Is it possible for foreigners(european) to find job in Japan?

Question:

Any job.(not some kind of high-salary-paying job) since i haven't been to college, but i understand japanese language very well.
What are the conditions?

Answer:

No college, no work. Well, unless you are from a country where you can get a working holiday visa. But even then there is a time limitation, both on how much you can work and how long you can stay. Without a degree, no job. And with the current economic situation what you will be qualified to do is going to be in competition with Japanese applicants. Doesn't matter how well you speak Japanese in such a case, the Japanese applicant is going to win.

EDIT: Giogio's idea, well, that dog don't hunt. You'd have to have a visa to work in a hotel and I doubt any hotel is going to hire you with a working holiday visa. In fact, one of my students went to college. Spoke English quite well. Had a degree. Started work in a hotel. Starting position? Waitress in the restaurant.
