“The Sakamoto Ryōma Memorial Museum opened in the grounds of the former Urado Castle in Katsurahama, Kōchi, Japan on 15 November 1991. The collection includes correspondence and other documents by Sakamoto Ryōma and his contemporaries and there is also a library of over two thousand books relating to the Meiji Restoration.

“In March 1866, several agents of the shogunate attempted to assassinate Sakamoto Ryōma by ambushing him at the Teradaya ryokan in Kyoto. Two aspects of this have become famous. Firstly, he was alerted just in time by his future wife Narasaki Ryō (Oryō), who was surprised in her bath by the attackers and ran across a garden and up to the second floor of the inn to warn Sakamoto. Secondly, he used a Western firearm, a Smith & Wesson revolver, to fight off these attackers.”
