In the han system, Hitachi-Fuchū was a political and economic abstraction based on periodic cadastral surveys and projected agricultural yields. In other words, the domain was defined in terms of kokudaka, not land area. This was different from the feudalism of the West.
The domain was created in 1602, when the Rokugō clan, a prominent family of Dewa Province, was moved to new landholdings given to them for distinguished service in the eastern army during the Sekigahara Campaign. The domain then passed into the hands of the Minagawa family before going to what became the Matsudaira family of Fuchū, a branch of the Tokugawa clan of Mito. Renamed Ishioka-han (石岡藩) in 1869, it was abolished in the Haihan Chiken order of 1871.
