>>35088763 that he doesn't think Japanese people are racist, they're just so not used to black people they get kinda weirded out when they see one. It's one of those things that's a bit hard for modern day Americans to wrap their heads around, since they see people of all kinds of races on the street every day and just don't think about it.
This is also why he thinks it's a good thing for him to be a host on a popular children's TV show like this, since it makes modern kids more accustomed to the idea of blacks and more likely to just see them as average people.
