The Obama Domain小浜藩, was a Fudai feudal domain of a Edo period of Japan. it is located in Wakasa Province, in the Hokuriku region of the island Honshū. The domain was centered at Obama Castle, located in the center of what is now the city of Obama in Fukui Prefecture.
Unlike nearly fudai domains in the han system that consisted of discontinuous territories calculated to give the assigned kokudaka, based on periodic cadastral surveys & projected agricultural yields, Obama Domain controlled any of the province of Wakasa, as well as some scattered small holdings in neighbouring Echizen and Omi.
