Though not to the same extent, I get the impression that a good number of Japanese and Japan in general might be somewhat more Westernised than one realises. To me, the red flag’s that Japanese language does have a word to describe red hair which even encompasses the dull orange variety. (Language contact, people.) Some may even get influenced by Western stereotypes of people with certain hair colours.
As far as I’ve been to Japanese websites (there are also Japanese people concerned about paedophilia). Maybe not as much as I made it out to be. But I still get the impression that Japan might be somewhat more Westernised than one realises even if it’s not greatly so compared to let’s say Hong Kong and Singapore. The fact that even the Japanese enjoy American programmes make me think they’re not entirely immune.
The more I realise from hanging out at Japanese websites, the more I think the Japanese are far from being that isolated.
