The Hamada Domain (浜田藩 Hamada-han) was a Japanese domain of the Edo period. It was associated with Iwami Province in modern-day Shimane Prefecture. 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.
