Shimanto Hinoki

Tosaryu uses locally-harvested Hinoki cypress from the Shimanto area of Kochi prefecture. In southern Kochi, rapid photosynthesis leads to large and sturdy Hinoki cypress trees. The forests of Shimanto must withstand strong winds, making the trees particularly resilient and leading to increased oil production. In 70-80 years, the trees mature into a source of durable, fine-quality Hinoki wood.
