Sorry for the dumb question. If you don’t embrace any other cultures or languages except your own country, then just say country.
I will never be a “Norwegian Norwegian” as I wasn’t born or raised in Norway. I’m American, so my neighbors would be Canada and Mexico.
However, my cultural neighbors would be Sweden, and Finland I guess. I’m not a true Norwegian, for the record, but we embrace our heritage a lot and have been raised around videos of the language since I was little but didn’t actually remember anything so I’m learning more.


Don’t forget about Tobler’s first law of geography.
Cultural patterns will generally follow migration of people, which will largely be localized, but of course there are exceptions in which case you can get some interesting blends.
This would have worked way better centuries ago. Now, anything with a coast is a bit of a surprise bag.
Australia is far from England, and NZ is literally antipodal to Spain which is close, but they’re pretty English and not very Papuan or Indonesian.
