In 1701, Asano Naganori, a daimyo of the Akō Domain, attacks Kira Yoshinaka in Edo Castle and is ordered to commit seppuku, leading to his samurai becoming ronin (masterless samurai).
In December 1702, the forty-seven ronin, led by Oishi Yoshio, execute a carefully planned attack on Kira Yoshinaka's mansion to avenge their master's death, an event celebrated in Japanese culture as a symbol of loyalty and honor.
The Hollywood movie '47 Ronin,' directed by Carl Rinsch and starring Keanu Reeves, is released, presenting a fantasy-based interpretation inspired by the historical event.
