JDramas which are based on novels

Hey guys,
I want to collect some JDramas here which are based on novels/books. I like such dramas because they are kind of different compared to other Jdramas.

Taiyou no Kisetsu (http://mydramalist.com/japanese-drama/458/taiyou-no-kisetsu)
Byakuyako (http://mydramalist.com/korean-drama/621/byakuyako)
Ryusei no Kizuna (http://mydramalist.com/korean-drama/102/ryusei-no-kizuna)

If you know some more Jdramas please post them :-)
