Company history

The succession went badly. A president backed by the founding family lasted fifty days, and franchisee morale fell fast. In December 1998 Sakurada Atsushi — the founder’s nephew, then the director responsible for sales — was asked to take the top job at a board meeting the following day. He spent the night alone in the grounds of a temple in Ikegami and accepted, he later said, out of thought for his uncle. His first stated target, flat same-store sales for the year to March 1999, was missed. As emergency repair he chose a barrage of new products — fourteen in 1999 alone, against one or two a year previously — and the chain’s first celebrity television advertising. Same-store sales still fell. The year to March 1999 brought revenue of ¥61.0 billion and ordinary profit of ¥4.5 billion: the first decline in both since founding. Worse, the flood of new items clogged the kitchens, and a ¥190 value burger aimed at price-conscious younger customers held no surprise against McDonald’s at ¥130.

The real work was rebuilding the store network. Sakurada Atsushi identified the core problem as the widening gap between stores in location, floor area and staff quality; he sorted outlets into types matched to their market and rebuilt them from the fittings and the menu outward, and said openly that he would part company with franchisees who could not meet the standard. After visiting several hundred stores himself, he chose chain quality over chain size — owner numbers peaked at 693 in fiscal 1997 and fell thereafter. In 2003 the company put its cook-to-order advantage behind a deliberately expensive line, the Nippon no Burger Takumi, drawing a line between itself and the price war. Headquarters revenue nonetheless kept shrinking, from ¥72.1 billion in the year to March 2002 to ¥58.7 billion two years later, and early adoption of impairment accounting produced a ¥11.2 billion write-down and a ¥7.3 billion net loss in the year to March 2005 — after which, with the bad assets cleared first, the following year returned a ¥1.1 billion profit.

From there Mos pushed upstream into its own ingredients. It took a stake in the farming company Sungraise in February 2006 and went on to form joint ventures with growing regions — Kumamoto in 2013, Hokkaido and Shizuoka in 2014 — while a capital and business alliance with Duskin, the franchisor of Mister Donut, followed in February 2008. For a chain that sells fresh vegetables as its signature, working directly with producers stabilised both quality and supply. Overseas it returned to Asia: Hong Kong in October 2006, Thailand in March 2007, South Korea in February 2012. Domestic same-store weakness and store closures ran on into 2008 and the business press wrote of drift, but a strategy anchored on product quality eventually showed up as a rising average check; a price revision in May 2015 helped, and by the year to March 2016 revenue was back to ¥71.1 billion with ¥3.8 billion in operating profit, on a domestic network of around 1,300 stores.

In June 2016 the presidency left the founding family for the first time: Nakamura Eisuke, a career legal and general-affairs man, took over, and Sakurada Atsushi moved up to chairman. A chain that had always been led on philosophy was now run by a practitioner of contracts and governance, and the business press framed it as the real test of life after the founders. Under Nakamura the product and price mix was reworked, and the year to March 2017 delivered ¥70.9 billion in revenue and ¥4.7 billion in operating profit.

The crisis came immediately after. In August 2018 twenty-eight people who had eaten at nineteen Mos Burger outlets across the Kanto and Koshin regions were infected with enterohaemorrhagic E. coli O121. On 10 September the company published an apology disclosing a three-day suspension order against a franchised store in Ueda, and on 14 September set out chain-wide infection data and countermeasures; a second store, in Chino, Nagano, was also suspended for three days. Even after voluntary closures, disinfection and a full hygiene review, customers were slow to return. With the lost traffic came compensation payments to franchisees, and the year to March 2019 fell to ¥66.3 billion in revenue and ¥0.5 billion in operating profit, with a ¥0.9 billion net loss — the first full-year loss in eleven years, and a painful one for a chain whose entire proposition was food safety.

The pandemic, oddly, helped. Stores concentrated in residential and suburban locations, with takeaway already central to the format, gained from the shift to takeout, drive-through and delivery; combined with closing loss-making outlets and ¥1.2 billion in subsidy income, the year to March 2021 grew in both revenue and profit, and the following year reached ¥78.4 billion in revenue and ¥3.4 billion in net profit while much of the restaurant trade struggled. Self-checkout and cashless payment went in over the same period. Then input costs exploded: even after a price revision in July 2022, raw material inflation outran assumptions and overseas impairments compounded it, so the year to March 2023 recorded ¥85.1 billion in revenue with operating profit all but erased and a ¥0.3 billion net loss. Raising prices carelessly costs customers, so the response was to hunt procurement savings while pricing at a level customers would still read as value.

The prices stuck and the customers came back. The year to March 2024 delivered ¥93.1 billion in revenue and ¥4.2 billion in operating profit, and the year to March 2025 ¥96.2 billion and ¥5.2 billion — a record for the second consecutive year, with the operating margin back above 5%. The pricing method was described as gradation: three tiers from an affordable “regular” range up to a “super premium” one, reconciling higher prices with satisfaction rather than trading one off against the other. The company moved to the Prime Market in April 2022, and in May 2025 published a 2025–2027 medium-term plan that replaced a 30% dividend payout guide with a 30% total return including buybacks. Overseas the chain now spans nine Asian countries and territories, including the Philippines from February 2020; in Taiwan, the largest market, a new plant comes on stream in June 2026, while Hong Kong, Singapore and Thailand take the rest of the focus. Through fiscal 2027 the plan is consolidation — closing unprofitable stores and lifting existing-store earnings — with recovery targeted from fiscal 2028. The 2.8-tsubo stall at Narimasu has become a Japanese-born hamburger chain looking for its growth in Asia.
