Kikkoman Corporation, the world's largest soy sauce manufacturer, has marked the 35th anniversary of its joint venture with Uni-President Enterprises in Taiwan, a partnership the company now says will serve as the template for expansion into South America, South Asia and Africa. The anniversary comes as Kikkoman confirms it will maintain its established positions in North America, Europe and Asia while pursuing growth in markets it has historically underserved.

The company holds more than 30 per cent of the domestic soy sauce market in Japan, yet overseas operations account for roughly 80 per cent of group revenue, a reflection of decades spent building manufacturing and distribution networks abroad as consumption at home has slowed.

The Taiwan blueprint

The alliance that produced the Tainan-based Tong-Wan Company was formed in 1990, when Kikkoman and Uni-President Enterprises, then and now Taiwan's largest food manufacturer, agreed to a 50-50 partnership. The structure addressed a specific commercial problem. Export tariffs had made it difficult for Kikkoman to sell into Taiwan profitably, so the company began manufacturing there instead, bringing its brewing technology to a local operation. Uni-President supplied what Kikkoman lacked: an established logistics and distribution network built over years of operating in the Taiwanese market.

That division of labour has proved durable. The joint venture generated revenue of approximately $35.9 million in 2025, according to figures released around the anniversary, with growth recorded in each of the preceding years. Kikkoman executives have pointed to the venture as evidence that the model can be transplanted elsewhere, provided a suitable local partner can be found.

Replicating the model in mainland China

Kikkoman applied a similar framework in mainland China, initially concentrating on coastal manufacturing hubs before extending into inland first-tier cities as urban incomes rose and demand for packaged seasonings grew. The mainland expansion drew directly on lessons from Taiwan, including the preference for local production over imports wherever tariffs or logistics costs made exporting impractical.

Globally, Kikkoman now operates eight overseas manufacturing facilities alongside three plants in Japan. The overseas sites are positioned close to major consumer markets, including the United States, the Netherlands, Singapore and Brazil. North America remains by far the most valuable of these markets, generating around 70 per cent of Kikkoman's international revenue and underpinning much of the investment case for further expansion elsewhere.

Demographic pressure at home

The push into new markets is driven partly by conditions in Japan and Taiwan, where ageing populations, shrinking households and a decline in home cooking have eroded traditional soy sauce consumption. Fewer people cooking from scratch means fewer occasions for the product's principal use case, and Kikkoman has had to adjust its portfolio accordingly.

The response has included reduced-salt, organic and non-GMO product lines, smaller packaging suited to single or two-person households, and a broader range of specialised seasoning sauces aimed at consumers who no longer prepare meals in the traditional manner. On costs, the company has said it intends to absorb rising raw material and logistics expenses through internal efficiency measures in the first instance, treating price increases as a localised and flexible tool rather than a default response to inflation.

Beyond Asian cuisine

Central to Kikkoman's growth strategy is an effort to detach soy sauce from its association with Asian cooking specifically. The company has spent recent years promoting the product for use in barbecue marinades, salad dressings and other everyday Western dishes, aiming to establish it as a general-purpose seasoning rather than an ingredient reserved for particular cuisines.

The company, which traces its origins back more than three centuries, is also looking beyond condiments altogether. Kikkoman has research programmes under way in biochemicals, health foods and enzymes, areas it regards as offering revenue streams independent of its core seasoning business. Whether these ventures mature into significant contributors remains to be seen, but they suggest a company preparing for a future in which soy sauce, however central to its history, may no longer be the sole driver of its growth.
