Shudo Junior and Senior High School (修道中学校・修道高等学校) is a university-preparatory school for boys located in Hiroshima City. It is one of the oldest high schools in Japan, with a history of over 290 years. The school was founded within the Hiroshima Castle by the Fifth Lord of Hiroshima Domain (広島藩), Yoshinaga Asano, in 1725. Shudo was originally the Domain School (藩校) teaching sons of samurais in the feudal domain, but was changed to a private school by the Twelfth Lord, Nagakoto Asano, in 1878. The school, students and teachers suffered severely from the atomic bomb dropped on Hiroshima City in 1945.
