People don't regularly talk in trains in Japan. It's a form of respect to stay quite and just enjoy the ride. You can hear multiple sounds, just listen. This helps us sleep and we can think and dream about our time when we were there. Even if you've never been, it's just nice to hear the sounds. Enjoy!
This was recorded on a Zoom H8.
