Maybe because they’re both island nations with an isolationist culture, but there are definitely parallels to be drawn between the treatment foreigners get in the UK and in Japan. Growing up, being Polish was the identity others assigned to me and how they identified me and the main way in which I was described, and people make a lot of assumptions about me based on it. I used to get asked if I was Jewish a lot growing up because I have pretty stereotypically Slavic features, for example, and one time a teacher described me as “sallow skinned” after seeing I have an ethnic name on the school register.
