For study purposes. I actually got into dramas accidentally when I started to watch them to help study Korean. However, perhaps because I'm awful at searching the internet, but I'm having trouble finding places to watch with the Korean subtitles which are invaluable for study. 

Viki has SOME of their dramas subbed.... but most of the time the Korean subs are only available for the first few episodes before they disappear. I was able to find the full korean subs for Healer and Goblin, but thats about it. 


However, this is a far tougher task for Japanese.... It seems Japanese content.... at least legally, is tough to access overseas. If there is any, literally any J-drama subtitles that you know I can get to study, please let me know! I'd also be interested in anime and movies too. Thanks!
