In the past the major source for any Japanese anime or adult materials were either regular Japanese bookstores or newsstands, or in specialty book and comic stores outside of the Japan. With the rapid growth of the World Wide Web and the lowering of the price of desktop computers thus making them more available within the home, the internet is now the best source to find adult hentai galleries.
Hentai is the word used in Japan to describe any materials that have sex and sexual rations as the main theme or topic of the storyline. Japanese hentai is very sexually uninhibited and the art depicts explicit sexual images. Adult hentai galleries reflect this and the images within these galleries can be very extreme in nature.
Most of the images within these online galleries are computer gifs (pictures stored in graphic file format). There are both regular and animated gifs as well as CG (computer graphic) images and 3D representations. Many adult hentai galleries also include short animated videos and anime (cartoon) clips. Many of these galleries offer thumbnail images to allow the viewer to see several pictures on one screen and the website to conserve space on the webpage.
The subject matter of adult hentai covers a wide variety of topics and sexual fetishes, and for each fetish there is a website that will cater to it. The sexual theme can be light as in ecchi (soft porn) or rather intense as in tentacle rape or coprophilia (expulsion of feces during sex). The storylines can be about the everyday life of normal characters or can be based in science fiction or fantasy set in exotic locales.
No matter what the fetish or storyline, there is an online adult hentai gallery within a website that will contain either pictures, videos or both.
