Architecture that listens

Selected Works

Projects

A selection of residential and cultural commissions from the past decade. Each begins with a site visit and ends with a building that belongs to its place.

House of Six Shadows
Residential Completed 2023

House of Six Shadows

A single-family residence in Kamakura organized around six courtyards, each calibrated to catch light at a different hour. Cedar screens modulate the boundary between interior and garden, dissolving the line between architecture and landscape.

Kamakura, Kanagawa 280 m²
Aoyama Atelier
Cultural

Aoyama Ceramic Atelier

A workshop and gallery for a fourth-generation potter. The building borrows rooflines from neighboring machiya, reinterpreting them in board-formed concrete and reclaimed keyaki wood.

Minami-Aoyama, Tokyo 160 m²
Teshima Reading Room
Cultural Completed 2022

Teshima Reading Room

A small public library on the Seto Inland Sea. A single pitched roof rests on laminated beams, framing uninterrupted views of the water. The reading desk runs the full 22-meter length of the room.

Teshima, Kagawa 95 m²
Moss Garden Pavilion
Pavilion

Moss Garden Pavilion

An open-air tea house in the Adachi Museum gardens. Four columns, one roof, nothing else.

Yasugi, Shimane 28 m²
Roppongi Apartment
Residential

Roppongi Apartment

A 120-square-meter interior renovation that removes every non-structural wall, replacing them with sliding shoji panels on a single grid.

Roppongi, Tokyo 120 m²
Naoshima Guest House
Hospitality Completed 2021

Naoshima Guest House

A four-room inn on the art island of Naoshima, built from local stone and oxidized steel that will weather over decades.

Naoshima, Kagawa 210 m²
Philosophy

"A building should disappear into the life around it. The best architecture is the kind you stop noticing — and never stop feeling."

— Kenji Tanaka, in conversation with Domus, 2023
01

Begin with the site, not the brief

Every project starts with multiple visits across different seasons. The architecture follows what the land, the light, and the existing context already suggest — never the other way around.

02

Proportion over decoration

The work relies on the relationship between masses and voids, not applied ornament. A well-proportioned room needs nothing else. This is the oldest idea in Japanese architecture, and it remains sufficient.

03

Materials that age honestly

Cedar, plaster, stone, and oxidized steel are chosen for how they change over time. A Tanaka building looks better in its tenth year than in its first — the surface records the years.

04

Drawn by hand, built by hand

Schematic designs are drafted in pencil on washi paper. Construction details are developed alongside the carpenters and plasterers who will execute them, on site, in real time.
