Learning Japanese doesn’t always have to be so technical! Japanese should be enjoyed as a language and as a culture. As much as people want to deny it, one thing that has always helped boost Japan’s popularity is it’s otaku subculture and its presence in the media. For this blog, we’ll talk about common Otaku words you should definitely know!

What is an “Otaku”?

This is quite a Western mainstream term used for people who are into Japanese culture, mainly anime and manga. Although this is the case, most people don’t know that “Otaku” also stands for another persons house (お宅) and metaphorically used as an honorific second-person pronoun. The mainstream one we use today (おたく/ オタク or, less frequently, ヲタク) first appeared in the 1980’s and have been used since then in Japanese and international media as a slang term for someone obsessed with Japanese popular culture. The term “Otaku” can be also used for an obsession for something else. You can say “Computer otaku”, “Game otaku”… pretty much anything can be paired with otaku as long as it is a hobby someone is close to obsessing over.
