Horaiya Honten was
established in 1906.

For over 100 years, we have been producing koji, the key to all of our products.
Koji is rice surrounded by koji mold and it is the first essential step in traditional Japanese fermented food culture.
Some foods derived from koji include sake, miso and amazake.

All of our products exhibit the beauty of our koji and have numerous health and beauty benefits from the koji.
Our mission is to continue implementing our traditional koji production process to provide
high quality products and to contribute to the health and fulfillment of society.
