Sonnō jōi
Prince Arisugawa was a trusted confidant of Emperor Kōmei (1831–1867). During the unsettled period just prior to the Meiji Restoration, when "Sonnō jōi" militants battled troops local to the Tokugawa Bakufu in the vicinity of the Kyoto Imperial Palace in July 1864, (an incident known as the "Kinmon no Hen"), Prince Arisugawa was punished for suspected collusion with Chōshū Domain and sentenced to house arrest.
