Ashina clan
Aizu Wakamatsu Castle is located in the center of the Aizu basin and at crossroads to Kōriyama to the north and Yonezawa to the east and Murakami on the Sea of Japan coast. During the Nanboku-cho period, the area was ruled by the Ashina clan. Ashina Naomori built within the Aizu basin in 1384. This castle was the predecessor of what later became Aizuwakamatsu Castle. It was ruled by Ashina Moriuji until 1561, when he turned his domain over to his son.
