I find that Jdrama is extremely underrated compared to Korean and Chinese drama. I think the reason is the sentiments from Asian country about Japanese overall.

I don't know why but I think Japanese drama are more realistic and shorter than other two.

Really? I thought Chinese/Taiwanese dramas were the most underrated

but anyways... Japanese dramas are really fun but I do think they are a bit too short compared to Korean dramas. Speaking of J-dramas... There's this drama out called Tokyo Wankei (Destiny of Love) and it's about a third generation Korean who falls in love with a Japanese man. However, her father disapproves of their relationship because he wants her daughter to marry a Korean. It's really good.

I posted a thread on this so go check it out.

japanese dramas aren't very good, taiwanese do suck and chinese, but HONG KONG, and korean dramas are very good.

Have you watched them yet?

battle royale was an excellent jdrama
