Shō Nei
Rizan oversaw the defense of Mie Castle in Naha harbor and successfully repelled an initial Japanese landing there. After the fall of Shuri Castle, the royal palace, and the surrender of King Shō Nei, Rizan was taken captive along with the king and a number of other officials. They were brought to Kagoshima, the capital of Satsuma Domain, and then to Sunpu, where they met with the retired former shōgun Tokugawa Ieyasu, and were forced to sign a number of vows of fealty and allegiance to the Shimazu clan lords of Satsuma. Refusing to do this, Rizan was decapitated.
