Site of Sanuki Castle

Sanuki Domain (佐貫藩 Sanuki-han?) was a Japanese domain of the Edo period, located in Kazusa Province (modern-day Chiba Prefecture), Japan. It was centered on Sanuki Castle in what is now the city of Futtsu, Chiba.

In the han system, Sanuki was a political and economic abstraction based on periodic cadastral surveys and projected agricultural yields.[1] In other words, the domain was defined in terms of kokudaka, not land area.[2] This was different from the feudalism of the West.


The original Sanuki Castle was built by the Satomi clan, rulers of most of the Bōsō Peninsula during the Sengoku period. Following the Battle of Odawara in 1590, the Kantō region by was assigned to Tokugawa Ieyasu by the warlord Toyotomi Hideyoshi, who also restricted the Satomi to Awa Province for their lukewarm support of his campaigns against the Late Hōjō clan. Tokugawa Ieyasu appointed Naito Ienaga, one of his hereditary retainers, to be daimyō of the new 20,000 koku Sanuki Domain.

During the Siege of Fushimi in 1600 prior to the Battle of Sekigahara, Naito Ienaga was one of the last defenders of Fushimi Castle to fall to the forces of Ishida Mitsunari. He was succeeded by his son, Naito Masanaga, who was awarded an additional 10,000 koku for his efforts at the Siege of Osaka. He gained another 10,000 koku for his participation in the suppression of the Satomi clan at Tateyama Domain in Awa Province, and yet another 5,000 koku when Shogun Tokugawa Hidetada visited on an extended falconry expedition, thus bringing his total revenues to 45,000 koku. He was subsequently transferred to Iwakidaira Domain in Mutsu Province.

His replacement, Matsudaira Tadashige, was an 8,000 koku hatamoto of Fukuya Domain in Musashi Province, who was elevated to the ranks of the daimyō with an additional 7,000 koku stipend. He was subsequently transferred to Tanaka Domain in Suruga Province and Samuki Domain reverted to tenryō territory directly under the control of the Tokugawa shogunate.

In January 1639, Sanuki Domain was revived for Matsudaira Katsutaka, a former jisha-bugyō, whose holding had reached 15,000 koku, qualifying him as a daimyō. However, the Matsudaira clan were dispossessed from Sanuki under the tenure of his son, Matsudaira Shigeharu, for mismanagement, and Sanuki Domain again lapsed to tenryō status.

In May 1710, the domain was reestablished as a 16,000 koku holding for Abe Masatane, formerly daimyo of Kariya Domain in Mikawa Province. The Abe clan continued to rule Sanuki until the Meiji Restoration. The final daimyo of Sanuki Domain, Abe Masatsune, initially served with the pro-Tokugawa forces in the Boshin War against the strong advice of his senior retainers and refused to surrender his armory to the new Meiji government. He was subsequently imprisoned for a time, but was pardoned, and was appointed domain governor under the new administration, until the abolition of the han system in July 1871 and subsequently became a viscount under the kazoku peerage. Sanuki Domain became “Sanuki Prefecture”, which merged with the short lived “Kisarazu Prefecture” in November 1871, which later became part of Chiba Prefecture.
