evidence: One area of the map that I always found messy is the current layout of provinces and territorial ownership in Ezo (modern day Hokkaido) and the surrounding Sakhalin (Karafuto/Kita Ezo) and Kuril (Chishima) islands. Although these islands became mostly important at the tail end of EU4's timeline, this region was the scene of an unusual and intense race between Russia and Tokugawa Japan, to expand their influence in the region at the expense of the native Ainu people. These suggested changes are to help EU4 better represent historical events that occurred on Hokkaido, Sakhalin and Kuril islands. Several important points in the region's history are impossible to recreate currently given how the map is laid out and I would like to address that, along with other historical inaccuracies that I think can be solved. I will make several posts detailing some ideas I would like to share and get some feedback on this subject!
