What is a kominka?
Kominka (古民家) literally means "old house." In practice, it refers to traditional Japanese farmhouses built before World War II, typically using timber frames, thatched or tiled roofs, and earthen walls. These houses were designed for a farming family's needs: a large central room for living and working, a kitchen with a sunken hearth (irori), and storage spaces for tools and harvests.
What makes kominka special is the craftsmanship. The wooden joints are cut to interlock without nails. The beams are shaped by hand to account for the natural curve of the tree. A well-built kominka can last 150 years or more if maintained.
We restore them carefully. Toshi replaces rotted beams with new timber from the same species, cut from the same region. We upgrade insulation, plumbing, and electrical systems, but we keep the structure, the proportions, and the materials intact. The goal is not to modernize — it's to make the old house livable again.
