“Reframing” Exhibition of DESIGNART 2024

“SOTOROJI #2” is part of the SOTOROJI series of spatial devices that lead from the ordinary to the extraordinary, utilizing the modern social affordance of “seeing a QR code and scanning it with a camera,” just as soto-roji (the outer garden,) in the chanoyu (the Japanese tea ceremony) serves as a space leading to a world of profound subtlety.
This work uses an old pine tree, considered a yorishiro (object capable of attracting spirits) for the god of performing arts, as its motif, expressing it through more than 130,000 QR codes across an area exceeding 100 square meters, becoming a boundary where physical and digital spaces, the ordinary and extraordinary, and reality and profound subtlety intersect. When viewers scan the QR codes, they are led to spaces of over 100 artists, testing whether they can transcend their own frameworks.

Alternative Computations, 2026
The universe computes. Life is computation. Mathematics is the language of this understanding. Change the language, the universe changes — the way of seeing changes. Sometimes, those in power choose which way of seeing prevails. What falls outside that choice is named error — and vanishes.
Japan once possessed a distinctive mathematics — wasan. Calculation practised as beauty, play, and offering to shrines: festive knowledge comparable to haiku and the tea ceremony. In the late nineteenth century, the Meiji government introduced Western mathematics in pursuit of national strength. Wasan was expelled. The cosmos its culture alone could see was closed.
At the destination Western mathematics has since reached stands quantum computing — yet its development is governed by utility and optimisation. Quantum noise is expelled as error. But quantum noise interferes, entangles, carries the past. There is another cosmos. This work recaptures it through the play and festivity of wasan.
The Alternative Computations series sculpts the cosmologies of lost vernacular mathematics. Built from quantum noise discarded by mainstream computing, this automated instrument takes sky, earth, and human as its three-layer structure. Twenty-eight sangi orbit overhead as the Twenty-Eight Lunar Mansions. A tatami floor defines the sacred threshold. More than four thousand reeds fill the space. The dancer’s movements, the tea master’s gestures, audience presence, and meteorological data are thrown into a quantum computer embedded in the ceiling’s sangi mechanism. High-dimensional dynamics set the sangi’s orbits and descend as rain sound. Mechanical creaking holds the weight of matter, anchoring experience between dream and waking. Thunder, wind, insects, cranes and frogs — a 28-minute sound collage. Each cycle ends a universe; another begins.
Quantum Art Festival 2026 Special Exhibition
“Alternative Computations: Worlds Otherwise Calculated”
Gunpowder can become either a weapon or fireworks.
This exhibition takes wasan—traditional Japanese mathematics, once a playful culture alongside haiku and the tea ceremony—as its point of departure, reclaiming calculation as a site of festivity rather than mere efficiency.
Showing my two new works, with performances by dancer @keika_misho and tea master @ryotaro_souryou_matsumura

昨年に引き続きMarché du FilmそしてCANNES NEXTとの共同企画の社交界「CANNES GALA」でパフォーマンス/ステージディレクションを担当しました。
今年は「いけばな」と「能」のクロスオーバーとして金春流シテ方 山中一馬 氏、大倉流囃子方大鼓 大倉正之助 氏と共演し源氏物語〈夕顔〉を披露。演目の〈夕顔〉をはこの日のために復曲、鏡板を本物の松として即興で花いけするなど特別編成で挑みました。
Following last year, I was in charge of performance and artistic direction at the high-society event “CANNES GALA”, a joint initiative with Marché du Film and CANNES NEXT.
This year featured a crossover performance of Ikebana and Noh. Together with Shonosuke Okura, Ōkura-ryū ōtsuzumi (drum) master, and Kazuma Yamanaka, Noh actor of the Komparu school, we presented Genji Monogatari – Yugao.
For this performance, Yugao was specially revived, and I arranged flowers improvisationally on the kagami-ita (back panel of the Noh stage) using a real pine tree, making it a unique production just for this evening.
Engaging in such overseas activities not only allows me to reaffirm my own position, but also to directly feel the profound depth that I believe is the true uniqueness of Japanese culture.
Always with Respect, and striving to Go Beyond, I will keep pushing forward on the world stage

Fuwafu-an is a phantom tearoom floating in the air. Guests are guided into the veiled tea house through the overpass ”Nijiri Guchi”, and the tea house itself floats in the air. Like a flying carpet, the teahouse itself floats in the air, inviting visitors to an extraordinary world of forests, rivers, and the universe.
