those who return to contemplate it years later stop seeing its size and begin to perceive another reality: time.

There is nothing rushed about it. Each curve of the trunk, each branch, each empty space, and each scar tells a story written with a slowness that contemporary life scarcely remembers. A bonsai is not born as a work of art. It becomes one when the years deposit upon it a beauty that no human hand could manufacture on its own.

For this reason, bonsai is often defined as the art of growing miniature trees, although this description barely scratches the surface of what it truly represents. In essence, bonsai is a form of contemplation. It is a silent dialogue between the human being and nature, sustained over decades, in which both learn to listen to each other.

At the beginning of learning, it is easy to believe that we are the ones shaping the tree. We wire its branches, perform prunes, decide on the front, choose a pot. Everything seems to depend on our decisions. However, with the passing of the years, this perception begins to transform.

We then discover that the tree already knew its direction long before our hands touched it for the first time.

Our true task consists not in imposing a will upon it, but in recognizing the one that already dwells within it. Every intervention should look like a continuation of nature and not an interruption of it. The best work is, almost always, that which ceases to be perceived as work.

In the Japanese tradition, there is a profound admiration for that which seems to have emerged without effort. Not because it lacks labor, but because the labor has disappeared behind naturalness. This quality is called shizen (自然). An excellent bonsai never boasts of the skill of the one who cultivated it; it transmits the feeling that it was always thus, as if the wind, the snow, and the passage of years had shaped each of its movements on their own.

This naturalness cannot be improvised. It requires patience, observation and, above all, letting go. Relinquishing the temptation to intervene more than necessary constitutes one of the most difficult lessons of bonsai. The tree teaches us that, at times, caring means doing less, waiting more, and trusting in processes whose rhythm does not depend on us.

With time, we understand that the true master is not always the one holding the tools, but the tree itself.

Every spring, it buds without asking if the winter was too long. Every autumn, it lets its leaves fall without clinging to them. No season tries to prolong itself more than necessary. Nature knows no anxiety about remaining. It changes because changing is part of its balance. Bonsai participates fully in this cycle.

Spring awakens the force held during the winter; summer expands vitality; autumn invites letting go; winter returns the tree to the silence from which a new spring will be born. Year after year, season after season, the tree repeats the same cycle without ever repeating itself. Each budding is different. Each winter leaves a different mark. Permanence, paradoxically, is born of continuous change.

It is here where bonsai meets the Japanese sensitivity known as mono no aware (物の哀れ): the serene awareness that all beauty is inseparable from its ephemeral nature. The plum blossom moves us precisely because it will disappear. The red color of the maples touches us because the wind will eventually carry it away. Nothing loses value by being transient; on the contrary, it is precisely its transience that awakens our capacity for contemplation.

Alongside this awareness also appears wabi-sabi (侘寂), one of the deepest aesthetic ideas of Japan. Bonsai does not seek geometric perfection or absolute symmetry. Beauty arises from the trunk marked by the years, from a broken branch that continues to live, from bark cracked by the passage of time, from a scar the tree never tried to hide. The incomplete, the irregular, and the aged cease to be understood as defects and become the visible expression of an authentic existence.

In the West, we tend to admire that which remains pristine. The Japanese tradition, on the other hand, finds a deeper beauty in that which has aged with dignity. A bonsai does not try to hide time. It shows it with pride. Each mark constitutes the testimony of a storm overcome, of a winter resisted, of a spring that returned once more.

Perhaps that is why cultivating a bonsai is also an exercise in humility.

The tree grows at a speed oblivious to our expectations. It forces us to abandon haste and to accept that some answers only appear after many years. No technique allows us to accelerate the maturity of a trunk or manufacture the character that only time grants. Bonsai teaches us that there are achievements impossible to obtain through impatience.

In the Japanese tradition, there is another word that is rarely explained and yet is present in all great compositions: ma (間). It is frequently translated as "space" or "interval," though neither of those words manages to fully capture its meaning. Ma is the silence between two sounds, the emptiness between two branches, the air that surrounds the tree and allows it to breathe visually. It does not represent an absence, but a discrete presence. Thanks to the emptiness, the form acquires meaning. Thanks to the silence, contemplation finds a place to linger.

Bonsai also needs this space. Not everything must be filled with branches, foliage, or movement. The void allows us to imagine that which is not represented. A single isolated branch can suggest an entire forest. A small open space can contain the immensity of the sky. The imagination completes that which the tree barely hints at.

This capacity to suggest rather than show connects with another deeply Japanese concept: yūgen (幽玄), the beauty of that which remains partially hidden. A great bonsai never reveals everything at first glance. It invites the observer to return again and again, discovering new nuances as the light, the seasons, and the very experience of the one contemplating change.

Over the years, the tree ceases to be merely an object of observation and becomes a silent companion. Those who live for decades with the same bonsai end up associating each budding with a memory, each pruning with a stage of life, each repotting with a new beginning. The tree remains while we change. It grows slowly, almost imperceptibly, while our own lives unfold around it. Without intending to, it ends up becoming a witness to our existence.

There are bonsai trees that survive several generations. They pass from one hand to another without ceasing to grow. Each caretaker adds just a few years to a story much vaster than themselves. Understanding this deeply transforms the way we cultivate. We stop thinking of the tree as a possession and begin to see it as a temporary responsibility.

Perhaps that is one of the most discreet and, at the same time, most profound teachings of bonsai.
We do not own that which we care for with true love.
We only have the privilege of accompanying it for a brief instant of its long existence.

And when we finally accept this truth, bonsai ceases to be a tree grown in a pot and becomes something much more difficult to describe: a silent reminder that all life flourishes, matures, and continues beyond us, trusting that someone, someday, will continue to care for that which we received from those who preceded us.

A shared responsibility

Every credential acquires its true meaning through the work that continues after receiving it.

Every distinction is, in a way, a look toward the past. It recognizes the path traveled, the effort accumulated, and the dedication sustained over years. However, when that distinction is born of a living tradition, it also inevitably directs its gaze toward the future.

So it is with the International Instructors Program of Bonsai Clubs International.

Admission to this program does not represent the culmination of learning, because in a discipline such as bonsai, there is no definitive goal. There is always a tree capable of teaching us something we still do not know. There is always a stone that challenges our way of looking. There is always a master, a colleague, or a student whose experience broadens our own understanding.

In the Japanese tradition, a simple idea is frequently repeated: the path never ends. Not because the goal is unattainable, but because true learning consists precisely in continuing to walk.

Each season modifies the tree. Each rain imperceptibly transforms the stone. Each year also modifies the one who contemplates them. To learn means to accept this continuous transformation with humility.

In this sense, being part of the International Instructors Program means assuming a permanent commitment to study, research, and teaching. It is not enough to preserve what has been received. It is necessary to keep it alive, to deepen it, and to transmit it with fidelity so that it continues to grow without losing its essence.

Transmission constitutes one of the fundamental pillars of traditional Japanese arts.

One does not transmit only a technique.
One does not transmit only knowledge.
One transmits a way of observing.
A way of relating to time.
An attitude toward nature.
An ethics of care.
A sensitivity.

That is why teaching bonsai has never meant simply explaining how to prune a tree. It means helping another person discover a different way of contemplating the world.

When a student learns to pause before cutting a branch.
When they understand that a stone does not need to be modified to be beautiful.
When they accept that some answers will only arrive after many years.
Then authentic learning begins.

Everything else can be found in a manual.
But not this.

Throughout the centuries, countless Japanese masters dedicated their lives to preserving knowledge they never considered their own property. They received it from those who preceded them and delivered it, enriched by their own experience, to those who would come after. This continuity constitutes one of the greatest heritages of Japanese culture.

Each generation adds a small contribution.
None attempts to start from scratch.

This same idea inspires my work.

For more than two decades, I have endeavored to study, research, and share bonsai out of respect for its tradition, but also out of the conviction that knowledge only remains alive when it circulates freely among those who wish to learn with honesty.

Every lecture.
Every course.
Every article.
Every exhibition.
Every conversation held beside a tree or a stone.
It is all part of this same purpose.

Because, in reality, teaching never occurs only within a classroom.

It also happens during a walk on a mountain.
Before a carefully prepared tokonoma.
While observing a spring budding.
Or simply remaining in silence before a landscape.

With the passage of time, I have understood that one of the greatest privileges of this discipline consists precisely in contemplating how others develop their own path. Every instructor remembers the moment when a student stops repeating learned gestures and begins, finally, to see for themselves.

That instant is difficult to describe.
It cannot be measured by exams or certificates.
But it constitutes, perhaps, the greatest reward that those who dedicate their lives to teaching can receive.

Because transmitting knowledge has never consisted of creating disciples.
It consists of helping to form individuals capable of walking on their own.
People who, one day, will also transmit what they received.
And thus, a chain that began long before our existence will continue.

In Japanese aesthetics, there is a silent principle that runs through all traditional arts: nothing reaches its fulfillment when it remains isolated.

A tree needs the forest.
A stone needs the landscape.
A master needs their masters.
And also their students.
We are all part of the same continuity.

Understanding this deeply transforms the way we understand any recognition.

Credentials can be framed.
Diplomas can be preserved.
But none of them constitutes the true legacy of a life.
The legacy remains in people.
In what they learn.
In what they continue.
In what, perhaps without knowing it, they will transmit to others many years later.

If this journey has any meaning, I wish for it to be precisely that. To contribute, even if only modestly, to ensuring that bonsai continues to be a space of encounter between different cultures, generations, and sensibilities.

To continue learning with the same curiosity with which my first steps began. And to continue teaching with the same gratitude toward all those who made my own learning possible.

Because the bonsai will continue to grow when we are no longer here.
The stone will continue to keep the silence of the mountains for centuries.
Our life occupies only a brief instant between the two.

Perhaps the true responsibility consists in caring for that instant with respect, sharing it with generosity, and delivering it, a little richer, to those who will come after.

Epilogue

The tree will continue to grow when our hands can no longer touch it. The stone will remain where the water left it thousands of years ago. Between the two, a human life passes. Perhaps true learning consists in occupying that brief instant with serenity and transmitting it, intact in its essence, to those who will one day continue the path.

Colophon

Every tradition remains alive as long as someone is willing to learn it with humility, practice it with respect, and transmit it with generosity. That is, perhaps, the most valuable legacy that bonsai can offer to those who decide to travel its path.
