Takasu Domain
The was a Japanese domain located in Mino Province (present-day Kaizu, Gifu). For most of its history, it was ruled by the Takasu-Matsudaira, a branch of the Tokugawa clan of Owari Domain. Matsudaira Katamori, Matsudaira Sadaaki, Tokugawa Yoshikatsu, and Tokugawa Mochinaga, four important figures in Bakumatsu-era Japan, were the sons of Matsudaira Yoshitatsu, one of Takasu's last "daimyō". History. In 1600, after the Battle of Sekigahara, Takagi Morikane was dispossessed of Takasu Castle for having sided with the pro-Toyotomi Western Army under Ishida Mitsunari. He was replaced by Tokunaga Nagamasa, one of Tokugawa  Ieyasu’s generals and was assigned a fief with a "kokudaka" of 50,673 "koku". The marked the start of Takasu Domain under the Tokugawa shogunate. His son, Tokunaga Masashige, increased the "kokudaka" to 53,000 "koku"; however, he was dispossessed in 1628 over his failure to complete the rebuilding of the walls of Osaka Castle, and the domain was suppressed. Takasu Domain was revived in 1640 as a 22,000 "koku" holding for a cadet branch of the Ogasawara clan from Sekiyado Domain in Shimōsa. However, the domain suffered greatly from flood damage, and the shogunate transferred the Ogasawara to Katsuyama Domain  in Echizen in 1691. The domain was revived a third time in 1700, this time as a 30,000 "koku" holding for Matsudaira Yoshiyuki, the younger son of Tokugawa Mitsutomo of Owari Domain. Matsudaira Yoshiyuki was already "daimyō" of the 30,000 "koku" Takai Domain in Mino Province since 1681, and traded this territory of Takasu Domain, which then became a subsidiary to Owari Domain. The domain remained in the hands of his descendants until the Meiji restoration. Although administered as a part of Owari Domain, the position of Takasu Domain was somewhat ambiguous, as it was authorized directly by the shogunate  rather than by Owari Domain. On the other hand, its "daimyō" lived permanently in Edo, and administered domain affairs through appointed officials, rather than residing in the domain and was thus not subject to "Sankin-kōtai". Bakumatsu period holdings. As with most domains in the han system, Takasu Domain consisted of a discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
