Downloaded this map mod today. Have been wanting an updated modern map for HOI2 for a long time. This completes my refuge seeking away from the horror of HOI3!
Some minor fixes if I may recommend:
1) The two islands south of Tokyo called Oki-mura is a mistake. That is Iwō-jima. Oki-mura is a town on Hahajima island, the second largest island that makes up the Ogasawara/Bonin Islands north of the in-game Oki-mura (still within the Bonin Trench, link in second recommendation). Renaming it to the local Iō-tō would be incorrect as that is what it was called pre-war and was not restored by the Japanese Government until 2007. The Americans only called it Iwo Jima because that was what the IJN mistakenly called it.
2) The Island south of it, Motoyama doesn't exist in real life. Consider taking it away. If it is possible, you might as well make one of the Bonin Islands accessible and call it Chichi-jima (

They had resources there that were used for the Battle of Iwo Jima, it was an important target for the USN to bomb, 25,000 troops surrendered there after the war, a much younger President George Bush senior was shot down there where other less lucky American pilots ended up as breakfast, lunch and dinner for some of the Officers who were charged with war crimes.
There are a lot more odd choices in the names of provinces but I think instead of being an ungrateful bugger, I shall thank you for this detailed map Herr Fürstbischof and edit the province_names.csv myself. I really like the way that islands have had big name tags given to them to make clicking on them simpler as their sizes have been reduced to clean up the look of the map. It was such a problem in HOI2's vanilla map to click on some of those Pacific Islands to order troops or aircraft to attack.
