You can go to youtube.com to watch Korean as well as Japanese and taiwanese dramas or you could go to veoh.com. You can also go to MySoju.com, and Dramafever.com. you also can go to kimchidrama, dramacrazy, epdrama and dramasub, etc. I recommend dramafever.com and kissasian.com the most.
There is an app called crunchyroll and they have lists of dramas including Korean ones you can watch also there is an app called viki and new dramas always being added. You can also watch on youtube, people have uploaded many dramas. Epdrama.com/mobile has a good selection of drama. There is also a app called 'Drama Fever' it works great with good quality! But the problem is the ads. =_=
I hope this helps:- mysoju.com- viki.com- veoh.com- dramacrazy.net- dramafever.com- kissasian.com
kimchidrama~
Try dramasub.com, however only 3 episodes are available. But it's a great site, you can also watch other Japanese and Korean dramas there.
It depends what kind of Asian dramas.. like there are Korean dramas, Chinese dramas, and Japanese dramas. One of the easy sites is youtube.com. There are more Chinese dramas than anyone kind. If you don't understand Chinese, you could always watch the English subtitles. There is Smiling Pasta, Hana Kimi, Romantic Princess, Bull Fighting, Magic Ring, Why Why Love, Devil Beside You, and many many others.* dramanuts.net, mysoju.comhas a lot. Depends on your taste, but I liked Full House, and Hana Yori Dango. =]. Also to find good Korean Dramas go to Crunchyroll.com and Dramafever.com, some of the best dramas I like are: My lovely Samsoon, Princess Hours, Goong S, and I Really Really Like Youboys over flowers is highly recommended.
