Kokura Domain

Kokura Domain (小倉藩, Kokura-han)', also known as "Kawara-han" (香春藩) or then "Toyotsu-han" (豊津藩), was a Japanese domain of the Edo period. It was associated with Buzen Province in modern-day Fukuoka Prefecture on the island of Kyushu.

In the han system, Kokura 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.
