This one dives deep into Okinawa culture, tradition and dialect. Recommended for hardcore Otakus only.

I disagree about this part. It's still just basic romance and humor, you don't need to be hardcore to enjoy it at all. Those of us who aren't hardcore might miss some stuff, but it's still completely fine even then.

I will say the subs are a bit rough in places, since it's trying to translate both Japanese and the Okinawan dialect at some points, but it's doable.

Speaking of specific cultures or regions, have you seen Hokkaido Gals Are Super Adorable?
