My stepmom is japanese so i've been dealing with their customes and culture for around 18 years. I wouldn't say they are anymore racist than any other culture but as someone else stated they are very proud. They're proud to the point that i guess you could consider it ethnocentrism. I assume alot of this would have to do with their technological advances and what not. In any case its not a good idea to even consider a whole culture racist just do it on a case to case basis.
