I live in Japan and have been around Asia. I can attest that despite all the melodrama, there is a lot of fact here. Some of it is outdated though. I've seen that sex museum in Toga. It still has some of those same dolls and attractions believe it or don't. Most of those live S & M shows in Tokyo have been discontinued though. They still exist if you know the right people that can tell you where. The religious healers are all over Asia. And some of these faith-healer types still have a following. This doc. focuses on the sex mostly though. And yes, you can still drink a glass of snake blood in places. Expect to pay about 50 dollars. Yes, I tried it once. Let's just say it's an acquired taste. The operation was VERY hard to watch. And it was NOT fake. That doctor is still working as a consultant in Singapore I believe. You need a strong constitution definitely...but I think it's worth a look.
