Whenever I see microcosms of Japanese culture I am always reminded of how little I know. Like it seems odd to me that their ideas of tea parties seem (at least to me) firmly situated in western "royal" tea parties (ceramic cups, multi layered cakes and the like). I've also heard gender lines there seems to be a lot softer but lack an idea of the scope. That trans women (earlier chapter) expected them to be disgusted or freaked out despite the fact they were cross dressing (which I feel would likely be treated as more taboo in the west). Males are also presented as being unable to enjoy sweets, is that to maintain appearance or are hobbies/preferences that heavily gated.
I've lived in a few western countries (us, aus, uk) and visited Japan before but I still am finding difficult rapping my head around this. If anyone has reading material on this I would be interested, something explaining the situation and definition of sex in eastern countries.
