Ogasawara Ienaga

Ogasawara Ienaga was a Kamakura warrior and the second head of the Iwami Ogasawara, son of the line's founder Nagachika. When his father died in 1313, he inherited the Kawamoto and Mura estates in Ōchi district, Iwami Province, and moved there from Awa with his heir Nagatane.

Father and son developed the two estates for about twenty years. Tradition holds that Ienaga died in battle in the wars that brought down the Kamakura shogunate in 1333, and he was succeeded by Nagatane.
