The chime used in Japanese schools is based on the Westminster Quarters melody, the same pattern associated with clock towers in London. School systems adopted the softer musical signal in place of a traditional buzzer, and it became a daily sound for generations of students. Through anime, dramas and films set in schools, international audiences learned to associate the four notes with Japanese classrooms even without explanation. Clips of the bell now circulate on soundboards and in editing libraries, where creators use it as instant shorthand for school life, nostalgia, and routine.
