hi. its danny from Korea. may I ask a simple question? Ive been working for 7 years at web programming(ASP,JSP,PHP..). My wife is japanese. I may move to japan to live in 4 years. so I would like to get a job in japan befor I move to. What a big problem is I can't speak japanese.. even read too. that's really big problem.. don't you think so? I should learn Japanese from my wife. ^^;
You should understand some Japanese to achieve your purpose in going to cafe or shopping.
Since you have some time left, you can take Japanese course in Korea. (or learn from your wife.) It would help.Learn the basic Japanese.
In terms of jobs, one of the sites I can recommend is www.daijob.com. I think they have English page. I never got job from this service, but they seem to have lots of jobs. Good luck, and if others have suggestions to Danny, please post.
