The path
One sensibility, running through four domains
- Music
A pianist, bound for Europe
Studied ethnomusicology and became a pianist. Explored improvisation with Lindha Kallerdahl in Sweden; made an album with Achim Tang in Cologne, where Stephan Desire taught him acoustics.
- Recording
Inheriting Kaneda DC recording
Back in Japan, studied under the leading authority Akihiko Goto — directly inheriting a purity of sound, half a century in the making, unreachable by commercial equipment.
- Software
Describing the world in software
Learned C and GPS positioning from Kazuhide Kobayashi of Geosense. Builds a browser-native music platform solo — frontend, audio engine, payments and all.
- Hardware
The feel of hardware
Restores Switzerland's legendary Revox decks himself — reading boards, soldering, verifying. That touch lives in the P-86S / X-86S microphones.

Philosophy / 久遠
In music, there is no single right answer.
Gathering the world's scattered musical craft into one. Even in the age of AI, art is something humans keep creating. Never cut, never harmed, changing shape yet never lost — the philosophy of emptiness his grandmother's towel taught, alive in everything he makes.
