Hiroshima Domain

Hiroshima Domain (広島藩, Hiroshima-han) was a han, or feudal domain, of Edo period Japan. Based at Hiroshima castle in the city of Hiroshima, the domain encompassed Aki province and parts of neighboring Bingo province.

Following the battle of Sekigahara in 1600, the han was established with Fukushima Masanori as its daimyō (feudal lord). 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, during which it was the sixth-largest domain in Japan, excepting those held by the Tokugawa-Matsudaira dynasty. The domain was dismantled along with all the others in 1871.
