I love Eita although I haven't seen all his dramas and movies yet (I'm excited to see them all)! I cannot choose which role I loved him the most. Hahaha. I was so glad to see a Stalker's Guide article of him here a few weeks ago. ^__^

I'm also very interested with anything with Haruma Miura in it. I especially loved him in "Taisetsu na Koto wa Subete Kimi ga Oshiete Kureta." 
I Like Miura Haruma (^_^) Yamapi is Awesome too!!
right now...i say Yamada Ryosuke! He is improved SOOOO MUCH, i really love his acting!
also I like Yamazaki Kento and Satomi Ishihara!
Kento Yamazaki & Masaki Okada
Kitamura Kazuki, Nagase Tomoya, Abe Hiroshi, Sakai Masato, Tsukamoto takashi, Sorimachi Takashi and more!
Recently I like Takito Kenichi. Although maybe it's more that I like the type of character he usually plays.
The one and only Masaki Suda
I really love Suga Kenta, he is the reason why I started watching japanese dramas. I just love him as Gaara and Hinata in the live actions.
I also like seto koji, he is so cute and at the same time hot. WHY are japanese actors so hot -.-
