Jobs for non-native speaker with o/s tertiary qualifications

Hey guys,

I have been thinking about moving to Busan for a while to stay with my girlfriend and train Jiu Jitsu. From what I have gathered from various forums, the job market for foreigners pretty much revolves around education and the ESL teaching industry. 

However, since I am born in Sweden it seems that I won't be able to qualify for an E2 visa so I am currently looking at other options. One would be a working holiday visa (new agreement between Sweden and S Korea as per this year) or an F-2 spouse visa. 

I have a BA in Japanese Language and a MA in Journalism from an Australian university and would like to either teach at a university/public school or find a "normal job" working for a multinational company. 

What opportunities would someone in my situation have in Busan (or Seoul)? Or more specifically, what options I have, who (if anyone) would hire me, any legal implications and/or loopholes and any other advice that could help me get a realistic impression of what to expect.


Cheers
