[@Taeryn]Space Hungary would be probably a relevant as Space Scandinavia or Italy would be here.
Korea probably has a special place because in the story their war was a major event.
Also I can't see South America being more important than Italy, either.
Even Space Japan can vary depending on what happens to the world in the following centuries but yeah, they can be very important to this NRP and I bet a few people (who already tend to make not-Japans in space NRPs) are going to take that faction anyways.
