don’t worry about it too much! I can’t pretend I have any insight into default cultural attitudes towards autism in specific, but what I do know for certain is that conversations re: mental health and neurodivergence in Japanese culture are better-established & more mainstream at this point than it would seem at this distance
overthinking as we all do, but it all leads back to some good communication. granted, it might be tricky with someone who doesn't speak your native language, but maybe writing it out or something could help. if your intention and attempt is well natured, i'm sure they'd appreciate it. and if that's the only "problem" you have as a roommate (not doing dishes, not cleaning, etc), then i'd say it's a pretty good deal lol.
you know how online we tend to create community spaces so we can find & relate to one another, and how that has basically turned into a whole subculture of Neurodivergents Online, which has in turn inadvertently served the function of spreading awareness beyond the confines of our social circles / slightly reducing stigma? very similar situation with Japan (source: a major cluster of my special interests tie back to Japanese subculture scenes. happy to elaborate on this if you want 🫡)
