There are a couple of words to mean a person who has no job in spite of not being a student such as ニート(NEET: Not in Education, Employment, Training). I already introduced 引きこもり[hikikomori] here. But I sometimes come across some similar words to this kind of thing, and assume such people have become a serious matter. That is why this kind of word keeps coming up.
Unlike 引きこもり or ニート, this word was born in 2ch. Surprisngly, 2ch bugs came up with this to claim themselves…that is 自宅警備員[jitaku keibi’in], or home security guard. As you know, people who dwell on 2ch are sitting at the desk and obssessed with the screen. So they sarcastically insist they are surveilling home. Their job is to keep their home safe, so they have to be at home. 自宅[jitaku] means home, and 警備員[keibi’in] means a security guard. Eventually it is equal to be a ニート…Havin said that, 警備員 sounds better than 引きこもり, no? ^^ It makes me laugh a bit. Come to think of it, jobless women(in other words, female NEET) can be called 家事手伝い[kaji tetsudai]. Ugh, I can’t put it into English. Housewife? Nah, they are not married. Not correct. Anyway, their job is to do household chores. But what if they don’t do it? 結局ニートじゃん！Know this is only for women. Jobless men at home end up being a ニート or プー太郎[pu-tarou].
Comparing to above, 自宅警備員 still sounds okay(?). And when they get kicked out of home by parents[雇用主, employer], they recieve 自宅警備員解雇通知[jitaku keibi’in kaiko tsuuchi] to mean a dismissal notice of home security guard. They are sacked, so they have to leave home…and where are they going?
Yes, they are headed to the internet cafe to stay. Taking a shower, grabbing a snack, and finding a day labor…they eventually stay at the internet cafe. From place to place, they are wandering…so they are called ネカフェ難民[nekafe nanmin] or an internet-cafe refugee. They don’t have a home, but wander from internet cafe to another. This is also a serious social matter.
Remember Nagisa Kaworu in Evangelion said 帰る家があるのはいい事だよ[Having a home to go is a good thing]? Umm, come to think of it where is his “home”? OMG, could he be a ネカフェ難民? Just kidding.^^
