The architecture of a single day.

一日の設計。

Founded on the strict principles of Japanese minimalism and structural discipline, ichinichi studio is an ongoing study of the daily rotation. We do not chase seasonal shifts or temporary noise. Instead, we engineer permanent, uncompromising artifacts—garments and objects of utility designed with absolute visual weight, stark typography, and brutalist form. This is not a clothing brand; it is a master archive dedicated to the pure, physical manifestation of a single day.
