One thing I haven't seen mentioned on topics regarding this phenomenon: Japanese gambling places(pachinko parlors) appear to be more loud and obnoxious than their Western counterparts.

I mean, it's literally* gambling, so both are supposed to be maximally obnoxious. There aren't supposed to be differences. Yet there appear to be.

And that makes me think that there might be just differences in dopamine resistance between two cultures or something. Like people just take higher doses. I don't think that'll be a crazy concept considering that typical ABVs of hard drinks vary by regions.
