Tsuyama Domain (津山藩, Tsuyama han) was a Japanese domain of the Edo period. It was associated with Mimasaka Province in modern-day Okayama Prefecture. In the han system, Tsuyama 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.
