Naosuke, the bakufu Tairō who signed treaties with the Western powers, began to round up sonnō jōi rebels in Kyōto, Edo, and eventually the provinces. Many of Yoshida Shoin's followers were caught up in the dragnet. That year, Yoshida Shōin put down the brush and took up the sword. When Ii Naosuke sent a servant to (unsuccessfully) ask the emperor to support one of his treaties with the foreigners, Yoshida Shōin led a revolt, calling on rōnin to aid him, but received very little support. Nonetheless, he and a small band of students attacked and attempted to kill Ii's servant in Kyoto. The revolt failed, and Yoshida Shoin was again imprisoned in Chōshū. Death In 1859, Chōshū was ordered to send its most dangerous insurgents to Edo's prisons. Once there, Yoshida Shōin confessed the assassination plot, and, from jail, continued to plot the rebellion. He did not expect to be executed until the Tokugawa executed three of his friends. In October 15, he asked for a piece of tissue paper to clear his nasal passage, then recited his final death poem: 'Parental love exceeds one's love for his parents. How will they take the tidings of today?'. Two days later in October 17, he was informed of his death sentence. When it was Yoshida's turn in November 21, he was brought to an open courtyard adjacent to the prison, and led to the scaffold. With perfect composure he kneeled atop a straw mat, beyond which was a rectangular hole dug in the rich, dark earth to absorb the blood. Upon his death by decapitation, his executioner Yamada Asaemon said that he died a noble death. He was 29 years old. After his execution, he was first buried by Itō Hirobumi and his Chōshū comrades near the execution site. In 1863, he was later reburied by his supporters at Wakabayashi, Edo. Posthumous influence At least five of his students, Takasugi Shinsaku, Katsura Kogorō, Inoue Kaoru, Itō Hirobumi and Yamagata Aritomo later became widely known, and virtually all of the survivors of the Sonjuku group became officers in the Meiji Restoration. Takasugi led rifle companies against the shōguns army when it failed to conquer Chōshū in 1864, rapidly leading to the fall of the Tokugawa shogunate. Itō Hirobumi became Japan's first prime minister. Legacy In 1882, Yoshida Shōin was enshrined at Shōin shrine in Wakabayashi, Setagaya-ku (35-1), in Tokyo, and the current
