The publication of Bojutsu Yume Monogatari in 1838 marked a turning point in the life of Takano Chōei, a physician whose career shifted from medical practice to political dissent. By critiquing the Tokugawa shogunate’s handling of the 1837 Morrison Incident, he became a target of authorities, eventually forcing him into a clandestine existence that ended in his death in 1850.
Medical Training and Rangaku
Born in 1804 in Mizusawa, he was originally named Gotō Kyōsai. His transition to medicine began after his adoption by his uncle, Takano Gensai. He moved to Edo in 1820, supported by lottery winnings, to study under Sugita Hakugen and Yoshida Chōshuku. He later refined his expertise at the Narutaki-juku in Nagasaki under the tutelage of Philipp Franz von Siebold, where he translated Dutch texts and collected botanical specimens.

After von Siebold was expelled in 1828, Chōei relocated to Edo. He became a central figure in the Shōshikai, a study group focused on foreign affairs, and reunited with fellow student Watanabe Kazan. During this period, he produced several significant works, including his 1832 Fundamentals of Medicine and later texts regarding famine relief and the management of contagious diseases.
Political Imprisonment and Escape
His criticism of the shogunate in 1838 resulted in his arrest. Sentenced to life in prison, he served five years in the commoners' section of Kodenmachō prison. While incarcerated, he authored Bansha Sōyaku Shōki, documenting the arrival of Western knowledge in Japan. In 1844, he orchestrated his escape by starting a fire in the prison, spending his remaining years using aliases to evade capture.
Final Years in Minami-Aoyama
By March 1850, he returned to Edo, living in Minami-Aoyama. He operated a medical practice under a false identity in an area populated by official residences of the Shōgun's foot soldiers. His hiding place was revealed to authorities in October 1850. During the subsequent arrest attempt, he was killed; official accounts claimed he died by suicide with a dagger, though reports describe a violent confrontation.
