Professor Lump, an old-school PoopReporter from the days of yore, sent in this thoroughly detailed site about the toilets of Japan. "
Dave in Japan: Toilet Training" is an incredibly detailed guide to pooping in Asia's most prosperous country (and further proof that anyone named "Dave" is automatically a qualified PoopReporter).
While most PoopReporters are aware of the existence of The Squatter, and while a few of us have had opportunity to use them, I doubt that many of us are aware that there are numerous techniques. It's not just stoop-and-poop -- as
this site points out, depending on the strength and flexibility of your legs, there are quite a few methods to choose from.
The best part is -- Dave-san took the time to create computer generated models of the different ways of doing it. Scroll about halfway down the page, and prepeare to be amazed! (And be grateful the model isn't anatomically correct!)
