The Japanese are recognized as the foremost experts in reishi cultivation and were the first in the world to successfully grow the red mushroom variety — a feat considered impossible for centuries. In 1976, the Mayuzumi family, renowned mushroom growers in Japan, discovered and patented the most superior strain of red reishi, refining its cultivation and concentration to meet the exacting standards of the Japan Reishi Association (JRA).

The JRA is an international non-profit organization dedicated to upholding the highest standards of quality, safety, and integrity in the reishi industry. As a founding member, Nikkei Co. helped establish these standards and continues to play a leading role in their advancement.

Every Mikei® red reishi product is made with the proprietary Mayuzumi strain and crafted using the natural wood-log cultivation method perfected by the Mayuzumi family. The JRA mark on each Mikei® box is your guarantee of authenticity, safety, and superior quality.
