Kikkoman plans to expand its operations in India, South America and Africa, Yuzaburo Mogi, chairman of the Japanese soy sauce-maker's board of directors, said Friday.

Mogi made the comments at a ceremony to mark the 50th anniversary of the completion of a Kikkoman plant in Wisconsin.

Speaking to reporters Wednesday, Mogi said that soy sauce consumption is expected to increase as the population of those regions grows.

Kikkoman will promote sales there from a long-term perspective so that its products will take root in local food culture, he said.

He also said the company will diversify overseas operations to reduce its dependence on soy sauce and focus on soy milk, a product in which it has a high market share in Japan.

Kikkoman began full-scale operations in the United States in 1957. To reduce costs, the company built the Wisconsin plant. In 1998, it also began shipments at a plant in California.

The company controls about 60% of the U.S. household soy sauce market.
