Company Outline

For generations, we have preserved and used large wooden barrels for fermentation. These barrels are crafted without a single nail, a skill that only a few artisans in Japan can still master today. The brewery’s wooden beams and barrels are home to natural microorganisms essential for fermentation, which play a crucial role in determining the depth of flavor and aroma of our soy sauce.

We are committed to using 100% domestically sourced ingredients, with whole soybeans from Japan and wheat from Gunma Prefecture. Our Organic Dark Soy Sauce (First Press) and Organic Double Aged Soy Sauce are made from rare, domestically grown organic whole soybeans and organic wheat, ingredients that are extremely limited in Japan.

Ensuring trust and safety requires more than just premium ingredients and traditional methods. In 2020, inspired by the Tokyo Olympics, we conducted the largest modernization project since the Meiji era, achieving global standards by obtaining ISO and FSSC22000 certifications. Today, with state-of-the-art facilities and stringent quality control, we continue to produce safe, high-quality products for customers worldwide.
