Katsuyama Construction is a team of craftspeople dedicated to mastering and preserving traditional Japanese construction methods.

Northern Nagano prefecture — also known as Kita-Shinshu — overflows with the culture and landscapes of traditional Japan.

Katsuyama Construction renovates kominka in and around the city of Iiyama, restoring these heritage homes and adapting them to modern lifestyles. Our workshop and headquarters are located in the neighboring city of Nakano.
