Hi. I am 20 years old, and currently living in England. I am from South Africa originally, I have a South African passport. I do not have a British passport. I realy want to go to Japan in the future, but I have heard you (mostly) need some sort of degree to work/live there permanantly. I was actually planning on starting a university degree this year or next over here (the universities in England start in September). I would then come over to Japan after I've done it (4 years). But lately I have been thinking this. Why not go over to Japan and study at a university there and work/live there afterwords. But here's the thing. I do speak very little Japanese, just a couple of words and sentences. So I was thinking the following: I would go over to Japan and learn the language there for a year, and then study afterwards (in Japanese). I am confident that if I actualy learn Japanese in Japan, I will be near fluent after a year (or at least good enough to do a degree in Japanese). Anyway here are my questions:
Do you people think a year is enough to learn Japanese?
Are there alot of places that teach Japanese to foreigners?
Do you think I would be able to come over like I said?
How much would it cost for universty in Japan?
What month do the universities start over there?
If I came over like that, what type of visa would I need and what are my chances of getting one?
I'd realy appreciate any advice or opinions. I luckily have the support of my parents (I am working at the moment, and if I do come over I would save up enough money, but I could also borrow money from my parents)
So what do you people think? Can it be done? Any opinions appreciated.
