Facing Koji, Facing Koji
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.
The 29th head of the family, Yuichiro Murai
Product introduction
Amazake and koji seasonings to enrich your daily life. When you want to take care of yourself and take another step forward, they will gently accompany you in your own time.
Produced using carefully selected koji mold that brings out the best in color, aroma, and flavor. It is not pasteurized (heat sterilized) or diluted, so it is a rich, sweet, sweet sake that you would never guess is sugar-free. It is sugar-free, non-alcoholic, and made with domestic ingredients. It is a diluted type, so it can be used not only for drinking, but also as a sugar substitute or in a variety of other ways. Perfect as a reward for yourself or as a gift.
Make your own original koji at home. We sell seed koji, which is used by brewing companies and recognized by professionals, in sizes that are easy to make at home. It's up to you how you arrange the koji you make, as well as whether you want to make seasonings such as miso or soy sauce from koji. We also carry the industry's first "black koji mold" for home use.
For those who want to use koji casually, we also offer convenient frozen and dried koji. All koji is made using 100 % domestic ingredients. Fresh koji is frozen immediately after it is made to ensure that the original flavor of the koji is not lost. Dried koji is convenient and can be used on the day you want to use it, just by adding water. Please use it according to your purpose and preferences.
Simple chronology
This is a permission seal given by the 13th Shogun, Ashikaga Shogun, during the Muromachi period. When the company started its seed koji business, the wooden block was used to stamp the bags containing the seed koji and sell them as a license, which led to the company being called "Kuroban" (black seal), a nickname that is still loved by sake brewers all over the country today.
