Teach English probably..
Unlikely to get a job or visa in your field even if your Japanese was perfect.
Sorry

What are the major careers there in Japan

For foreigners?
Teaching languages.
Read all the info on work and visas here on the forum and watch the video.

Hi people,

I've read some conflicting information and want to clear it up - I have a Bachelor's Degree (Multimedia) but it was THREE years, not four. Many of the sites I've read say that you need a four year Bachelor's Degree.

Does it make a difference?

I always heard four years too...
maybe call the Japanese consulate in your home country..

i'm abit confused, i've worked in Japan for a year with working holiday. During my stay i met few guys who worked for ALT and other english schools, they had 2 year college diploma and their application got accepted. I read alot of forums and saw both comments about work visa can only be obtained if you have 3-4 years BA degree AND/OR at least 2 years Diploma. if someone has clear information regarding to this, I would really like to know more about it. Thank you
