From the literal translation of the word toku, meaning "house. In Japan, Otaku means somebody with an obsession. From anime, manga, vedeo games, computers, to things from train sets, stamps, spoons, ect.

In the 8o's, Otaku was used for a Japanese case where an obsessed fan murdered a voice actress for not sounding th way he invisioned his favorite character.

Otakus in Japan tend to be under-weight with poor hygen and little to no life outside of their obsession, i.e. only leaving outside of their home for their care or additions to their collection of what they are obsessing over. Thus, having their society look down upon them.

In the U.S., fans of anime and manga tend to mix up Otaku for "guru", or master. A large amount of the fans of products of Japanese entertainment tend to view Otaku as a good thing. Otaku, in the West, normally means "fan of anime/manga/video-games".

The "otakus" of the US. tend to be over-weight, have poor hygen, and have little to no life outside of their own obsession.

People in the U.S. tend to make jokes about "otakus" and their Western version of "Comic-Book Junkie" to live in their parent's basement while obsessing with their collectables.
I am such an otaku because I love manga's and Kishimoto-chan!

Yuu only leaves his house in order to get a new train set... He must be an otaku.

The Otaku had murdered the voice actress because he did not like her portrayl of his favorite character.

this word was originally used in japan to describe someone who enjoys anime and manga. the term later became derogatory when a japanese news station used it to describe a serial killer who had been a hermit and was obsessed with anime, manga, and doujn. When it crossed the pacific to America, otaku became a word popularly used to describe anime-con goers. the Japanese, who are always quick to pick up on American fads, soon used the phrase to describe a cool "geek chic" type of person, often found in the Akihabara district of Tokyo.

1. Japanese for "nerd."
2. A big anime fan. Unfortunately, the name has been disgraced thanks to the large majority of otakus being 240 lb, 30-year-old white men who don't have a life.

Otaku

A person who loves to watch anime and read manga and also admires the Japanese culture, but not to the point of denouncing their own, that would make them a weeaboo. Being an otaku is basically being apart of a whole new culture, an it's great! Just don't become a weeb.
"Hey, do you watch anime?" "Yeah!, I am an otaku, you?" "So am I!"

1. A Japaneses man-child.
2. A non-Japaneses who is obsessed with Japan and do stuff like watching Anime, reading manga and buying body-pillows They are similar to a weaboo however they have some major differences that set them apart. Otakus manage to stay in touch with their own culture while also respecting Japaneses culture and not look like complete asses while weaboos make them selves look like asses by acting Japanese even though they are clearly not Japanese which disrespects Japanese culture.
