Kristen McQuillin has put up a project celebrating the Yamanote Line which is the main train that runs around Tokyo.

She also pointed out this site which is recordings of all the now boarding toons around the line. If you don't read Japanese, click on any link with the letters ATOS in them. Listening to the sounds I couldn't help but wonder if "You know you've been in Japan too long when listening to the Yamanote line songs is natsukashii (nostagic) and comforting" 😃
