Origins & Early Life

Ōishi Yoshio (大石 良雄; 24 April 1659 – 20 March 1703) was the chamberlain (karō) of the Akō Domain in Harima Province (now Hyōgo Prefecture), Japan (1679 - 1701). He is known as the leader of the Forty-seven Rōnin in their 1703 vendetta and thus the hero of the Chūshingura. He is often referred to by his pseudonym, Ōishi Kuranosuke (大石内蔵助; Japanese pronunciation: [oꜜː.i.ɕi̥ kɯ.ɾa.no.sɯ̥.ke]). He served daimyō Asano Naganori as the head chamberlain (hittōgarō (筆頭家老)) for the Akō estate, supervising the daily running of the castle and the samurai. Due to the Tokugawa rules which required all the daimyō to spend every other year in Edo (now called Tokyo) the chamberlain was a very important man and the de facto ruler of the estate when the daimyō was away from his home province.

Career & Major Achievements

Having attained this office at a rather young age, he is said to have had the implicit trust of his lord. When Asano committed seppuku as punishment for his failed attempt to kill Kira Yoshinaka in Edo castle and the Tokugawa shogunate abolished the house of Asano of Akō, Ōishi was in Akō and managed all its administrative issues. He persuaded other samurai to peacefully yield control of the castle to the agents of the Shogunate. During the next two years many people wondered what Ōishi would do as he had a reputation as an honourable and capable man. He attempted to get the permission to re-establish the house of Asano of Akō but failed.

Enduring Legacy & Impact

He then began a careful plot to kill Lord Kira, but to throw off suspicion, first spent time (and money) in the geisha houses of Kyoto. This type of ruse is referred to as hiru andon (昼行灯, daylight lantern) – appearing to be serving no useful purposes, and this term is frequently applied to Ōishi. He carried out his role well – and secretly coordinated the movements of the remaining loyal Asano samurai. Nearly two years passed before the attack was launched. In January 1703 (by the old Japanese calendar, the 12th month, 14th day) he, with 46 other Akō rōnin, attacked Kira at his residence in the Honjo neighborhood of Edo.
