The Kanō Domain (加納藩 Kanō-han?)was a Japanese domain of the Edo period. It is associated with Mino Province in modern-day Gifu Prefecture.
In the han system, Kanō 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.
Before the battle of Sekigahara, the central Mino Province was ruled by Oda Hidenobu, Oda Nobunaga's grandson, its base was Gifu (岐阜?). However, as Hidenobu sided with Ishida Mitsunari at the battle of Sekigahara, his territory was confiscated by Tokugawa Ieyasu, and the Gifu Castle was dismantled.
In 1601, Ieyasu granted the area to his son-in-law Okudaira Nobumasa, Gifu was renamed to Kanō (加納?). Okudaira Nobumasa was allowed to build the Kanō Castle with the materials from the dismantled Gifu Castle. This was the birth of the Kanō domain.
