Princess Ōyama Sutematsu (大山 捨松, February 24, 1860 – February 18, 1919), born Yamakawa Sakiko (山川 咲子), was a prominent figure in the Meiji era, and the first Japanese woman to receive a college degree. She was born into a traditional samurai household which supported the Tokugawa shogunate during the Boshin War. As a child, she survived the monthlong siege known as the Battle of Aizu in 1868, and lived briefly as a refugee.
