Ishikawa Seed Koji Brewery, Ltd.

Established in 1956. We succeeded in collecting and cultivating black koji mold from the soil of a brewery on Yonaguni Island. As a specialist in supplying "seed koji", an important raw material for Awamori, Okinawa's local sake, we currently supply seed koji to 38 of the 46 Awamori makers in Okinawa Prefecture. At the same time, we have been researching and developing products using black koji, and have created new products such as "Black Koji Brown Rice Drink". Translated with DeepL.com (free version)
