Brillant asian horror-drama's you probably never heard from!

Ring (korean original)

Ring (Ringu) is Japanese, unless you're talking about "The Ring Virus" which is the South Korean remake.

Some other Asian horror films you might like:

• Bakjwi (South Korea)
  
• Chakushin Ari (Japan)
  
• Ju-On (Japan) - Note that this is Ju-On "The Curse", not Ju-On "The Grudge". I think they're all just titled Ju-On in Japanese, which makes it confusing. It's the first in the series and in my opinion it's better than Ju-On "The Grudge", but you might want to check out the whole film series.
  
• Sorum (South Korea) - While I don't consider it a horror film, it does have some tense/eerie moments.
