If you've visited Japan before, you'll undoubtebly have encountered all the fancy toilet technology that has become more common place here over time. Last night I ran into a new one. The restaurant bathroom was equipped with a device that would generate the sound of running water when it detected a person within a certain proximity. I thought it was a sound designed to help people "get on with it" so to speak and eliminate line ups. Turns out that it is something to mask the sounds of using the toilet and it's way more common in women's bathrooms than men's.
