Architecture shaped by climate, light, and human connection — from Hokkaido to the world.

At YKAA, we see architecture as the act of redefining boundaries—between inside and outside, nature and structure, tradition and the present.
In Hokkaido, where the seasons and light transform daily life, every design begins with careful listening: to the site, the materials at hand, and the people who will inhabit the space.

We believe architecture should hold both restraint and warmth. It is a place where daily gestures meet climate, where silence and light become part of living.

Each project is a search for continuity—between landscape and dwelling, between local knowledge and global dialogue.

Our work spans homes, studios, and small public spaces across Hokkaido and beyond, guided by an ethos of simplicity, precision, and sensitivity to place.
