In the han system, Hamada 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 came to an end with its conquest by forces of the Chōshū Domain and its subsequent absorption of Hamada into Chōshū territory.
