KOUJI uses HIDEKAWA’s naturally handmade tofu made of 100% non-GMO soybeans from Taiwan. A quality strain, kouji, from a Japanese miso store over 300 years old is integrated with koji cultivated in the organic rice from Loushan, Hualien, and the combined ingredients are ripened to make naturally fermented foods, such as miso, Shio Koji, mirin, amazake, sake and distillers’ grains. These nutritious and delicious fermented substances are then used flexibly in each cuisine, creating simple and pure “natural cuisines”.
