Koji is the secret ingredient for culinary bliss.

Koji, a miraculous microorganism, works wonders by enhancing the flavor, nutritional value, and preservation of food, while also contributing to our health and beauty. It holds a revered status as Japan's national bacterium.

Essential ingredients like miso (soybean paste), soy sauce, sake, mirin (sweet sake), and vinegar, all produced through koji bacteria fermentation, are indispensable in Japanese cuisine, which has earned UNESCO recognition as an intangible cultural heritage, drawing global admiration.

Despite its significance, many remain unaware of the wonders of koji culture and its versatile applications.
That's why we founded the "Japan Koji Culture Association," dedicated to sharing the allure of koji culture, integrating it into our daily lives, and proposing a more abundant existence enriched with koji.

Koji culture, a precious gift from our ancestors, requires patience and reverence in our modern, fast-paced lives. Yet, its preparation is simple – by combining koji and ingredients, industrious microorganisms work their magic, slowly fermenting and transforming food into delectable delights.

We envision countless individuals embracing this ancestral wisdom, relishing the richness of life with koji, and perpetuating malt culture not only within Japan but also worldwide.
