Yeah, well, as far as I understand it in short;

If you wanna go to Japan for longer than a tourist stay (live there) you got four options;

* Marriage

* A company is willing to sponsor your work visa

* Study at an University (though I hear you can get student visas at other kinds of schools too, but not sure)

* Working holiday (If you live in the right country)

I'm sure there are more, less common, ones. But this is the main ones, no?
