At Marunaka Shoyu, tradition is embraced each and every day.
Time-tested equipment and brewing methods, passed down for generations, are the cornerstone of a process proven to yield an exceptional product.
Many of the tools and equipment once used by breweries to produce shoyu, or soy sauce, can be found on display in historical museums across Japan. At Marunaka Shoyu, however, these same tools and equipment are masterfully employed, backed by the belief that perfection comes through continuous involvement, not automation.
While there are a number of well-established soy sauce manufacturers in Japan, Marunaka Shoyu is one of the few remaining breweries still dependent on traditional practices and instruments. For this reason, the breweries of Marunaka Shoyu have been recognized by the Japanese government as a National Tangible Cultural Property.
