Asano Nagaakira (March 18, 1586 – October 16, 1632) was a Japanese samurai and daimyō of the early Edo period. He initially ruled Wakayama Domain before being transferred to the Hiroshima Domain, where his family would remain until the Meiji Restoration.
Early Life and Rise to Power
Born Asano Iwamatsu, he was the son of Asano Nagamasa, a senior retainer of Toyotomi Hideyoshi. In 1594, at just eight years old, Nagaakira became a direct retainer of Hideyoshi and was granted a stipend of 3,000 koku. However, after Hideyoshi’s death, he aligned himself with Tokugawa Ieyasu during the pivotal Battle of Sekigahara (1600). For his loyalty, he was awarded the 24,000-koku Ashimori Domain in Mimasaka Province.
In 1613, following the death of his brother Asano Yukinaga, who left no heir, Nagaakira succeeded him as daimyō of Wakayama Domain (Kii Province).
Military Contributions
During the Siege of Osaka (1614–1615), Nagaakira played a key role in Tokugawa Ieyasu’s campaign against the Toyotomi clan. In 1615, when Toyotomi Hideyori’s Western Army launched an attack on Wakayama Castle, Nagaakira led his forces into battle despite being outnumbered, securing victory at the Battle of Kashii.
He also fought in the Battle of Tennōji, the final and decisive confrontation of the siege, where he commanded Tokugawa’s rear guard.
Lord of Hiroshima
In 1619, for his service and unwavering loyalty, Nagaakira was granted the powerful Hiroshima Domain in Aki Province, marking the beginning of the Asano family's rule there, which lasted until the Meiji Restoration.
Nagaakira was married to Furihime, the widow of Gamō Hideyuki and the third daughter of Tokugawa Ieyasu, further solidifying his ties to the Tokugawa shogunate.
His leadership and strategic prowess cemented his family's legacy, making the Asano clan of Hiroshima one of the most influential in Japan’s Edo period.
