1. Moe
Know what the fastest-growing side of the Otaku market is? Moe. The cutesy, adorable genre of manga and anime focused on barely legal heroines has taken over markets in Japan. Perhaos the most famous character to spring out of this super-genre is Vocaloid avatar Hatsune Miku, who seems to recently have dethroned "My Little Pony" in the comprises-75%-of-deviantart-posts department. You can bet it has bled into video games as well. Take the Touhou Project, a media franchise that grew out of frenetic top-down shooters that epitomize the term "Bullet Hell". The games are commonly regarded as some of the most intense examples of the genre...and all of the playable characters are adorable little girls instead of, y'know, spaceships. It doesn't take much to realize why the genre has yet to catch on in the West: It has undeniably creepy vibes. Idolizing wide-eyed fifteen-year-old girls is exactly the stereotype Western fans of Japanese games and anime try to
avoid. Here is some Moe you don't have to be ashamed of, though: Hatsune Miku fighting Mechagodzilla.
