I remember my first visit to a Japanese toilet. I noticed all the buttons after I finished my business and stood up.

Wow! What do these do? I bent over the toilet bowl and pushed a button at random...

All Japanese models have a pressure sensor built into the seat so that no water comes out unless someone is actually sitting on the toilet.

That was decidedly not the case when I first visited Japan in 2001. The jet of water that hit the door to the bathroom was quite wet by the time I figured out how to shut the toilet off.

A bidet in a London hotel around 2003 managed to hit me in the eye. I was a clear metre from the bowl. A mistake you make once and then not again!
