Chushingura is one of the most popular Samurai story since Edo period. The story is based on "the murder case of Ako in Genroku era." In April 21, 1701, Asano Takuminokami Naganori, the lord of Ako land, attempted murder Kira Kozukenosuke Yoshihisa in Edo castle where drawing sword was seriously restricted (charge of death for the violation). Asano was ordered Seppuku right next day and his land was abandoned. At the night of December 14, 1702, Oishi Kuranosuke Yoshio and other 46 ronin, Samurai of Asano, broke into Kira's house and killed Kira for finishing the murder that their lord could not accomplish. They brought the head of Kira to the grave of Asano in Sengakuji, and most of them did Seppuku after the revenge.
Because they were allowed to do honorable Seppuku, their act of the revenge as considered as the justice according to Bushido, and the case became the popular story of royal Samurai.
