|Lord of Hiroshima|
|Born||August 28, 1842|

Asano Nagakoto ( , August 28, 1842 - February 1, 1937) was a daimy? of Hiroshima Domain for a short time after the Meiji Restoration. For the rest of the Meiji period, he was a politician and diplomat, and was one of the last surviving Japanese daimy? (Hayashi Tadataka and Wakebe Mitsunori outlived him).
Adopted by Asano Nagamichi, he served as assistant to his adoptive father through the 1860s, and attended many of the meetings and events surrounding the restoration of Imperial rule, and as such was one of many who advised the sh?gun Tokugawa Yoshinobu to return power to the Emperor of Japan. Unlike many from domains such as Satsuma and Ch?sh?, however, Asano was opposed to taking military action against the shogunate. His childhood name was Kiyotsuchi () later Tamegoro ().
Nagakoto became the twelfth daimy? of Hiroshima in 1869 upon Nagamichi's retirement. The domains (han) were abolished in 1871, but Asano was granted the title of Marquis (k?shaku) under the kazoku system of peerage which was instituted at that time.
He became a member of the Genr?in (Chamber of Elders) in 1880, was appointed ambassador to Italy two years later, and served in the House of Peers for a time as well. Though living and serving in Tokyo, he worked to support industry and other enterprises in his home area, newly dubbed Hiroshima Prefecture.
The Asano Library (now the Hiroshima Central City Library) opened in 1926, and Asano died in 1937 at the age of 96.
