Biggest Supermarkets in Japan: Who Really Owns the Shelves in 2026

Japan's supermarket market is led by AEON and the Ito-Yokado/York-Benimaru duo, now majority-owned by Bain Capital's York Holdings rather than Seven & i Holdings directly, alongside regional heavyweights Life Corporation, Yaoko, Izumi, and Summit. This guide ranks Japan's biggest chains by revenue, store count, and format, sourced to each company's FY2025/FY2026 filings.

Most "biggest supermarkets in Japan" lists you'll find are quietly out of date on one fact that changed in September 2025: Seven & i Holdings no longer owns Ito-Yokado or York-Benimaru. That single restructuring reshuffles who actually controls Japan's second-largest supermarket footprint, and it's the kind of detail that matters if you're deciding whose door to knock on first.

Japan's biggest supermarket chains, ranked

AEON and the Ito-Yokado/York-Benimaru group have anchored Japan's supermarket sector for decades, but revenue, store count, and ownership have all shifted in the past 12 months. The table below ranks nine chains primarily by their most recently reported fiscal-year revenue among full-line GMS/supermarket chains. Where standalone revenue is not yet separately reported, as with the newly restructured Ito-Yokado/York-Benimaru group, it uses disclosed group scale instead. Fast-growing discount-format chains (Don Quijote/PPIH and Gyomu Super) are grouped at the end of the table regardless of raw revenue, since they compete in a different retail category. Store counts and format are noted separately since a chain's national reach and its per-store buying behavior don't always move together.

For scale: supermarkets took a 44.7% share ($86.4 billion) of Japan's $193 billion food-and-beverage retail market in 2024, ahead of convenience stores at 28.4% ($54.9 billion). This is per the U.S. Department of Agriculture's most recent Japan retail-foods report, which sources its figures to Japan's Ministry of Economy, Trade and Industry (USDA FAS, "Retail Foods Annual: Japan," Nov. 2025).

Methodology and data vintage: revenue figures reflect each company's most recently reported full fiscal year as of this writing (mostly fiscal years ending February to October 2025 or 2026, per each company's own reporting calendar). Store counts reflect the most recent figure publicly disclosed for each chain at time of writing (predominantly dated February to July 2025); where a chain's ownership changed mid-cycle, both the old and new structure are noted, and where a post-restructuring entity's standalone revenue is not yet separately disclosed, that is stated explicitly rather than estimated.

Which two retail groups dominate Japan's supermarket market?

AEON is the more straightforward half of the story: one holding company, ¥10.72 trillion in FY2026 revenue, and a multi-banner supermarket and GMS network (Maxvalu, Kasumi, Maruetsu, Kohyo) that operates in every prefecture. The other half used to be just as simple: Seven & i Holdings owned Ito-Yokado and York-Benimaru outright. That stopped being true on September 1, 2025.

Facing takeover pressure and a strategic push to concentrate on its 7-Eleven convenience-store business, Seven & i split off Ito-Yokado, York-Benimaru, Denny's Japan, Loft, and Akachan Honpo (29 companies in total) into a new entity, York Holdings, and sold a roughly 60% stake to U.S. private-equity firm Bain Capital for ¥814.7 billion (about $5.5 billion) (Bain Capital; Retail Insight Network; Supermarket News). Seven & i and the founding Ito family reinvested to hold the remaining stake as an equity-method affiliate, meaning Seven & i still has skin in the game but no longer runs the supermarket business day to day.

Masahito Uchino, who spent over a decade at Red Bull Japan, including six years running the off-premise channel as National Off Premise Manager and four years as General Manager, before serving as Executive Officer of Marketing and Sales at Ohayo Dairy Products and then Country Manager of innocent Japan GK, has watched this kind of consolidation from the vendor side for two decades. His read: national retail groups like AEON and York Holdings centralize category decisions at headquarters, so a new import typically has to clear a corporate buyer before it reaches a single shelf. Regional chains like Yaoko, Izumi, and Life still let store-level or regional merchandisers make the call, which is often the faster, if smaller-scale, way in for a brand without an existing Japan track record.

That regional layer is also where Japan diverges from a market like Australia, where Coles and Woolworths control the bulk of national grocery retail between them. Japan's two largest groups combined do not come close to that level of concentration: Yaoko, Izumi, Life Corporation, and Summit each post real regional dominance (Yaoko in Saitama and the Kanto region, Izumi across Hiroshima and western Japan, Life in Kanto and Kansai, Summit in greater Tokyo) without threatening AEON or York Holdings nationally. For a brand entering Japan, this means "get into AEON" is not the whole distribution strategy in the way "get into Coles or Woolworths" might be in Australia. Regional chains are a parallel, not secondary, path onto shelves.

How is Japan's supermarket landscape different from other Asian markets?

Three structural features trip up brands that assume Japan's grocery retail landscape works like its APAC neighbors.

First, the convenience-store overlap. Until September 2025, 7-Eleven Japan and Ito-Yokado sat under the same Seven & i Holdings roof, a level of channel integration that does not exist for Lawson or FamilyMart, which run their own distribution networks adjacent to, not integrated with, any supermarket chain. Even after the York Holdings split, the two networks retain overlapping supplier relationships built over a shared corporate history, which matters if you're trying to figure out whose buyer to approach first.

Second, depachika, the basement food halls of Japanese department stores (Isetan Mitsukoshi, Takashimaya, and others), function as a premium import channel entirely separate from supermarket shelf space. A product too niche or too expensive for AEON's mainstream aisles can still find real distribution through depachika, which the USDA's own retailer ranking lists Isetan Mitsukoshi among Japan's top 10 food retailers by sales (USDA FAS, Nov. 2025). That gives Japan a premium channel most market-entry guides for other Asian countries do not need to mention at all.

Third, and most consequential for a new entrant: none of the chains ranked above buy direct from a first-time foreign supplier. Japan's regional secondary-wholesaler layer sits between any manufacturer and any retailer's shelf, and getting that layer wrong is the single most common reason a well-funded market entry stalls. The three-layer distribution system is mapped in how Japan's distribution system actually works. Read that next if the ranking above raises the question of how to actually reach any of these retailers. Once you know which retailer to target, the next question is whether your product can legally reach that shelf at all. See Japan's food import and labeling requirements.

Discount and regional chains reshaping the market

The fastest-growing formats in Japanese grocery retail right now are not the national GMS chains. They are discount and regional players eating share from the middle of the market.

Pan Pacific International Holdings, parent of Don Quijote and MEGA Don Quijote, posted ¥2,246.8 billion (~¥2.25 trillion) in FY2025 (year ended June 2025) group-wide net sales, up 7.2% year-over-year, with sales at its discount chains specifically up roughly 12% year-over-year as inbound tourism drove tax-free purchases to new highs (PPIH FY2025 results; JapanIQ). The chain runs 655 stores domestically across Don Quijote and its sister discount brands (779 including its overseas footprint), and its jumbled-aisle, always-open format has become as much a tourist attraction as a grocery destination. That is a genuinely different customer acquisition model than anything AEON or York Holdings runs.

Kobe Bussan's Gyomu Super chain is growing even faster on a smaller base: 1,112 stores as of July 2025, up from roughly 1,084 nine months into its fiscal year, with quarterly ordinary profit up 74% year-over-year and full fiscal-year (ended October 2025) net sales of ¥551.7 billion, up 8.6% (Investing.com; StockAnalysis). Gyomu Super runs on a franchise-heavy, bulk-and-wholesale-adjacent model built for value-focused households. It is a format with no direct equivalent in many other "biggest supermarkets" comparisons.

Meanwhile, the regional chains in the ranked table above are not just surviving national competition; several are outgrowing it in their home territory. Yaoko posted 18.9% year-over-year revenue growth for its fiscal year ended March 2025, helped by the consolidation of regional chain Sendo Co. (DCF Model, Yaoko FY2025 results), while Izumi's FY2026 revenue climbed 8.6% on continued expansion across Hiroshima, Kyushu, and Shikoku (StockAnalysis). Neither chain is trying to out-national AEON. Both are betting that deep regional density beats thin national coverage, and their growth rates back that bet up.

Frequently asked questions

What's the difference between AEON and Seven & i Holdings' supermarket strategies?

AEON runs its supermarket business directly through a single holding company across multiple regional banners (Maxvalu, Kasumi, Maruetsu, Kohyo), giving it centralized buying power nationwide. Seven & i Holdings no longer runs a supermarket business directly at all. As of September 2025, Ito-Yokado and York-Benimaru sit under York Holdings, roughly 60% owned by Bain Capital, with Seven & i and the founding Ito family retaining the remaining stake while Seven & i focuses on its core 7-Eleven convenience-store operations (Bain Capital; Supermarket News).

How many supermarkets operate in Japan?

Japan's food-and-beverage retail market totaled $193 billion in 2024, with supermarkets taking a 44.7% share ($86.4 billion), the single largest retail-food channel, ahead of convenience stores (28.4%, $54.9 billion) and drug stores (11.2%, $21.7 billion) (USDA FAS, "Retail Foods Annual: Japan," Nov. 2025).

Do international F&B brands need a distributor to get onto Japanese supermarket shelves?

Yes, in nearly every case. None of the nine chains ranked above buy directly from a first-time foreign manufacturer. A regional secondary-wholesaler layer sits between any new supplier and any retailer's shelf, and that layer is where most first-time market entries stall. See how Japan's distribution system actually works for the full three-layer breakdown.

Which supermarket format is easiest for a new F&B brand to enter first?

Regional chains generally move faster than national ones, since Yaoko, Izumi, Life, and Summit still make category calls at the regional or store level rather than routing every new SKU through a national buying committee. National GMS groups like AEON or York Holdings can move real volume once a brand clears their vendor-onboarding process, but that process is longer and more centralized than a regional chain's.

Why did Ito-Yokado and York-Benimaru leave Seven & i Holdings?

Seven & i Holdings was under takeover pressure and chose to concentrate on its core 7-Eleven convenience-store business rather than run a diversified retail conglomerate. It split its supermarket and specialty-store businesses (Ito-Yokado, York-Benimaru, Denny's Japan, Loft, Akachan Honpo) into York Holdings and sold a roughly 60% stake to Bain Capital for ¥814.7 billion (about $5.5 billion), completing the transaction on September 1, 2025 (Retail Insight Network; Supermarket News).

Is Don Quijote considered a supermarket in Japan?

Not in the traditional sense. Don Quijote and MEGA Don Quijote are classified as discount variety stores, not supermarkets, though their food and beverage sections compete directly with supermarket aisles and their parent, Pan Pacific International Holdings, appears among Japan's top 10 food retailers by sales (USDA FAS, Nov. 2025).

What this means if you're trying to get onto these shelves

Knowing that AEON and York Holdings anchor the national tier, and that Yaoko, Izumi, Life, and Summit control real regional density, is table stakes, not a market-entry plan. Every chain in the table above sources through a distributor or a secondary wholesaler for a first-time foreign brand, and picking the wrong one of those, or the wrong chain to target first, is the difference between a six-month shelf placement and a multi-year one. GourmetPro's Japan retail-entry support puts F&B brands entering or expanding in Japan in front of local experts who've run commercial and retail relationships inside chains like these directly, including GourmetPro's Japan market-entry program, rather than leaving you to reverse-engineer the distributor layer from a ranked list. Before your next FOODEX Japan or trade-show trip, book a Japan retail-entry consult with someone who has already made the calls you're about to make.
