As a "Yamacho brand" material from Kishu, the spotlight in the industry is on cedar square timber. Traditionally, the mainstream for beam materials has been American red pine square timber, but Kishu cedar has been proven to possess greater strength than red pine and is suitable for beam materials in terms of long-term resistance to deflection and long-term allowable application strength.

Growing trees is about protecting the natural environment. At Yamacho's forest, it starts with the cultivation of a single seedling and goes through a series of time-consuming and labor-intensive tasks such as afforestation, thinning, and underbrush clearing, ultimately leading to logging and transportation operations. We are helping to protect the mountains and contribute, albeit modestly, to the conservation of the natural environment.
