Yamasa Brewed Soy Sauce

Yamasa is one of Japan's most historic and prestigious soy sauce brands, with a heritage dating back to 1645. Originally founded in Choshi, Chiba Prefecture, by Gihei Hamaguchi, the brand became famous for supplying soy sauce to the Tokugawa Shogunate during the Edo period. The Choshi region was chosen for its ideal climate, characterized by high humidity and cool summers, which are perfect for brewing high-quality soy sauce.

Today, Yamasa remains a powerhouse in the condiment industry, still owned and operated by the Yamasa Corporation. While they have expanded globally with production facilities in other regions like North America to meet international demand, the specific product shown—labeled as brewed in Choshi, Chiba—is manufactured in their original Japanese home. The brand is celebrated for its deep reddish color and complex flavor profile, achieved through traditional brewing methods combined with modern quality standards.
