I've heard there is some part of Japan that is hesitant of any "foreign medicine" and requires anything being introduced into the country to undergo their own Japanese studies because they think they have some sort of unique body that doesn't work like others but that sort of thing, like a lot of BS tends to mostly be the older generations. But since the older generations are still the ones who dominate politics (especially in a lot of Asian countries) they fuck up a lot of stuff that you would think they shouldn't.
