Kikkoman Opens Third U.S. Soy Sauce Plant in Wisconsin

On September 20, 2026, Japanese condiment maker Kikkoman held an opening ceremony for its third U.S. production facility in Jefferson, Wisconsin. The plant began operating that day and is slated to start shipping soy sauce in October. Production capacity is planned at roughly 4,000 kiloliters by March 2027, with the site equipped for future multi-product output such as teriyaki and ponzu sauces. Honorary CEO Yuzaburo Mogi, President and CEO Shozaburo Nakano, and senior executive Osamu Mogi attended, alongside local officials.

Kikkoman established its first U.S. plant in Walworth, Wisconsin, in 1973 and added a second facility in Folsom, California, in 1998. The company now holds about 60 percent of the U.S. household soy sauce market, a share that has been stable for decades. North America accounts for roughly 70 percent of Kikkoman’s overseas soy-sauce revenue, making the region the cornerstone of its international business.

The Jefferson site represents a planned USD 560 million investment over ten years, a figure disclosed by the company. The plant’s output of 4,000 kiloliters will augment Kikkoman’s capacity ahead of the first October shipments. On September 19, 2026, Kikkoman stock closed at JPY 1,385 on the Tokyo market, within a 52-week range of JPY 1,314 to JPY 1,694 and a trading volume of 1,989,500 shares, according to market data providers.

At a pre-ceremony press briefing, Honorary Chairman Mogi noted that the number of soy-sauce consumers in the United States remains low and expressed hope that the market will expand further. He emphasized the company’s long-term intent to meet growing demand across North America.

Analysts note that North American sales are projected to rise 30-40 percent over the next decade, underscoring the strategic weight of the new plant. However, the market faces increasing competition from low-priced Chinese manufacturers, which could pressure Kikkoman’s dominant share.
