Kikkoman stock is drawing attention after the company opened its third U.S. plant in Jefferson, Wisconsin, on September 20, 2026. According to Japan Times, the site has already started operating and is due to begin shipping products in October.

Production starts in Wisconsin

The new plant is scheduled to produce about 4,000 kiloliters of soy sauce by March next year, according to Japan Times. The report also says Kikkoman products account for about 60 percent of the U.S. household soy sauce market.

That makes the new facility more than a symbolic opening. It is tied to a market where the company already has scale, and it adds capacity before the first October shipments begin.

North America remains central

According to Livedoor News, Kikkoman said North America generates about 50 percent of sales, while U.S. soy sauce sales are expected to rise 30 percent to 40 percent over the next 10 years. The same report says the new Wisconsin plant involves a planned investment of USD 560 million over 10 years.

The combination of 4,000 kiloliters of planned output, a 60 percent U.S. household share and a USD 560 million investment gives the opening clear strategic weight.

Stock level matters

Kikkoman stock closed at JPY 1,385 on the Tokyo market on the last completed trading day, with a 52-week range of JPY 1,314 to JPY 1,694 and volume of 1,989,500 shares, as quoted by market data providers on September 19, 2026. For investors, the new plant now sits beside the more important question of how quickly North American demand converts into earnings.
