William Gibson, one of the originators of the 'cyberpunk' science fiction genre, used the term "otaku" in his 1996 novel "Idoru". The meaning given, from a Japanese-translation computer function used by a character, was 'pathological techno-fetishist with social deficit'. The character so described spent much of his time online in a multi-user domain and subsisted on Ramen-type noodles and canned coffee. Although by Japan's rigorous social standards a "loser", the character was well-mannered and good-hearted.
"The otaku guys at my last school were into, like, plastic anime babes, military simulations, and trivia. Bigtime into trivia." -"Idoru", William Gibson

Often used as an insult in Japan for someone who is obssessed with anime, manga, video games etc.

Used in western culture to identify who reads manga and watches anime. It is sometimes confussed with weeaboo-ism, in which said person has an infactuation with japanese culture, i.e. everything including manga, anime etc.
Otaku boy: Did you read the latest chapter of Naruto?

A term that is miss-used by both the Japanese and other countries.

In Japanese its the honorific of home. meaning the person is a shut-in. They also refer to a community that visit certain places such as akihabara, Tokyo train station, ect. Otaku in America and other places is a term to describe fanatic fans of a certain thing ,mostly anime. In japan there are also other types of otaku such as train otaku "IE train station", Bridge otaku, anime otaku, music otaku, ect...

In America people think that it is being used wrong, but in actuality its just being used in the alternative term.

In japan the term is sometimes refereed to as something really bad. But their is a growing population that take the name otaku with pride. Demonstrations are being held. ect ect...
EX. how can a train otaku be an "otaku" if he actually leaves his/her house to go look at trains.

EX. how can an anime otaku be and "otaku" if he/she goes out to cosplay shops, akihabara, and other social events such as cons, "maid cafes", where the person HAS to meet other people.

A Japanese slang word for someone who devotes so much of their time to a particular activity that it is detrimental to their social status; a nerd.
"What an otaku; sitting at home always playing Starcraft."
by The Legend Never Dies August 08, 2013
Someone (such as me) who has an extreme love and obsession with Anime, Manga, Japanese Video Games, Cosplay and anything that has to do with Anime in general.

As you may notice most people define Otaku as someone who has nothing else better to do with their life but sit at home and watch/do the things I have listed above. Which is NOT true. We Otaku have many things to do, wether it's watching Anime or stressing over if our Cosplay is going to get here in time for the next Convention/Expo, I can assure you it is over infinity times better than what most of the people that say those things do. Which is most likely sitting at home eating them selves to death because they wish they had something to do.

And to note that in a previous definition of Otaku, that person said that the word "taku" means home and that that links to THEIR so-called definition. If you know Japanese at all you would know that Otaku (おたく) means "Geek" or "Nerd", which clearly shows our (being us otaku) love for Anime, Manga, Cosplay, etc.

I made this to show my love for Anime and to stand up for the TRUE MEANING OF OTAKU!!!!!!! >:O
Yumiko: "So, how much of an Anime fan are you?"

Sayuri (me): "I am a MAJOR "OTAKU!!!!!!!" ^ ^"

there are several definitions of "otaku"

1) polite(correct) way of saying house
2) many people mistake the actual definiton of otaku when it comes to things such as "anime otaku" or "game otaku"
it used to be a insult but recently, the definition has changed to a more positive meaning, although the word can still be used as a insult, it is more commonly used as a compliment
Ex. anata wa computer otaku desu ne (your a computer otaku)

although it is unclear as to when the definition switched, many believe that it may have happened with popularity of animes and mangas going up

manga otaku
electronic otaku
anime otaku

Means "Nerd" in Japanese.
People who don't know it call themselves otakus because they love anime and they're addicted to it.
Like weeaboos,for an example,they love anime too much.

This isn't anything good if you're trying to use it when you know its meaning.

What it means is an Japanese Nerd.
He has been calling himself an "otaku" for a half year now. He still didn't realize at all it means a Nerd,in the Japanese genres.
