Kitsuki Domain (杵築藩, Kitsuki-han) was a Japanese domain of the Edo period. It is associated with Bungo Province in modern-day Ōita Prefecture on the island of Kyūshū. In the han system, Kitsuki 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.
