Founded in 1986 in Oita Prefecture, Japan's leading shiitake-producing region, Marutomo Bussan specialises in dried shiitake mushrooms. Thanks to its location at the heart of this production's historic heartland, the company benefits from a regular supply of high-quality local products.
Home to the sector's largest warehouse and specialist factory, with a permanent stock of around 100 tonnes, it ensures rigorous quality and traceability management. A member of the Oita Dried Shiitake Traceability Council, Marutomo Bussan offers products verified by independent bodies and identifiable through a traceability seal system.
This commitment to quality and safety has earned it recognition from Japanese nutritionists and made it a preferred supplier to school catering services across Japan.
