Picture books from/about Japan and Korea

Hello all,
I'm looking for picture book from/about japan and Korea. I'm after (1) Books translated in English that are easily available but that are written or illustrated by Japanese/Korean authors/illustrators (2) books that are somehow culturally specific (and may or may not be available in English) (and these two criteria may not be mutually exclusive of course). Basically I want to learn more about Japanese and Korean picture books and am after recommendations for brilliant books that I might enjoy with my own kids.
Thanks in anticipation,
Zoe

You might check out Survivors: The A-bombed Trees of Hiroshima. This is primarily a book of photographs, but also includes essays on the folly of war.
