There seems to have been much more previous discussion here about Nazi attitudes towards Japan than vice versa. However, I did find this: "How aware was Japan of Hitler's idea of an Aryan master race?" at https://www.reddit.com/r/AskHistorians/comments/3mi146/how_aware_was_japan_of_hitlers_idea_of_an_aryan/cvfb5mg/ , answers by /u/Orchideenpavillon
But more can be said, I'm sure. This is not to discourage follow-on questions, info, and debate, which are welcome.
