Competitive Landscape
Lopia Accelerates Expansion as Aeon Group Deepens Digital Engagement
Supermarkets remains a highly fragmented channel, with a structure defined by strong regional chains and only a handful of operators, such as MaxValu (AEON Group), achieving nationwide reach. Over the period from 2020 to 2025, the market did not become significantly more concentrated, as shown by the continued presence of many regional leaders and only incremental changes in company shares among the top players.
Trial Holdings and Seiyu Combine Strengths for Urban Growth
The completion of Trial Holdings’ acquisition of Seiyu in July 2025 marked a pivotal development in the structure of supermarkets in Japan. This merger creates one of the largest retail networks in the country, blending Trial’s regional strength in Kyushu with Seiyu’s nationwide presence and enabling the group to pursue aggressive expansion in urban centres, such as Tokyo.

Country Reports Disclaimer
Supermarkets
Supermarkets are chained or independent retail outlets with a selling space of between 400 and 2,500 square metres and with a primary focus on selling food/beverages/tobacco and other groceries. Supermarkets may also sell a selection of non-groceries, but the product mix is skewed towards grocery items. Example brands include Casino, Kroger, and Tesco. Exception: In some markets, primarily the US, Australia and Hong Kong, there are grocery retailer brands that operate outlets with a selling space of over 2,500 square metres, but offer only a very limited range of non-grocery merchandise or none at all. These brands are included in Supermarkets.
