Naganuma Hidenao
Naganuma Hidenao headed the main line of the Naganuma warriors during Japan's Nanboku-chō wars. When the clan could no longer keep its home manor of Naganuma in Shimotsuke Province, he moved the main house to its Nagae manor in Mutsu Province, also called the Minamiyama manor. The move split the clan into the Mutsu Naganuma and Shimotsuke Naganuma branches.
