Shoyu Koji, a fermented mixture of soy sauce and koji rice spore, has a mild but rich umami flavor. Shoyu Koji is milder in taste and richer in umami when compared to regular soy sauce. It is a natural umami enhancer and tenderizer. It can be used as a seasoning, dressing, sauce, marinade, or dip, and can also be used to make soup, bread, cookies, and more.

Shoyu Koji is currently available in select stores only. Contact your local market to find out if they carry Marukome koji products.
