Through four centuries, YAMASA Corporation has continuously manufactured the finest quality soy sauce available to meet the tastes of our customers both then and now. As we approach our fourth century, we pledge to maintain this tradition of product excellence and value.
YAMASA Corporation began exports of soy sauce to the U.S. in 1886. Demand for the product has steadily grown, and in June 1992, YAMASA incorporated the USA subsidiary in Salem, Oregon, marking a memorable page in YAMASA’s history and establishing a U.S. production and distribution facility.
We have three sales offices in L.A., N.Y. and Atlanta and we synergize with San-J International, Inc.

In 1645, YAMASA has started brewing soy sauce in Choshi, Chiba. Since then, the YAMASA factory in Choshi has established the first and second factories in the surrounding 23 hectare area, where soy sauce and soy sauce related seasonings are produced and shipped out.
The 83,000 square foot plant situated on a 20 acre site.
Why Salem, Oregon?
Oregon’s moderate climate, humidity, and water quality are instrumental in the brewing of soy sauce by environmentally assisting the required fermentation process that produces a mellow, distinct taste. The product is made during a six-month fermentation process that utilizes the finest soybeans, wheat, and salt.
