The revenge of the forty-seven Ronin (四十七士 Shi-jū-shichi-shi?, forty-seven samurai) took place in Japan at the start of the 18th century. One noted Japanese scholar described the tale, the best known example of the samurai code of honor, bushidō, as the country’s “national legend.”
The story tells of a group of samurai who were left leaderless (becoming ronin) after their daimyo (feudal lord) Asano Naganori was compelled to commit seppuku (ritual suicide) for assaulting a court official named Kira Yoshinaka, whose title was Kōzuke no suke. The ronin avenged their master’s honor by killing Kira, after waiting and planning for a year. In turn, the ronin were themselves obliged to commit seppuku for committing the crime of murder. This true story was popularized in Japanese culture as emblematic of the loyalty, sacrifice, persistence, and honor that people should preserve in their daily lives. The popularity of the tale grew during the Meiji era of Japanese history, in which Japan underwent rapid modernization, and the legend became entrenched within discourses of national heritage and identity.
Fictionalized accounts of the tale of the Forty-seven Ronin are known as Chūshingura. The story was popularized in numerous plays, including bunraku and kabuki. Because of the censorship laws of the shogunate in the Genroku era, which forbade portrayal of current events, the names were changed. While the version given by the playwrights may have come to be accepted as historical fact by some[who?], the first Chūshingura was written some 50 years after the event, and numerous historical records about the actual events that predate the Chūshingura survive.
The bakufu’s censorship laws had relaxed somewhat 75 years later in the late 18th century, when Japanologist Isaac Titsingh first recorded the story of the Forty-seven Ronin as one of the significant events of the Genroku era. The story continues to be popular in Japan to this day. Each year on December 14, Sengakuji Temple holds a festival commemorating the event.
