I wouldn't, because I'm not a Weeb.
I'd like to do a lot more research first. Visiting/Vacationing sounds amazing, but officially living there is a whole other story. If I could get over the heat and humidity I've been hearing about, that's one big step for me personally; with a whole flight or so of them to conquer.
So far, so good. Everyone has been very nice and helpful to me. I'm in Namamugi near Tsurumi river. Pretty sweet to jog along in the morning or at dusk. Though I'm not in a "touristy" area, I'm just a train ride away to Akihabara. Besides my neighbor, who just went back to Canada, I don't have anyone locally to chill with, so I'm a loner over here. I also haven't gotten senpai/kouhai to notice me (hypothetically; they never exist).
I would but not the rest of my life probably 2 years
That place that has the weekly monster or robot battles.
I wouldn't live in Japan because from what I've read the country is extremely racist, especially to people who fetishize the Anime/Manga culture. Not to mention they have an anti-fat law, which means your waist cannot exceed a certain size or you could be fined big money. Their food and cartoons are a nice foreign import, let's leave it at that.
I would totally live there. I lived there for two years it was amazing i loved it! i hate living in america it sucks. :(
I hate working period :/
I only want to go there to see hot girls and buy some anime things then leave. Working in the USA sucks already and I heard Japan is worse. I'd rather not live there if it's that damn bad.
Honestly I would be lost as fuck haha.
Would visit annually most likely
