We are nearing the end of our shipping season.

Shipping to western and southern states (Regions B, C, & D) has now closed.

We will resume shipping nationwide in the fall of 2025.

Thank you for a wonderful season!

We make Brown Rice Koji (the Japanese term for cultured grain) by inoculating steamed rice with the spores of the Aspergillus mold. During a two-day fermentation process the rice is transformed into sweet, fragrant koji, which we use to make our varieties of rice miso.

Our dried rice koji is available for customers, who use it primarily for making amazakรฉ, a delicious sweet rice pudding. Amazakรฉ can also be used as a homemade sweetener substitute for sugar in many recipes, a sweetener derived entirely from rice.

Rice koji is also used as a starter for making a number of other fermented foods besides miso and amazakรฉ, such as sakรฉ, rice vinegar, and mirin.

Sold in one pound packaging; one pound = 2 2/3 cups.
