Looking at the porn section of my video rental store here in Japan, nearly all of the common clichés turn out to be false. Hentai anime, rape and bondage, as well as various fetishes are present, but only in comparatively small numbers. The schoolgirl section is bigger, but also not dominant. The largest section is that of AV stars, basically porn aidoru; the videos are all centered around one young (but not minor), good-looking woman performing (mostly) regular sex.
