There was a lot of interest in my Japanese Toilet post a few days ago. I just have a few things to add. The buttons with the music notes aren't for music. That button activates a loud flushing/water sound, so no one else can hear any other sounds coming from your toilet stall. Another curious thing about Japanese public toilet stalls is that they always go down to the floor, so there is no chance a child in the next stall can look under the divider into your stall. Many foreigners are surprised by Japanese high tech toilets, as this hilarious Mr. Yabatan video shows. He is VERY surprised!
