What makes you think your culture's not?
I came home early from a party tonight, because I was enervated by the predictability of the foreign staff, who outnumber the local Japanese. In fact, the most interesting staff were those from a certain SE Asian Catholic archipelago-nation, who try much less hard to be 'individual' and come off the better for it.
The Anglophone staff are going to talk about: how much they drank, or where they are going on vacation, or (if women) how nobody will date them in Tokyo, or how crazy the Japanese are (matter of perspective). Not a tenth of them have an idea of their own, or even from a book rather than a TV show.
Walked out on good drink and food, and much younger women of various complexions, and am having more fun typing this. God, I am turning into a curmudgeon.
