I've seen alot of these drama already

Secret Garden is definitely hilarious to watch~
Hana Kimi is also another hilarious drama! Nonstop laughing~
You're Beautiful is a nice soft drama. I liked it alot. Emotional at times but still a really nice drama if I do say so myself~
My Girlfriend is a Guhmio is a slow moving drama in my opinion I haven't finished it yet. >.< But I do like the drama it is nice. It is really cute!~
I haven't seen 1 Litre of Tears or Densha Otoko, but I have heard a lot about them.
I never really had an interest in IRIS... Not exactly sure why...
I was suppose to watch Bad Guy but never really had the opportunity to... T.T
49 Days is definitely a tear jerker I've heard. I'm really hesitant to watch it because I don't like crying often at my dramas....
I haven't heard anything about Soul thoughhhh....
My friend showed me Yamato Nadeshiko Shichi Henge! Ohhh it was sooo cute and funny! I loved this drama sooo much!
I think my favorite Japanese drama would have to be Yukan Club though!!!! I was laughing soo hard!
