In Japan, a group of assassins called the Four Hitokiri of the Bakumatsu killed a number of people, including Ii Naosuke who was the head of administration for the Tokugawa shogunate, during the Boshin War. Most of the assassinations in Japan were committed with bladed weaponry, a trait that was carried on into modern history. A video-record exists of the assassination of Inejiro Asanuma, using a sword.
