Great list! Here's mine for sure minus Taiwanese because I have yet to watch any! So I'll just do my top 5 for Korean and Japanese. The way I will list it will go from my #1 to my #5. lol.
Korean: Kim Hyun Joong! Hyun Bin, Philip Lee, No Min Woo, and Jang Geun Suk.
Japanese: Seto Koji, Nishikido Ryo, Yamamoto Yusuke, Mizushima Hiro, Okada Masaki.
The Korean choices for me were pretty solid and easy for me since I've been watching more dramas. Japanese, however, is a really old list since I haven't watched any new ones!
Also: this would be interesting to see for a female version of actresses!
