I love Japan
but I'm also interested in South Korea and have been learning a lot about the Korean peninsula in general lately and their history is really sad
it's an amazing country though.
I also like China because of the martial arts, but not just because of that--China has such a long, impressive history and it had a lot to do with how other Asian countries developed--most Asian languages borrowed things from Chinese.
Thailand also seems very interesting, but I don't know much about it yet.
I'm going to research every Asian country I can
