I've heard people described as ぬるオタ (ぬるいオタク) "mild otaku" as well as 超【ちょう】オタク "super otaku". My question is whether there is a sort of "general set" of these sorts of words (maybe similar to the prefixes like: super-, ultra-, mega- etc.), or whether what I have encountered is really just creative language use.

Are there some useful terms to describe a kind of "spectrum" of enthusiasm?

E.g. Low to high: ぬるオタ, (普通【ふつう】の) オタク, 超【ちょう】オタク , etc.

It has been suggested that gachi- "serious/diligent" may be on par or above chou-.

Edit: Even phenomena like "Okatu-dom" are perhaps best not described as a linear spectrum. We could theorize dimensions like (kakko ii > kimoi), (dedicated > casual), etc.

Thanks for any help!

    >gacchi I think your friend meant 「ガチ」. There's also「キモオタ」 :D (just to add a few to the list, I don't know their exact nuances)

  • @siikamiika I think you are right about gachi; I'll edit the question. Kimo-ota is also a good addition.

There is no such thing as an established "general set" of classifying the degrees of otaku, but both ガチオタ and ヌルオタ are commonly used.

ヌル- and ガチ- can be used as prefixes to modify other nouns. ガチゲーマー refers to a hardcore gamer, and ヌルゲーマー refers to a casual gamer. Etymologically, ガチ comes from ガチンコ, which is originally sumo wrestling jargon. ヌル comes from ぬるい, an adjective meaning "tepid."

Note that ヌル has a negative connotation (i.e., "He's not ガチ enough" used by people in the ガチオタ tier). Something like ライトなオタク/ライトゲーマー would sound neutral and safe (if used in the situation where using オタク is safe, of course)

超オタク is not something people commonly use. I can safely say someone who uses 超オタク is not a Japanese otaku :)


I don't know the technical jargon, but in common Japanese expressions, you can say:


  • 完全にオタク
  • ドオタク(=ド・おたく=the おたく=マジ・おたく)
  • 200%オタク


  • 多少オタクっぽい
  • オタクもどき

  • You mean the ド in ドおたく comes from the English "the"?

Here are some types of otaku, but as for degrees, there doesn't seem to be a general set.



  • short for アニメオタク, or anime otaku


  • short for アイドルオタク, or idol otaku
  • refers to fanatic groupies of Japanese idols such as AKB48

隠れオタク or リア充オタク

  • hidden otaku

  • people who appear to be quite an outgoing person, but actually are engrossed into idol groups or anime & manga.


  • short for キモいオタク, disgusting otaku


  • 「ぬるヲタ」とは、「ヌルい」(未熟な事、あるいは物足りない、浅い状態)のおたくの意味です。 
  • 言葉の概念としては、「なんちゃってオタク」(オタクのフリをしている非おたくの 一般人)とか 「ライトオタク」「ちょいオタ」「プチオタ」「ニワカ」 などに近い言葉で、  しばしば本人が自称する言葉となっているのが特徴です。Source


  • お金があったら衣食住生活費より漫画、アニメ、ゲーム、映画などに充てて生活の基準が趣味優先、一般のそれと乖離してる人。
  • これをやってなきゃガチオタじゃないとかは言ってる人の勝手な基準であって意味がない。Source


  • aka, "huge otaku", isn't really Japanese to say but can be understood.

On the other hand, the word オタク can be also used to describe people who have an enormous amount of knowledge about something.

For example, サッカーオタク means “soccer nut/buff”, and ラーメンオタク means “great ramen lover/expert”.

However, I found a Japanese Quiz that could possibly test your "type" of Otaku-ness: Quiz

    Although its meaning is straightforward, I personally haven't seen 超オタ or 超オタク used by real otaku.
