Ise Sadaoki

Ise Sadaoki (伊勢貞興, 1559 – July 2, 1582) was a samurai, and retainer of the Akechi clan following the Sengoku to Azuchi–Momoyama periods of the 16th century Japan.

Married to Akechi Mitsuhide's daughter, Sadaoki later served under Mitsuhide, then through him, Oda Nobunaga. He died at the age of 23, during the Battle of Yamasaki, in which Mitsuhide was defeated by the forces of Hashiba Hideyoshi. Mitsuhide himself is thought to have been killed by a bandit known as Nakamura about two weeks after the battle.
