FamilyMart, Japan’s second-largest convenience store chain, has turned a simple pair of striped socks into a fashion phenomenon. The blue, green, and white socks, priced at 390 yen (US$2.44), have sold 40 million pairs since 2021, transforming the store into a lifestyle brand in the fiercely competitive conbini market.
The socks, typically found near store entrances, have become one of Japan’s most recognizable convenience store products. FamilyMart is now expanding its fashion line with items like matching bandanas for pets and their owners, aiming to grow beyond selling daily necessities.
To support this strategy, the chain has launched branding initiatives, including a recruitment campaign featuring pop star Lady Gaga. The move underscores FamilyMart’s shift from a quick-stop shop to a lifestyle destination.
