Why strip games from Japan?

Why not?

But seriously. There are a huge number of them, as you can see by the size of this site, though not all of them are or have been known for what they are to the hentai fanbase. Japan seems to have long held a fascination for games involving stripping, and even though there are many that don't originate from Japan, no other country seems to have the enthusiasm for them that Japan shows. So many have been published in so many forms in Japan that it almost seems like you can't find a game or type of game that some Japanese game company or doujin software circle hasn't incorporated disrobing a girl into. I happen to be a big fan of games like this, but the best and most games in this vein seem to come only from Japan.

Another reason is, games like this get lost in the multitudes of look/think/talk hentai adventures, which seem to be more popular in Japan these days. I have nothing against those games, as some I've found to be quite enjoyable despite not knowing a lick of Japanese myself, but not only are strip-the-girl games easier to get into and understand, I generally like them more.
