Company history

Cosmos began in 1973 as a single small pharmacy. Masaaki Uno, a pharmacist who had studied at the Tokyo University of Pharmacy and returned to his home town of Nobeoka in Miyazaki Prefecture, opened a 66-square-metre shop called Uno Kaitendo. For two decades he had no ambition to change the trade: he ran a handful of small neighbourhood pharmacies as a sole proprietor, and even after incorporating as Cosmos Pharmaceutical in 1983 the sales floor stayed 66 square metres. The first twenty years were a long, patient run-up — a local druggist who did not yet reach for a new kind of business.

The turn came in December 1993. In the prefectural capital of Miyazaki City, Uno opened a 600-square-metre store and began building out multiple outlets in earnest. Under one roof it carried medicines and cosmetics alongside food and daily necessities — a clear proposition that a household could buy its everyday consumables in a single trip, inside a small catchment of ten to twenty thousand people. Rather than nurture a few star stores, Uno standardised every outlet; he fixed a 1,000-square-metre format in 1999 and a 2,000-square-metre one in 2003, and settled on suburban residential areas rather than city centres. What emerged was a format of Cosmos’s own — the small-trade-area mega drugstore.

Price was the other half of the design. Influenced by regular meetings with Hidejiro Fujiwara, then chairman of the apparel chain Shimamura, Uno judged that the loyalty-point scheme he had pioneered in 1994 rewarded price-sensitive shoppers who stocked up on bargain days while penalising the loyal customer who came every day. So he moved ahead of the industry: he scrapped daily bargain sales in 2001 and abolished loyalty points altogether in 2003, converting fully to everyday low prices. The timing was deliberate — he absorbed the short-term drop in sales while still private, so that after listing investors would see only the gains. In July 2004 the chain completed its coverage of every prefecture in Kyushu, and that November it listed on the TSE Mothers market — thirty-one years after the first small pharmacy.

Cosmos stepped outside Kyushu for the first time in March 2004, opening in Yamaguchi — and the way it did so defined the next fifteen years. Uno did not leap to distant big cities; he connected one new area at a time to the outer edge of his existing logistics zone, letting the network bleed outward like ink. Yamaguchi shared a daily life-sphere with Fukuoka and was easy to reach with the existing distribution network. Repeating that he would topple over if he rushed into Tokyo before his base was firm, Uno kept to the order — Shikoku in 2005, Hiroshima and Okayama in 2007, the Kansai region in 2010, Chubu in 2015, Hokuriku in 2018 — one prefecture at a time.

That the same store format worked region by region settled an old doubt. Sceptics had said the small-trade-area mega drugstore succeeded only because of Kyushu’s peculiarities; the unbroken run of results across Chugoku, Shikoku and Kansai disproved it. Everyday low prices and one-stop buying of daily goods were accepted whatever the catchment. The chain that had 193 stores and $903M (¥105bn) in revenue when it moved to the First Section of the Tokyo Stock Exchange in 2006 had grown past 850 stores and $5.1B (¥558bn) by the year ended May 2018.

Succession proved harder than expansion. In August 2017, Uno — then seventy — moved up to chairman and named not his eldest son but Futoshi Shibata, a long-serving corporate-planning executive, as president. After a downward revision to full-year results, Shibata left the post after only ten months. In June 2018 the presidency went to Hideaki Yokoyama, aged thirty-seven, who had risen through the field from store-area manager to head of sales. The ten-month handover from a planning man to a field man was itself a statement: at Cosmos, the instinct for merchandising, store openings and store operations sits at the centre of management.

In April 2019 Cosmos opened its first store in the Kanto region, by Hiroo Station in Tokyo’s Shibuya ward; associates say Uno was glad to have lived to see it. Two months later the chain passed 1,000 stores nationwide, and in the year ended May 2020 it caught the pandemic’s stay-at-home demand to post revenue of $6.4B (¥684bn) and record profit. The Kyushu-born format worked in the country’s largest catchment from its very first year. The pace of new openings then shifted to another gear — 78 stores in the year to May 2021, 120 the next year, and a record 139 in the year to May 2024 — the logistics network and standardised operations built over twenty-five years in western Japan transferring intact to the east.

In the year ended May 2025, consolidated revenue reached $6.8B (¥1.01tn) — making Cosmos the first drugstore chain in Japan to cross ¥1 trillion on self-built store openings alone, with no M&A in fifty-two years, across 1,609 stores. While rivals merged — Matsumotokiyoshi with Cocokara Fine, Tsuruha with Welcia — Cosmos trained its own people, chose its own sites and built its own distribution. The self-reliance had a price: interest-bearing debt rose to $286M (¥43bn) as land purchases were brought in-house, and the gross margin fell from 22.5% at listing to 19.5% as food grew heavier in the mix, held in balance only by cutting the SG&A ratio by a similar amount. What did not fade with scale was the consistency of the proposition — everyday low prices and one-stop daily shopping — carried unbroken from a single Kyushu store. In January 2026 the company announced a move into hotels, a fresh test of how far it can keep expanding without buying anything.
