East Japan Railway, known as JR East, runs one of Japan's largest rail networks, and its stations are known for melodic departure chimes played before trains leave. Unlike a harsh buzzer, these short tunes are designed to be pleasant and easy to notice in a busy station. Travellers have long associated them with trips across Tokyo and eastern Japan, and clips of the chimes now circulate widely online among train enthusiasts, travel creators and people nostalgic for Japanese stations. That familiarity is why the sound still works as instant shorthand for Japan.
