Facing Koji, Engaging with Koji
Facing Koji, Engaging with Koji
Message from the Representative
Thank you for visiting the Kojiya Sanzaemon online store.
As a seed koji manufacturer founded during the Muromachi period, Kojiya Sanzaemon has been involved with koji for 600 years, refining its techniques. Through our long history with koji mold, we have come to feel the various possibilities that koji offers.
This site offers a wide range of items born from our pursuit of koji's potential, such as seed koji for experiencing koji making and amazake for enjoying the taste of koji.
Through these items, we hope you will experience the joy and richness that koji brings to daily life, and discover the potential of koji for yourself.
We will continue to be a public institution, constantly evolving both ancient and new practices, to contribute to the development of a food culture based on koji, of which Japan is proud.
Sanzaemon Murai, 29th Generation Head
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 gently accompany your personal time.
We carefully select koji mold that brings out the maximum color, aroma, and flavor. As it is unpasteurized (unheated) and undiluted, it has a rich sweetness that you wouldn't expect from a sugar-free product, just like freshly made amazake. It is sugar-free, non-alcoholic, and made with domestic ingredients. Since it's a concentrated type, it can be used not only as a drink but also as a sugar substitute and in various arrangements. Perfect for a treat for yourself or as a gift.
Make your own original koji at home. We sell seed koji, recognized by professionals and used by brewing manufacturers, in sizes adapted for home use. Whether you want to make seasonings like miso and soy sauce from koji, or arrange the koji you've made, the possibilities are endless. We also handle "black koji mold," a first for home use.
For those who want to easily use koji, we also offer convenient frozen and dried koji. All of our koji is made with 100% domestic ingredients. Fresh koji is frozen immediately after production to preserve its original flavor. Dried koji is convenient to use; just add water on the day you want to use it. Please choose according to your needs and preferences.
Brief Chronology
The license granted by the 13th Ashikaga Shogun during the Muromachi period. As a permit to start the seed koji business, it was stamped on the bags containing seed koji with a woodblock and sold, leading to the company being called "Kuroban" (black stamp), a nickname still beloved by sake breweries nationwide today.
