It takes only the most minimal exposure to Japanese porn to understand that the Japanese sexual culture is very unusual to non-Japanese eyes. You may not understand much else, but you’ll understand that much very quickly.

Other little hints present themselves from time to time. Example: Japanese Kids Are Perverted. Excerpt:

Let me introduce you to a game Japanese kids like to play called “Kancho.”

Actually, it’s not so much a “game” as it is kids clasping their hands together, sticking out their first fingers, and shoving them up your butt. I’m really not joking.

You know, before we come to Japan, they tell us a lot of ultimately useless stuff. What kind of computer to bring, if our DVD’s will work, clothing sizes, that kind of nonsense. Nowhere, and I mean nowhere, in the 3-4 months of orientations did anyone ever mention that at some point, a Japanese kid may try to stick their fingers up our butt. That’s something I would have liked to know, personally.

It’s called Kancho, and just about any kid can be a Kancho Assassin. Even the sweetest little girl may be prone to jam her fingers up your ass the second you turn around. This happened to one of my friends, which just goes to show – don’t trust anyone. I’d say the little girls are the most dangerous cause they have natural ways of lowering your defenses.
