This sound is widely recognized as the entrance chime played in FamilyMart stores in Japan, which is why many people simply call it the Famima sound. It spread far beyond the stores through YouTube uploads, remixes and travel videos, where the melody became shorthand for Japanese convenience store culture. Its popularity lasts because the tune is short, clean and instantly place-setting, so even a brief clip can suggest a late-night stop, a city walk or a slice-of-life moment online.
