Made from whole soybeans grown in Hokkaido and wheat from Ōmi, this Koshiki Shoyu is crafted with carefully selected domestic ingredients. Using sun-dried salt, the mash (moromi) is slowly fermented and matured for two full years in traditional wooden barrels before being pressed.

This soy sauce is completely unadjusted—no additional seasoning is added—making it an ideal choice for those who appreciate the sharp, distinctive character of authentic soy sauce. With its balance of depth and smoothness, Koshiki Shoyu offers a rich aroma and refined flavor, true to the time-honored tradition of natural, additive-free Japanese soy sauce.

How to use:

With its rich aroma, this soy sauce is perfect as a dipping or finishing sauce—its deep umami pairs beautifully with red-meat sashimi and stands up well to the richness of grilled meats. When used in cooking, just a small amount imparts both robust flavor and fragrance, making it an excellent choice for those who appreciate high-quality, artisanal soy sauce.
