FamilyMart, a popular convenience store chain in Japan, is experiencing a surge in popularity among tourists, specifically for its socks. Favored for their unique designs and affordable prices, the socks have quickly become a must-buy for visitors. The trend emerged unexpectedly, with the surge of tourists choosing to purchase them as souvenirs or for personal use.

In Japan, convenience stores, or "konbini" as they are locally known, are far more than places to grab a quick snack. They offer a variety of goods, from food to clothing, and are deeply ingrained in Japanese daily life. FamilyMart's socks becoming popular among tourists highlights the international appreciation of the depth and variety of goods available in Japanese konbini.

In the US or EU, convenience stores primarily feature food and snacks, and they are not typically seen as shopping destinations for items such as clothing. The popularity of socks from FamilyMart among tourists shows the unique cultural difference of how convenience stores operate in different regions.
