In east asia in general they have less awareness about LGBT stuff and also less awareness about homophobia. Their masculinity culture is also less fucked up and it's common for guys to cuddle and stuff.

I think that since each major east asian country has their own script and speaks less English and largely avoided full colonization from the West are why homophobia isn't a hot button issue there. There's also many nationalist groups that oppose Christianity and it's influence vehemently, so the right wing culture is very different
