Hiroshima Domain
# Hiroshima Domain

The Hiroshima Domain (広島藩, Hiroshima-han) was a domain of the Tokugawa Shogunate of Japan during the Edo period from 1601 to 1871.

The Hiroshima Domain was based at Hiroshima Castle in Aki Province, in the modern city of Hiroshima, located in the Chūgoku region of the island of Honshu. The Hiroshima Domain was ruled for most of its existence by the daimyō of the Asano clan and encompassed Aki Province and parts of Bingo Province with a Kokudaka system value of 426,500 koku. The Hiroshima Domain was dissolved in the abolition of the han system in 1871 by the Meiji government and its territory was absorbed into Hiroshima Prefecture.

## History

In 1589, Hiroshima Castle was commissioned by Mōri Terumoto, head of the powerful Mōri clan and a member of Toyotomi Hideyoshi's Council of Five Elders. In 1591, Terumoto relocated to Hiroshima while it was still under construction, using it as his base to rule his domain covering most of the Chūgoku region. Following the Battle of Sekigahara in 1600, the Mōri were forced out of Hiroshima by Tokugawa Ieyasu and relocated their base to Hagi Castle, losing most of their eastern territories. The Hiroshima han (domain) was subsequently established with Fukushima Masanori as its daimyō (feudal lord), covering Aki Province and parts of neighboring Bingo Province. However, nineteen years later, Hiroshima Castle suffered extensive flood damage and Fukushima repaired it in violation of the Tokugawa shogunate's laws on the construction and repair of castles (see buke shohatto). The shogunate then ordered Fukushima to Kawanakajima Domain, and awarded Hiroshima to the Asano clan, who ruled it for the remainder of the Edo period. Under the Tokugawa Kokudaka system for domains the Hiroshima Domain was assessed at 426,500 koku, the sixth-largest domain in Japan, excepting those held by the Tokugawa-Matsudaira dynasty.

In 1871, the Hiroshima Domain was formally dismantled along with all the other domains in Japan following the Meiji Restoration. The introduction of the Fuhanken sanchisei saw the replacement of the provinces and domains with the prefecture system, and territory of the Hiroshima Domain was organized into Hiroshima Prefecture.
