FamilyMart is one of Japan's largest convenience store chains, founded in 1973, and its stores use an electronic door melody to greet customers as they enter. The short tune became familiar far beyond Japan through travel videos, anime fan edits, and social media posts about visiting Japanese konbini. As clips of store visits went viral online, the chime turned into shorthand for the whole convenience store experience. Creators still use it today as an instant audio cue for arriving, shopping, or feeling nostalgic about Japan.
