[Machine Translation] Japanese houses of unknown nationality are covered with new construction materials and trashed after 30 years or so. In the past, Japanese houses were made of wood from the nearby mountains, and carpenters built sturdy structures with a long life span by joining wood to wood. This was a beautiful townscape. How rational is the framework of an old minka house? What is the secret behind the open and earthquake-resistant house construction? What kind of house building is long-lasting house building that is rooted in the climate? Building houses learned from old private homes will connect the mountains, craftsmen, and residents, and lead to the revitalization of Japan's rugged mountains. This is a practical book that tells how to build the "Japanese house" of the future.
