I have family members in both Korea and Japan. Planning to work in one of them. However I decided on Japan even if it's hard to get in.
Why? Because Koreans discriminate SEA and calling us darkies or something. Wont even talk to me or the other dark skinned foreigners that went to the eyeball. They only give importance to white men.
Only Koreans who have successfully adapted to foreign countries are the good ones.
Japanese people however are the most polite I've known. No pressure about make up or fashion. Laid back (apart from work) and most of the people there around my age are studying various languages. Spanish, French, Arabic, etc. It was fun
