Can you please elaborate on Seoul VS Tokyo?

I've seen the work culture (non programming) in both and as far as my friends go.. I have a VERY difficult time seeing my korean friends vs my tokyo friends.

As far as compensation, I'm not sure about Seoul but Tokyo wages for software is very low I've found.

You'll find many startups in Berlin, anything else not so much. Try München, Hamburg, Frankfurt and Stuttgart if you want a good wage and interesting work.
