Asano Nagaakira served as a daimyō and lord of the Bitchū-Ashimori han in the early Edo period.  Nagaakira was the second lineal head of the Kii-Wakayama han, succeeding his older brother, Asano Yoshinaga.  He was also the first lineal head of the Aki-Hiroshima han and second lineal head of the primary Asano clan.

Nagaakira was born in Sakamoto in the Shiga District of Ōmi Province as the second son of Asano Nagamasa.

In 1594, Nagaakira was awarded a fief of 3,000 koku while serving under Toyotomi Hideyoshi.

In 1600, Nagaakira began to serve Tokugawa Ieyasu after the Battle of Sekigahara, and acted as a servant of Tokugawa Hidetada.  In 1610, he was awarded a fief of 24,000 koku in Ashimori in Bitchū Province.

In 1613, his older brother, Yoshinaga, died of illness with no lineal heir.  Asano Ujishige endorsed Asano Nagashige, the third younger brother of Yoshinaga who had friendly relations with the Tokugawa family, to become Yoshinaga’s successor.  Owing, however, to Yoshinaga’s will in addition to the mediation of Nagamasa’s formal wife, Chōsei-in, Nagaakira (the second younger brother of Yoshinaga), backed by Asano Tadayoshi, became the next lord of the Kishū domain. 

In 1614, Nagaakira participated in the Battle of Kizugawaguchi in the opening stages of the Winter Campaign of the Siege of Ōsaka.  In 1615, during the Summer Campaign, Nagaakira’s forces killed Ban Naoyuki, Tannowa Shigemasa, and others at the Battle of Kashii.  In Kii Province, however, Nagaakira was confronted with uprisings including the Kitayama ikki and the Kishū ikki by local bushi and mercenaries.  This caused Nagaakira to quickly return to his home province in an effort to quell the uprisings.

In 1619, the Edo bakufu removed Fukushima Masanori from his position and transferred Nagaakira to Hiroshima in Aki with a fief of 420,000 koku.  Asano Ujishige was assigned to receive Hiroshima Castle and sought to become a chamberlain, similar to when he owned territory in Kai.  On 11/26, however, at Mihara in the Mitsugi District of Bingo Province, Nagaakira assassinated Ujishige owing to Nagaakira’s opposition to a tertiary allocation of 30,000 koku to him.  Ujishige’s son, Tomoyoshi, also committed seppuku.

While the Edo bakufu viewed this incident was viewed as a problem, Nagaakira’s designated heir, Gamō Tadasato, the lord of the Aizu domain, along with his father-in-law, Tōdō Takatora, advocated for Nagaakira so the bakufu did not impose any punishment.

Nagaakira died in Hiroshima in 1632 and was succeeded by his second son, Asano Mitsuakira.
