Sound Princess

This is very interesting equipment in Japanese women's restrooms. So called "Sound Princess" is a special noise maker. It makes a water flush sound when women do the business by pushing the button. Japanese women don't like to be heard thier pee sound by others and used to flush water only to disguise their sound. Because it was waste of water, one big toilet company developed this equipment and it amazingly worked! When it was first installed, 1500 Sound Princesses saved over 500,000 dollars a year. Now, you can see them everywhere in Japanese women restrooms. I've never heard of it till recently, and I want to try it just for curiosity. Japanese women are sensitive with sounds. Sound Princess symbolize Japanese nature about their personal matters.
