Once again, we see that the Japanese are mindful about what goes on in the bathroom, and they’ve found ways to minimize any reason to be ashamed. Take a look at this panel of buttons in this public restroom. There is one button that shows the word “Privacy” so that if you don’t want anyone to hear what’s going on inside the stall while you’re there, you have the option to press that switch so that it’ll make other sounds again to diminish what’s really going on inside your stall.
