100 Years of Kokufu - Is Bonsai the Most Underrated Alternative Asset?
Bonsai Is Not Horticulture
Let's make one point clear at the outset. Bonsai is not horticulture. It is not houseplant decor. It is not garden stock.
:::img{ key="bonsai_not_horticulture" }:::
As "green interior" trends have expanded, small bonsai increasingly appear on the same shelves as ordinary houseplants at IKEA and Amazon. Karen Harkaway, president of the American Bonsai Society, has noted that some people see bonsai as a houseplant category, while others see it as fine art. That split exists globally. This article addresses the latter. Where decorative plants are selected for ease of care, top-tier bonsai are singular works that can command prices from several hundred thousand to tens of millions of yen and be handed down across generations.
So why call bonsai "art" - and a fundamentally different kind of art?
Most art starts with inert material: canvas, marble, bronze. Once the artist has finished, the work freezes and thereafter only declines. Bonsai reverses every one of those rules. The material is alive. The work is never finished. Multiple caretakers across generations become co-authors. And unlike any other art form, bonsai can die. Continued life is itself part of value.
Kunio Kobayashi, founder of Shunkaen Bonsai Museum, recalls the moment that pulled him into bonsai. At an exhibition he stood before a 600-year-old Japanese white pine called "Oku no Kyosho." Its trunk had hollowed and turned bone-white over centuries, surviving through nothing more than a thin strip of living bark. He describes the encounter as a shock that "struck him to the core." Forty-four years later, he still insists that "bonsai as a living art is eternally unfinished and never stops evolving."
A Rembrandt painted in 1642 will look essentially the same in 2642, behind UV glass. A bonsai collected from a Japanese mountain in 642 and cultivated for 1,400 years may be more complex, more beautiful, and more valuable in 2642 - precisely because it is alive. Time itself functions as the medium: the world's only art form where this is true. That is where understanding bonsai must begin.

The Azukari Ethos - A Culture of Entrusted Continuity Unique to Bonsai
There is another quality that separates bonsai from every other collecting category: the concept of "azukari" - entrusted stewardship.
:::img{ key="history_scene" }:::
Japanese bonsai professionals do not think of great trees they care for as things they "own." They think of themselves as "receiving on trust" from the previous generation. The time they get to spend with a tree is only a small fraction of that tree's life. Their job is to improve the tree through their own skill and pass it on to the next generation in a better state than they received it.
This philosophy is not unique to bonsai - it runs through Japanese culture more broadly. The "provenance" of tea utensils, the "transmission" of swords, the "inheritance" of Noh masks. But bonsai carries a special urgency that no other cultural object shares, because what is being entrusted is alive. A single season of poor care can erase decades of accumulated work. The responsibility of azukari exists literally within every daily watering.
Kobayashi draws a parallel between raising disciples and raising trees, centering both on three words: individuality, harmony, and dignity. Every tree has a unique character. The task is to draw that character out, correct its weaknesses without erasing them, and gradually refine the whole toward something dignified. This process rarely completes within a single artist's lifetime. It passes from master to apprentice, from one generation to the next. The transmission of technique itself is part of the azukari chain.
Trees whose chain of stewardship remains unbroken become meiboku - famous trees. Exhibitions are where those lineages are made visible.
:::cta{ variant="waitlist" }:::
Owner and Artist - Bonsai's Unique Co-Creation Structure
There is one more structure essential to understanding bonsai: the relationship between "owner" and "artist."
:::img{ key="owner_artist_goyomatsu" }:::
At top-level bonsai exhibitions, entries are shown under the owner's name. The artist who performs the daily, highly skilled work may remain far less visible publicly. Owners receive honor, historical recognition, and the growth of value. Artists build reputation and trust through technique, earning their next commissions and the ability to take on disciples. And through this collaboration, the tree continues to grow in value across centuries.
This resembles the gallery-artist relationship in fine art, or the chateau owner-winemaker relationship in fine wine - but with one crucial difference: the work is alive. A painting does not evolve after the artist has finished. A bonsai does. When a new artist takes over stewardship, the tree continues to grow, to be refined, to evolve. Co-creation continues across generations. A great bonsai has not a single author but a dynasty.
For young bonsai artists, exhibitions are the stage where they prove their skill within this structure. They bring a tree entrusted by an owner to its finest state, enter it in the exhibition, and receive evaluation. Recognition there earns the next owner's call and the chance to be entrusted with still-finer trees. Just as Kobayashi entered the bonsai world at 28 - a late start by industry standards - yet "swept exhibition prizes with unstoppable momentum," exhibition results determine an artist's career.
And Japan's oldest, most prestigious, most rigorous exhibition just reached its 100th edition. February 2026, Tokyo Metropolitan Art Museum in Ueno. I attended the second half.

What Is the Kokufu Bonsai Exhibition?
Before getting into the main report, a brief introduction to the exhibition itself. In a single phrase: the Olympics of bonsai.
The first edition was held in March 1934 at the Tokyo Prefectural Art Museum (today's Tokyo Metropolitan Art Museum). The founding body was Kokufu Bonsai-kai, whose inaugural chairman was Count Yorinaga Matsudaira, later President of the House of Peers. The name "Kokufu" - meaning the customs and culture unique to a nation - encoded a deliberate intention to frame bonsai as a Japanese art form.
:::image-left{ src="/asset/100th-kokufu-bonsai-exhibition-thumb.jpg" alt="Ticket visual for the 100th Kokufu Bonsai Exhibition" }:::
On the advice of sculptor Fumio Asakura, who suggested "bonsai is for enjoying the seasons - spring and autumn are ideal," the exhibition was held twice a year before the war. A three-year interruption during World War II followed. When it resumed in 1947 at the same Ueno museum, it played a role in healing hearts shattered by the long war and conveying the relief and joy of peace returned.
In 1965, the Nippon Bonsai Association was established on the foundation of Kokufu Bonsai-kai, with former Prime Minister Shigeru Yoshida as its first chairman, and the Association inherited operation of the Kokufu exhibition. It has preserved the tradition ever since as Japan's oldest and highest-level bonsai exhibition. In February 2026, that exhibition reached its 100th edition.
Why "100" Is Special
The Kokufu Bonsai Exhibition is not simply a count of repetitions. The 92 years it represents are the history of bonsai's transformation - from a pastime enjoyed by a narrow circle of enthusiasts at tea ceremony gatherings and restaurant display events in the late Meiji era, into "art open to the general public in a museum."
The process through which bonsai editor Norio Kobayashi developed what might be called a "bonsai art movement" and, with the support of Fumio Asakura, achieved museum-level exhibition - this was the turning point at which bonsai changed its public identity from "hobby" to "art." For the 100th edition specifically, a commemorative ceremony was held, alongside bonsai demonstrations, special displays of historic trees, screening of commemorative films, and performances of traditional Japanese performing arts - a program well beyond the usual format.
First Half and Second Half - Kokufu's Distinctive Two-Period Structure
:::youtube{ id="bz73DJNXiws" title="100th Kokufu Bonsai Exhibition" }:::
The Kokufu Bonsai Exhibition is divided into a first half and a second half. For the 100th edition, the first half ran February 8-11 and the second half February 14-18. The days in between - the 12th and 13th - were for complete replacement of works. Entirely different trees were shown in each period, meaning anyone wishing to see the full lineup needed to attend both.
In the bonsai world, there is a long-standing belief that "the famous trees appear in the second half." Second-half displays tend to include past Kokufu Prize winners and trees whose owners choose the 100th milestone as the occasion for a special showing. Among enthusiasts, the second half draws greater attention. This report is from the second half. True to the milestone occasion, the venue held a particularly dense gathering of historic masterworks. Admission was ¥1,000 for general visitors, ¥1,500 for a combined first-and-second-half ticket, and free for high school students and below. No advance tickets were available; tickets were purchased at the venue on the day. Members of the Nippon Bonsai Association entered free.
What We Saw On Site - More Than 60% of Visitors from Overseas
:::img{ key="crowd_scene" }:::
The first surprise on entering the Tokyo Metropolitan Art Museum was the composition of the crowd. Looking around the venue, the sounds that reached us were English, French, Spanish, Chinese. By feel, somewhere between 60 and 70 percent of visitors had come from outside Japan. European and Asian visitors were particularly prominent.
This matches the reality at Shunkaen Bonsai Museum, where roughly 80% of visitors are foreign nationals. Bonsai is no longer "an old man's hobby in Japan." The global bonsai market has been reported to exceed one trillion yen, and for overseas collectors and enthusiasts, the Kokufu exhibition has become something like an annual pilgrimage to Mecca.
Japanese visitors left a strong impression as well. Older enthusiasts could be seen stopping in front of trees with grandchildren in hand. Young people with smartphones were far from rare. The 100th Kokufu venue made it unmistakably clear that bonsai draws interest across generations.
The "Bonsai Japan Tour" Phenomenon - Another Reason to Come to Kokufu
Many of the overseas bonsai fans who gather at Ueno during Kokufu are not traveling only for the exhibition. Most of them organize what they call a "Bonsai Japan Tour," using Kokufu as their starting point and building itineraries that take them to bonsai nurseries and artists across Japan.
Omiya Bonsai Village, Kyoto bonsai nurseries, famous gardens in Shikoku, growing regions in Kyushu. Solo or in small groups, they make pilgrimages to the sacred sites of Japanese bonsai. They speak directly with artists, look at trees up close on the benches, and absorb an atmosphere that cannot be found anywhere else. For them, bonsai is not an image on a screen - it is something to be experienced in person, with all five senses, in the place where it exists.
And yet there is a hard reality here. They cannot take Japan's great trees home with them. Phytosanitary regulations require that bonsai destined for export be managed for a minimum of three years in a designated export-ready nursery. Physically taking home a tree they fell in love with at Kokufu is impossible.
Moreover, most meiboku are not for sale in the first place. Here the azukari ethos described earlier reasserts itself. For Japanese bonsai professionals, a historically important tree is something received on trust from predecessors - not something to be released on one's own watch. The shimpaku "Hokusai," reworked by Saburo Kato, continues to be carefully managed by Shinji Suzuki. It is not merchandise; it is a cultural property to be passed across generations.
Traveling to Ueno once a year from overseas, touring Japan, holding their breath before great trees - yet their relationship with those trees must stop at "looking." This structural condition tells two stories simultaneously: the rarity of bonsai as a cultural asset, and the necessity of a new model of ownership.

The Presence of the Master Trees - Special Displays Worthy of the 100th Edition
Across both periods combined, more than 150 historic masterworks were assembled at the 100th Kokufu. Three left the strongest impression.
Shimpaku "Hokusai" - 3,000-Year-Old Mountain Witness
:::image-left{ src="/asset/shimpaku-hokusai.jpg" alt="Shimpaku 'Hokusai'" }:::
Exhibited as a special commemorative display for the 100th edition, this shimpaku - property of Shinji Suzuki of Nagano Prefecture - is a wild-collected specimen from Mt. Myojo in Niigata, with an estimated age of approximately 3,000 years. Around forty years ago, Saburo Kato - founder of Omiya Bonsai Village, president of the Nippon Bonsai Association, chairman of the World Bonsai Friendship Federation, and executive director of the First World Bonsai Convention - reset its front and performed a major rework that produced its current powerful form.
When people hear 3,000 years, most wonder if it can be true. Wild-collected shimpaku grow on the cliff faces of the Japanese Alps and Niigata's mountains in extreme conditions, developing with extraordinary slowness. Their annual rings are no wider than a sheet of paper. Over millennia, the interior of the trunk turns bone-white while a sliver of living bark continues to sustain life. The same image of "the dignity of life" that Kobayashi saw in Oku no Kyosho is here. The form transcends what we call bonsai - it is more accurately a natural sculpture that embodies geological time.
Here the azukari chain described earlier becomes visible. From the mountain collector to Saburo Kato, from Kato to Shinji Suzuki: a 3,000-year life has passed hand to hand like a relay baton, arriving at the stage of the 100th Kokufu. The question now is: who will carry it through the next hundred years, and how?
Imperial Red Pine - An Entry from the Imperial Household
:::image-left{ src="/asset/imperial-akamatsu.jpg" alt="Imperial red pine (Imperial Household Agency entry)" }:::
The Kokufu exhibition regularly includes a special entry from the Imperial Household Agency - "bonsai from the Imperial Palace." Where the black pine is called "male pine," the red pine is called "female pine" for its finer, softer needles and the reddish tinge of its trunk and new growth.
The Imperial family's relationship with bonsai runs deep. Bonsai spread to political and financial circles following Emperor Meiji's well-known appreciation for it, establishing the image of bonsai as "a gentleman's pastime." At the 98th Kokufu, Their Majesties the Emperor and Empress and Princess Aiko attended and were recorded by the Imperial Household Agency viewing works with evident concentration.
At the 100th Kokufu as well, it was reported that Their Majesties and Princess Aiko visited the venue and viewed bonsai cultivated by enthusiasts from Japan and abroad. The milestone of 100 editions made the cultural standing of bonsai as a Japanese tradition newly visible.

The Imperial Palace manages many bonsai including Japanese white pine, black pine, red pine, needle juniper, and Japanese maple, displayed in the southern reception room, the north porte-cochère, and the Matsukaze room of the Imperial Palace. Opportunities for these trees to appear publicly are extremely rare. There have been editions where a black pine shown for the first time in 37 years became the talk of the exhibition. What atmosphere surrounded the Imperial red pine at the 100th edition is something only those who were there can know.
Tosho Juniper - "Ascending Dragon" from Aichi
:::image-left{ src="/asset/tosho-juniper.jpg" alt="Tosho juniper with an ascending-dragon form" }:::
The tosho (needle juniper) entered by Zenkyo Okushu of Aichi Prefecture has received prizes at both the Kokufu exhibition and the Taikan exhibition. Needle juniper stands alongside shimpaku as a representative of the pine-and-cypress class; its hard trunk and sharp needles reaching toward the sky in a form that evokes an ascending dragon. Recognition at two of the highest-level stages means this tree's quality is not a one-time novelty but a standard that holds up under different eyes and different judging criteria.
An overseas attendee's words on seeing the scene were striking:
"About 150 historic trees were on display, including a 3,000-year-old pine, a tree gifted by the Emperor, and the magnificent 'Ascending Dragon' juniper - truly the finest gathering of bonsai I have ever witnessed. I was deeply moved."
These words are not an exaggeration. Every tree in the Kokufu venue carries decades, centuries, sometimes millennia of accumulated time. That density is something no other bonsai exhibition in the world can offer.
:::cta{ variant="owner" }:::
The Overlooked Companion: The Suiseki Exhibition
What is less widely known is that a suiseki exhibition runs at the same time as the Kokufu Bonsai Exhibition. Suiseki are naturally formed stones in which the viewer discerns mountain landscapes or animal forms; placed on a carved wooden stand or in a water tray, they are appreciated as a distinctly Japanese art form.
:::img{ key="suiseki_scene" }:::
Bonsai and suiseki have long been displayed together as a pair. Arranging bonsai, a hanging scroll, and suiseki (or an accent piece) in the tokonoma alcove to express the mood of a season - this "seat display" (sekikazari) is considered the essence of bonsai appreciation. It is precisely this world of sekikazari that Kobayashi, as the third-generation headmaster of Keido - the Way of Bonsai Display - is working to transmit. Tree, scroll, and accent are arranged to evoke a seasonal landscape. The viewer's task is to perceive the host's unspoken intention. That silent conversation carries a depth akin to Zen dialogue.
The suiseki exhibition draws smaller crowds than the bonsai exhibition, but it is indispensable for understanding bonsai in full context. Rather than seeing bonsai alone and leaving, knowing the relationship with suiseki reveals the depth of bonsai as a total art form - the sekikazari as integrated aesthetic system. If you have the opportunity to attend Kokufu, going a step further to the suiseki exhibition is strongly recommended. Information on the suiseki exhibition can also be found on the official site (suisekiten2026.jp).
Market Size Dispersion - A Signal of Immature Price Discovery
The global bonsai market size swings widely depending on definition. Some reports put the broad market (from interior-oriented mass products to artistic bonsai) at around USD 8.4B in 2024, while Bloomberg's 2025 "over one trillion yen" framing is often used in a high-end context. Either way, there is little disagreement that global demand is accelerating.
:::img{ key="market_size_chart" }:::
Individual transaction prices also show the depth of this market. At the 2012 Takamatsu World Bonsai Convention, a Japanese white pine over 800 years old was reportedly traded for about USD 1.3M, and records indicate comparable levels for top-tier shimpaku in similar contexts. However, these were not open-auction sales but deals formed inside private networks among artists and collectors.
Unlike wine or contemporary art, bonsai still lacks a mature secondary market with transparent price discovery. Value clearly exists in masterpiece trees, but there is no robust infrastructure to evaluate that value objectively and provide liquidity. Seen from another angle, this opacity itself is where major upside can emerge once proper market infrastructure is built.
:::cta{ variant="waitlist" }:::
The Structural Challenge Behind the Celebration
While the 100th edition is a milestone to celebrate, the history of this exhibition also makes visible the structural challenges facing the bonsai world.
Most of the masterworks on display at this year's Kokufu were cultivated with great care by enthusiasts 50 or 100 years ago and passed down to this generation. But the people doing that "passing" are rapidly disappearing. The aging of bonsai craftspeople and the shortage of successors is severe, and cases are increasing where great trees flow out of Japan without proper care, or are picked up cheaply by dealers who do not understand their value.
As fewer practitioners with the skill and discernment of Saburo Kato - who reworked the shimpaku "Hokusai" - remain, what is needed is a system for carrying a 3,000-year life through the next hundred years. Kobayashi has acknowledged that "given declining birth rates, population contraction, and every other trend," Japan's bonsai world cannot sustain itself in its current form, and has called for commitment to the next generation and deeper international exchange.
As noted earlier, overseas enthusiasts cannot take great trees home with them on the spot. Meanwhile, the shortage of successors within Japan is leading to the dispersal of masterworks. Resolving this contradiction requires a new system - one that keeps great trees in Japan under proper care, while allowing people around the world to build real relationships with them.
What Japanese bonsai professionals call azukari - the act of receiving a great tree from predecessors on trust and passing it to the next generation - extended as a system: combining digital ownership with on-site professional care in Japan. That is one answer for protecting bonsai as a cultural asset while opening it to the world.
This is not a sentimental argument - it is the thoroughly practical problem of cultural asset preservation. With the global bonsai market reported to exceed one trillion yen and overseas demand rising, efforts to redefine the azukari spirit through modern technology are beginning.
Conclusion
Bonsai is not horticulture. It is the world's only art form that uses time itself as a living medium - sustained through the azukari chain, an unbroken intergenerational co-creation without parallel anywhere else. The highest-level stage for that art, the Kokufu Bonsai Exhibition, has reached its 100th edition after 92 years of history.
The 3,000-year shimpaku "Hokusai," the Imperial red pine, the tosho that earned recognition at both Kokufu and Taikan: the masterworks assembled at the venue proved once again that bonsai is a "living cultural asset."
The reality that more than 60% of visitors came from overseas, and that "bonsai Japan tours" have become a fixture, is proof that bonsai's value has been recognized globally - and simultaneously a question of whether Japan can continue to protect that value at its source. While export regulations and the azukari culture are still holding great trees in Japan, the task is to build the systems that will sustain the next hundred years: maintaining the owner-artist co-creation structure while expanding its stage to the world. That is the most urgent challenge that 100 editions of Kokufu history now demands.
