Recently, rapid increase of TV programs related to Korean contents has been the important issue in Japan since Sousuke Takaoka, Japanese actor, criticized it. But, my mother says "Recent Japanese TV programs are so boring. Who watches comedians eating lunch at a restaurant anywhere? So, I take it for granted that Japanese TV programs are gradually replaced by Korean ones."
I don't know whether Korean dramas are interesting or not. But, it would be unreasonable that only Korean contents are disputed, despite the fact that foreign contents except Korean ones are frequently broadcasted.
