Do you think non-Japenese peope can be manga illistrators?

of course! If given the proper training and exposure, even non Japanese can be expert manga illustrators.

I think that even non-japanese people can be a best manga animator. Because I think that being a manga artist is an ability and a talent. I love manga and anime and I think that Japanese manga are great but also other manga that non-Japanese do.
Japanese are a great creator of manga no question ask! Other nation like americans, Filipino, chinese, and so on... can a do a creat manga it is depends upon the story that catches readers/viewers attention.

Well i actually have friends from high school who could draw good manga just like what we see in the movies. I think with a little help from modern technology it wont be far before they could also make their own cartoons just like those anime we have been watching.

Of course, I mean, drawing manga is not limited to the Japanese. You only think that that is so because that kind of drawing was originally form the Japanese. But I think even people from other countries can draw manga. There's no rule that they can't:)

everyone can do it if they really put their hearts to it. given the right training and determination. anybody can do. it doesn't mean that even though that art is name and recognized after the Japanese, they are the only one who can do it. I must admit they really studied humans, motions and nature and simplified it into a technique. A technique that everyone can follow. try to find articles about how to draw anime in google and you will see how easy it is to apply them.:D
