A few weeks ago we celebrated the exciting news of “Traditional Sake Brewing with Koji” being listed as a UNESCO Intangible Cultural Heritage (if you missed it you can find out more here) and in this episode, we decided to dive deeper into the world of koji as we had the immense pleasure of interviewing Higuchi Koichi, owner of Higuchi Matsunosuke Shoten Co., Ltd. and one of the experts in koji starter manufacturing in Japan!

So join us as our regular hosts Rebekah Wilson-Lye, John Gauntner, and Arline Lyons sit down at our base, the Japan Sake and Shochu Information Center with Higuchi Koichi to dive into the fascinating world of koji—the mold at the heart of Japanese fermentation culture. 

Learn more about what koji is, as Higuchi breaks down the different types of koji (yellow, white, black) and their unique roles in sake brewing, miso, shoyu, and other fermented foods. He also shares his journey into the koji industry and a behind-the-scenes look at the production process, the types of koji his company produces, and some of his ongoing projects in the world of fermentation. Although many of them are rather secret, he was able to share some details about a recent collaboration with Kewpie (possibly the best-selling Japanese brand of mayonnaise in Japan) and how he is creating “egg koji” for them on a quest to bring more umami to their products…

For anyone curious about Koichi Higuchi and his company Higuchi Matsunosuke Shoten Co., Ltd., you can find more information here and if you would love to learn more about Koji and how it is used in Sake brewing check out our “Episode-23: Koji Basics” to get started.

As always, if you have questions or comments please do share them with us at [email protected] or head over to our Instagram, Twitter, and Facebook we would love to hear from you!

We’ll be back very soon with plenty more Sake On Air.

Until then, kampai!
