If you have watched the anime, NHKにようこそ！[Welcome to NHK!], you must have heard of the term, 引きこもり[hikikomori]. NHK stands for 日本引きこもり協会[Nihon Hikikomori Kyoukai “Japan’s Association for Hikikomori”], not Japan’s commercial broadcasting, NHK, which stands for 日本放送協会[Nihon Housou Kyoukai]. Forgive me, but I do not know how English speakers say 引きこもり since I haven’t been able to find out the appropriate word. At any rate, 引きこもり means a person who stays indoors every single day even though they are not mentally impaired(some people are, though). Yes, the protagonist in this anime, Sato-kun is 引きこもり. He got expelled from university, and he doesn’t have a job…every day he stays inside his room, in such a secluded space.
There’s another similar term, ニート[niito “NEET”], which stands for Not in Education, Employment, or Training. The funny thing is that I haven’t heard this term in the anime because Sato-kun insists he is 引きこもり. Yes, 引きこもり has to keep staying inside whereas ニート can go out anytime, accroding to him. Actually, ニート is more common than 引きこもり since the press generally focuses on them. As I have said, 引きこもり means even mental people sometimes. Comparing to 引きこもり, ニート does not seem to mean mental people.
So I hereby introduce a few more terms those relate this kind of thing. First, it’s 廃人[haijin]. 廃[hai] means to scrap, abolish, or discard. 人[jin] means a person…so literally, 廃人 means a scrapped person. Speaking of 廃人, we Japanese say ネトゲ廃人[netoge haijin] to describe a person who is addicted to online games. ネトゲ is an abbreviation of ネットゲーム[nettogeimu “online game”]. I heard some people died somewhere in Hong Kong or Korea because they played too much with no sleep, no eating, nor drinking.
Speaking of online games, there’s オフ会[ofukai]. オフ[ofu] means off, and 会[kai] means an assembly. This means an assembly by online game players, bloggers, or online chat mates. Upon the same purpose or interests, such people get together in the real world. In other words, this assembly takes place when they’re NOT on. That’s why we say オフ会. I have seen this kind of thing at a pub. Several people were having a party…but the weird thing was that it seemed to be not lively. They looked so solemn! And they called each other by alias, not real names. It sounded like the characters’ names in Ragnarok or something like that. I bet they must have met for the first time. Besides, the title of episode 12 of Welcome to NHK! is オフ会にようこそ！[Welcome to ofukai!]. But you will be terrorized when you see the assembly…no no, I shouldn’t give you any spoilers in case you watch this anime.
One more thing, there’s a spin-off term of ニート; 社内ニート[shanai niito]. 社内[shanai] means inside a company. It means a person who doesn’t work at all in spite of being at company. Though they can get a salary! Is there this kind of person at your company?
