They kind of look like an incorrectly installed urinal! When I was in Japan with "The Hip Shakin" Daddies" in 1994, the first thing we checked when we got to a venue was the bathroom, to see if it was western or weird. It's funny what you miss about home when you're travelling.

   Generally, you squat to use one of these, although Victor Hazen, our guide & translator, tells us he used to stand to use the ones on the train. The windows were low enough that if you were standing, you were fully revealed, but when you were travelling through the countryside, that was not a problem.

   The problem was that one time the train pulled into a crowded station before he had finished.
