Asano Naganori (September 28, 1667 – April 21, 1701) served as the daimyō of the Akō Domain in Japan from 1675 to 1701, holding the title of Takumi no Kami. He is chiefly remembered for his role in the events that inspired the well-known tale of Chūshingura, involving the legendary 47 ronin. This story has become a beloved theme in kabuki performances, jōruri puppet theater, as well as various Japanese literature and films.
Born in Edo as the eldest son of Asano Nagatomo, he hailed from a branch of the Asano clan, with the main lineage based in Hiroshima. His grandfather Naganao was appointed the daimyō of Ako, presiding over a domain with an allocation of 50 thousand koku. Following Naganao's passing in 1671, Nagatomo took up the position, but sadly passed away three years later in 1675. This led to Naganori inheriting his father's role at the tender age of nine.
In 1680, he received the honorary title of Takumi no Kami, which signified his position as the head of carpentry at the imperial court. However, such titles were largely ceremonial during that period and held little substantive authority. As a daimyō governing a relatively small domain, he was periodically assigned minor, temporary positions within the Tokugawa shogunate. In 1683, he was first appointed as one of the two officials responsible for receiving envoys from the imperial court to the Shogunate. This occasion marked his initial encounter with Kira Yoshinaka, the highest-ranking kōke overseeing ceremonial affairs at the Shogunate, who provided guidance on proper etiquette for hosting esteemed guests from Kyoto.
In 1694, he fell gravely ill and, with no biological heir, faced the prospect of his house being dissolved by the shogunate, resulting in the confiscation of his lands and the displacement of his retainers as rōnin. To avert this, he formally adopted his younger brother Asano Nagahiro, also known as Daigaku, who was duly recognized as his successor by the shogunate.
By 1701, he found himself reappointed to the same office. It's documented that his relationship with Kira Yoshinaka had deteriorated, escalating the tension between them. Tragically, on the day of his demise, he unsheathed his sword and endeavored to strike down Kira within the Corridor of the Pines at Edo Castle, located in present-day Tokyo. Although he managed to wound Kira, he ultimately failed to deliver a fatal blow. On that very day, the fifth Tokugawa shōgun Tsunayoshi decreed his sentence of seppuku, which he dutifully carried out.
Upon the shogunate's confiscation of his fief, his loyal retainers found themselves without a lord and thus became rōnin. Under the leadership of Ōishi Kuranosuke, however, they sought retribution for their master's death by assassinating Kira at his residence in Edo on December 15, 1702. These devoted former retainers gained renown as the forty-seven rōnin, their vendetta standing as one of Japan's most celebrated tales of honor and loyalty.

The son of Ouchi Masahiro, he governed from his residence in Yamaguchi in the province of Suo. In 1499, Yoshioki gave refuge to Shogun Ashikaga Yoshitane, who had been driven out of Kyoto by Hosokawa Masamoto. Shogun Yoshizumi, Masamoto’s protégé, ordered the lords of Kyushu to unite their forces against Yoshioki; however, they did not dare to do so, fearing the power of a man who by that time controlled six provinces. Having gathered a substantial army, Yoshioki marched from his native Suo toward Kyoto in order to restore Shogun Yoshitane to power.
