In Japanese, “otaku” (or オタク) means “geek, nerd, or enthusiast” (JED, Japanese-English Dictionary). In Japan, this could include anyone from someone obsessed with reading books, to ancient shogunates, to anime, and anything in between. It truly means nothing more than “nerd”. However, Western culture has adopted the word “otaku” to mean, specifically, anime otaku.

Visual Novel (n.)
Visual novels are one of the most unique mediums of Japanese entertainment, and the hardest to compare to Western media. Visual novels are often considered within the genre of video games, which is a bit of a misnomer because many of them are “read” more so than “played”. The closest equivalent to Western media is the choose-your-own-adventure book (no longer of much popularity), though they actually play out more like a mixture of an audio drama mixed with a manga. Although there are differences within the visual novel medium, most are “read” by clicking through dialogue and thoughts of the main character from the first-person perspective, accompanied by background visuals, character sprites, music, and sometimes basic animations, voice acting, or mini-games. Although the visual novel medium is viewed overwhelmingly in Japan as a carrier of the infamous R-18 eroge genre (pornographic dating simulators), there are many visual novels that are clean and well-written. Well-known examples of visual novels include Clannad and Narcissu.
