I'm sorry to hear about your bad experiences Auckland-san. Perhaps I am spared from such racism because I have a Japanese husband...? (eg, he books the hotels.....)
Or perhaps Japanese officals are more wary of g-men, because they do have a bad rep in Tokyo.....

I was nervous to meet his Granma though because her husband died in the war and thought she would be really sad/angry to meet a gaijin - but she was lovely and really down to earth ;)
