text: what do you need to major on in order to be a manga artist?   i'd try graphic design, visual arts, take some courses in japanese culture[hey it couldn't hurt ;-d] and anything that teaches you how to capture the feelings of real people, real things in a stylized manner would get you there.   i'm sure you don't need to major in anything.  you need to have a background in creative writing or just be creative enough that a publisher like viz wants to buy your stuff.  the same thing will apply to the visual aspect.
