The world’s leading producer of traditionally-brewed soy sauce has started it’s Wisconsin expansion project. 

Kikkoman announced the expansion plan earlier this year and broke ground Wednesday at their new Jefferson site.  The new facility will produce soy sauce and soy sauce–related seasonings, including teriyaki sauce, with the first shipments of soy sauce planned for fall, 2026.

The new 250-thousand square foot facility will be Kikkoman’s second Wisconsin plant and third U.S. plant, and is about forty miles from their Walworth, Wisconsin production facility which began production in 1973.  Kikkoman officials say they are aiming for a sustainable next-generation production plant that combines flexibility with production efficiency and scalability for multi-production of a variety of products to meet customer needs.  The company’s other North American facility is in Folsom, California.
