Our History
The Mayuzumis are a multigenerational mushroom growing family based in Gunma prefecture, a mountainous region in Japan. In the 1970s, Fumimaru Mayuzumi discovered his proprietary reishi strain during one of his many forages in Gunma. With the perfect strain in hand, Mayuzumi developed natural wood-log cultivation to commercially grow reishi—a feat considered impossible to achieve for centuries.
Since their discovery, the Mayuzumis continue to dedicate themselves to sharing the healing benefits of red reishi.

Considered as one of the early pioneers of reishi cultivation, the Mayuzumis have been producers of high quality red reishi products for over 40 years. Today, their propriety reishi is used in all Mikei® products.
