Yaso is a project based in Chino City, Nagano, at the foot of the Yatsugatake Mountains. Working with local forestry businesses, it repurposes forest resources into products like tea, incense, essential oils, and interior goods.

Guided by the concept of 'living in harmony with the forest,' Yaso gives new value to trees removed through thinning and pruning, creating a sustainable cycle that supports and gives back to the forest.
