Mr.Brain just started. The cast seems impressive.. There's Kimura Takuya, Hiro, Kame from Kat tun(special appearance).. O_O
A good new jdrama is Smile! It has Matsumoto Jun, Aragaki Yui and Oguri Shun. Its a star stud cast and a pretty heart warming plot.
Some good J dramas are Nodame, Mr. Brain, Natsu no Koi wa Nijiiro ni Kagayaku, and Proposal Daisakusen
I loved Hana Yori Dango, Hana Kimi, Ryuusei no Kizuna, Kimi wa Petto, Proposal Daisakusen, Freeter Ie wo Kao, Maou... that's all I can think of as of now..
Easy. Watch the Gokusen series, 1-3 + the movie. I watched Hana Yori Dango, watching Ikemen Desu Ne. Rookies. Yukan Club. Practically most of the Johnny's Entertainment people acted in. ... Mr.Brain..
