Greetings from the Representative
Thank you for visiting the Kojiya Sanzaemon Online Store.
We at Kojiya Sanzaemon have been involved with koji and honed our techniques for 600 years as a koji starter manufacturer founded in the Muromachi period. Through our long history of working with koji mold, we have come to realize the various possibilities of koji.
This website offers many items that were created in our pursuit of the possibilities of koji, including koji starter, which allows you to experience making koji, and amazake, which allows you to enjoy the taste of koji.
It is our hope that through these items, our customers will be able to experience the joy and richness that having koji in their daily lives brings, and that they will be able to discover the potential of koji for themselves.
As a public institution, we will continue to evolve in a way that combines old and new to contribute to the development of Japan's proud food culture, which is based on koji.
