I have this personal belief: They both have good Pop (because, well, Pop is a fairly broad genre); however, Japan has better Rock, and Korea has better Hip-Hop. Of course, it's not without faults, it's only a general concept. This is based only on my opinion.

I say this because I haven't noticed many successful rock bands in Korea (or ones with particular appeal to me), which is probably why C.N. Blue - who began their careers in Japan - was such a hit. The Japanese rock scene seems more refined, at the moment. And I've noticed more the influence of Hip-Hop in the Korean music industry... for example, the current trend of implementing the rap solo.
M-Flo's Verbal is one of my favorite Japanese rappers by language; he's Korean.



... But, as I said, I like most music, regardless.
Over-analyzing sometimes takes the beauty out of things.
