In order to live there legally and work there legally, one almost always has to have a degree from a university (4 year college). Japan isn't going to accept you apart from being a temporary visitor (tourist) unless you either have a student visa or a working visa (you need a sponsor). Why don't you ask the question in a forum where there are real people there, not filled with spambot like this one. Go to
Japanologic Forums • Portal and ask your questions. You'll get honest answers, perhaps not the answers you want to hear, but it will be real advice.
