Heading back to the hotel. And I keep hearing these birds chirping in the station. But can’t see any birds. So I googled birds in Tokyo subway.

The birdsong in the stations is to guide the visually impaired. It lets them know where the stairs or escalators for the exits are. pic.twitter.com/j9aMnHcoqS
