On June 24, 1860, he handed the leadership to his sixth son, Yonekura Masakoto, and retired. He died on May 7, 1863, at age 70. His grave is at Hase-dera temple in Shibuya, Tokyo.
Masanaga had six sons and two daughters with his official wife, a daughter of Manabe Akihiro, daimyō of Sabae Domain. He also had two sons and two daughters with a concubine, the daughter of Itakura Katsunaga, daimyō of Fukushima Domain in Mutsu Province.
