I've been asked several times about why are there those birds chirping sounds at train stations here in Japan . The reason is the same as why you see those yellow blocks on the ground at train stations and on walkways in Japan . It's an assistance guide for visually impaired people . Those yellow blocks assist blind people with white canes to walk around , indicating when they can keep walking or pay attention to any dangerous situations . The birds chirping sounds are an audio clue that the person is either close to a train station exit , a stairway or a ticket gate . In the video bellow , I was at Tokyo's Yurakucho station , and you can hear the birds chirping sounds when close to the stairway , that also happens to be next to the ticket gates and the station's entrance . I didn't edit the video bellow , so consider it a raw cut , just for illustration purposes . Sorry for the poor quality of the narration .
