I like "GEGEGE no KITARO" and "Ghost in the shell SSS" and "Onegai Mymelody" and....so meny more.
The MANGA that I was impressed by in these days are "Yunagi no Machi Sakura no Kuni".It got many authoritative prizes.
However, a thing translated into English may not be published because it is the tragedy which made an atom bomb a theme.
