The Kominka Collective gives Japanese folk houses and traditional  wood, ceramic, stone, and paper materials a second life in other countries

Kominka: Japanese Folk Houses

The word kominka refers to houses built at least 50 years ago and in particular to those built before the Taisho Period. These structures are characterized by traditional Japanese timber framing using broad beams and posts, ceramic tiled roofs, and a rustic yet elegant beauty.


Japanese timber framing, used for wooden construction in temples, shrines, and folk houses, has many advantages, including strength, durability, and maintainability - as well as its elegant appearance.


Komika were constructed with high-quality local wood, including zelkova, sakura, chestnut, and cypress. The naturally dried old beams and posts in these old houses are stronger and last longer than the wood used in modern structures as wood gains in strength for 200–300 years after being cut. The all-wood joints used in traditional Japanese building also become stronger as the wood ages. 

The Kominka Collective

Toda Komuten disassembles old Japanese folk houses which are in very good condition but are scheduled to be demolished and rebuilds them for use as homes, studios, home offices, and shops. They are passionate about maintaining the integrity of the Japanese aesthetic while using modern technology to ensure that reconstructed komika are comfortable and energy-efficient spaces in which to live and work. We also incorporate materials from these old houses in new or existing structures and landscapes, as well as using them to create one-of-a-kind furnishings.

Toda Komuten, a longtime advocate for folk house preservation in Japan, and Zen House formed the Kominka Collective to bring traditional Japanese folk houses and reclaimed materials to the United States to provide people outside Japan opportunities to live with and enjoy traditional Japanese architecture and to give these beautiful houses and irreplaceable materials a second life.
