Hiroshima Domain

The Hiroshima Domain (広島藩, Hiroshima-han) was a large domain that owned all of Aki Province and half of Bingo Province. It occupies most of current Hiroshima Prefecture. The domain office was located at Hiroshima Castle in Sato District, Aki Province (renamed Numata District in 1664), Hiroshima (present-day Motomachi, Naka Ward, Hiroshima City, Hiroshima Prefecture). It is often called Geishu Domain (or Aki Domain). 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.
