The point of the bird sounds is to help visually impaired people find the exit (notice it's always coming from where the escalator starts).

- sho 8y agoHm. Are you sure? I don't mean the repetitive "chirp" sound which is typical for guiding the visually impaired, most obviously at traffic signals. I mean actual birdsong recordings, played quite subtly at random intervals (ie, sometimes minutes apart). It would seem quite an impractical way to guide anyone. Anyway, my information is from a friend whose uncle works at Tokyo Metro, and has seen his fair share of jinshin jiko maguro. She was quite clear about the notion that it was an anti-suicide measure, and I believed her. I did only notice it on the Saikyou line.
