Narasaki Ryō (楢崎 龍, July 23, 1841 – January 15, 1906) was a Japanese woman and the wife of Sakamoto Ryōma, an architect of the Meiji Restoration.

[1] She worked at Kyoto's Teradaya Inn, and while taking a bath in the evening on March 9, 1866, heard one of the assassins outside, who immediately thrust his spear through the bathroom window right by her shoulder.

She then quickly jumped out of the bathtub and, putting on her robe without a sash, ran out into a garden and went up to the second floor of the inn to warn Sakamoto, who was in his room with his bodyguard Miyoshi Shinzo.

Sakamoto's injuries during the attack led them to visit several hot springs in Kagoshima Prefecture that were believed to have healing properties, in what has been said to be the first Japanese honeymoon.

Eight years later, with assistance from Mitsuaki Tanaka and Kagawa Keizō, and her younger sister Nakazawa Mitsue, her widower Nishimura Matsubē and his colleagues managed to erect a tombstone for her in August 1914.
