Manga is the genre of comic books created in Japan. Most of them you actually have to read right to left. You can usually find them next the the "graphic novels" in the book store with those creepy kids reading them.
Manga in Japan is geared toward a larger audience than comic books in the United States. It is geared toward many different people to young kids, teens, to older adults. Thats why there are so many different genres of manga. They are usually rated from all ages to adults only. So you can find young kids to your uncle creepy in this aisle of the book stores. Most of the people hanging out in the manga section are sad, lonely teens who have no lives outside reading manga and watching anime. The are usually wear hot topic clothing or wearing an anime t-shirt and/or discussing that awesome chapter of Naruto where he battles that one guy. In many high schools throughout the United States you can find Japanese clubs that surround their whole lives around manga and anime. They usually travel in pacts and you can spot these pacts because they usually wear Naruto head bands and usually have their faces buried in the books.
I'm not saying that Manga is totally uncool I'm just saying that fandom gets pretty creepy at times.
