Hello.
Republic of South Ossetia changed name "Republic of South Ossetia
State of Alania" at 2017. To translate it 「南オセチア共和国・アラニア国」.

This is an excuse, but I didn't read this wiki page except in Japanese. From next time, I will combine changes in a small geographical area.

Thank you for your advice.
