The domain was centered on Iino Jin’ya, a fortified residence in what is now the city of Futtsu, Chiba.
The 10th (and final) daimyō of Iino Domain, Hoshina Masaari, served as wakadoshiyori, and played an important role as a commander in the Second Chōshū expedition.
However, during the Boshin War, he switched sides to the Satchō Alliance and was later appointed to judge the guilt of those who had opposed the Meiji Restoration, including many of his relatives from the Hoshina clan of Aizu.
[1] As with most domains in the han system, Iino Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.
[2][3] In the case of Iino Domain, the exclave it controlled in Settsu Province was far larger than its home territory in Kazusa, and the domain maintained a secondary Jin’ya in that province.
