Nah, I wouldn’t live there. The language is the biggest thing for me. And while I could learn it, I’ve never wanted to learn Japanese and I’m already dedicating myself to French.
Would I visit it? Maybe, but honestly not likely. There are other things/places I’d much rather do/visit before Japan.
Sure, I like some Japanese food, but we’ve actually got some of the very best available here because we have an even larger variety/availability of fresh fish where I live. Most of the Japanese restaurants here are run by Japanese individuals and even they attest to better quality ingredients (namely, fish) here than in Japan.
So, it’s not like I’d be visiting Japan for the food. And I don’t collect anime/manga related items, so I wouldn’t be going there for that either. The culture stuff might be fun, but again, there’s other places much higher on the list that I’d like to see first.
The opportunity to work in Japan though? I’d do it if I were you, assuming you’re willing to learn at least a working knowledge/capability of the language. It’s a fantastic opportunity and you’d have a purpose for going there, which I think would be a lot more enjoyable than just visiting or going there on a whim.
