was a Japanese domain of the Edo period. It was associated with Izumo Province in modern-day Shimane Prefecture.
In the han system, Hirose 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 hereditary daimyà Âs were head of the clan and head of the domain.
