Yamasa Soy Sauce

Yamasa Corporation is one of the oldest and most respected soy sauce producers in the world, with a history dating back to 1645 in Choshi, Chiba Prefecture, Japan. The brand is renowned for its specific brewing techniques that produce a deep color, rich aroma, and a refined taste that has traditionally been preferred by the Japanese Imperial Household and high-end restaurants.

While the main production facilities remain in Japan, Yamasa has expanded its global presence significantly to meet international demand. The company established Yamasa Corporation USA in the 1990s, with a brewing plant in Salem, Oregon, to serve the North American market. Despite this international production, the brand maintains its identity as a quintessential Japanese craft product, with most premium variations still exported directly from Japan.

As of 2026, Yamasa Corporation remains an independent, family-controlled entity, a rarity among major global food producers. It continues to focus on traditional fermentation methods while diversifying into biotechnology and pharmaceutical ingredients, leveraging its expertise in microbial research developed through centuries of soy sauce brewing.
