大戸屋 is pursuing a strategy of expanding into food courts, adapting its traditional model for smaller-scale operations while preserving the core of its set-meal offering. After a family dispute and hostile acquisition following the founder’s death, the company has recovered its performance and is now targeting growth under a new management structure.
When opening food-court locations, 大戸屋 is not simply downsizing its traditional restaurants. It is changing its operating model to enable smaller teams to run the sites, including through the use of central kitchens. At the same time, it is maintaining its core product, set meals, and pursuing initiatives to satisfy Japanese consumers, who value changes in flavor.
The strategy is also reflected in the company’s performance. Comparing 2019, before the acquisition, with the latest figures for 2026, revenue increased approximately 1.4 times, from ¥25.7 billion to ¥37.0 billion, while operating profit grew more than fivefold, from ¥400 million to ¥2.1 billion. The operating margin also improved from 1.6% to 5.8%.
Following a family dispute triggered by the founder’s death, Tomohito Mimori (三森智仁), a member of the founding family, became the new president in June 2026. This is being positioned as the company’s third founding. The hostile acquisition led the founding family to decide to sell its shares to コロワイド, and the company is now pursuing a turnaround under a structure that also has overseas expansion in view.
As costs rise and labor shortages intensify in the food-service market, 大戸屋’s current model is vulnerable to these changes in its operating environment. Backed by the organizational strength of its affiliation with コロワイド, however, the company is pursuing change while seeking to grow without compromising the value of its set meals.
