I think you will be fine in Japan.

Don't think about it too much is my advice... if you get discriminated against then my advice would be to brush it off and dismiss whatever they have to say.

However my impression is that you won't get openly discriminated against... and if what Sangetsu says is true (about people discriminating in private) then you won't know anyway so no need to dwell on it right?
