I've only seen this in one game, but it's also the only game where I've had maps of the area. It's 1620 and I'm Russia. I trade maps with Manchu and discover that Nippon is blessed with two COTs. One is in Kansai and the other in Kanto. Considering they are right next to eachother, this does not seem normal. It should also be noted that Kansai was worth about 475, and Kanto (it only had 3 provinces) was worth 12.
