Sakamoto Ryoma: The Runaway Samurai Who Wrote of Giving Japan a Good Wash, and the Hero a Novel Made Bigger
Born the second son of a low-ranking Tosa samurai family, he deserted his domain at 26 (28 by the traditional count), became Katsu Kaishu's disciple, set up the Kameyama Shachu trading company in Nagasaki, helped bring Satsuma and Choshu into alliance, and was assassinated in Kyoto on his birthday by the old calendar, aged 33 by the traditional count. His letters to his sister Otome are now Important Cultural Properties. A late-Meiji magazine reader poll of heroes from around the world reportedly put him only 58th; he became a household hero after Shiba Ryotaro's 1962 novel. This covers his life, which stories hold up, and what to see in Kochi, Nagasaki, and Kyoto.
