was a feudal domain under the Tokugawa shogunate of Edo period Japan. It was located in northern Shinano Province, Honshū. The domain was centered at Iiyama Castle, located in what is now part of the city of Iiyama in Nagano Prefecture."Shinano Province" at JapaneseCastleExplorer.com; retrieved 2013-5-13.
History In 1603, when Matsudaira Tadateru was awarded Kawanakajima Domain, the area around Iiyama was assigned to his retainer, Minagawa Hiroteru as a 40,000 koku holding. This marked the start of Iiyama Domain. however, after Matsudaira Tadateru fell from favour with shōgun Tokugawa Ieyasu and was dispossessed, Minagawa Hiroteru suffered a similar fate and was demoted to the 10,000 koku Hitachi-Fuchū Domain. He was replaced by Hori Naoteru from a cadet branch of the Hori clan of Echigo Province. Hori Naoteru took active steps in flood control and the opening of new rice lands to improve the domain. However, he was transferred to Nagaoka Domain in 1616. Iiyama then went to Sakuma Yasumasa, the son of one of Oda Nobunaga's famed generals, Sakuma Morimasa. The Sakuma clan ruled for three generations until the line died out without an heir in 1638. Iiyama Domain was then assigned to a branch of the Matsudaira clan, formerly from Kakegawa Domain. The Matsudaira ruled for two generations, and returned to Kakegawa in 1706. Iiyama was then assigned to Nagai Naohiro, formerly lord of Akō Domain immediately after the famed Forty-seven rōnin incident. He remained only until 1711 when he was replaced by Toyama Yoshihide, who also stayed for only six years before he too was transferred elsewhere.
In 1717, Iiyama Domain was awarded to a cadet branch of the Honda clan, under whose control it remained until the Meiji Restoration. During the Boshin War, the domain was invaded by pro-Tokugawa forces from Takada Domain, who set fire to the castle town. The domain subsequently supported the imperial armies at the Battle of Hokuetsu and Battle of Aizu. In July 1871, with the abolition of the han system, Iiyama Domain briefly became Iiyama Prefecture, and was merged into the newly created Nagano Prefecture.
Bakumatsu period holdings As with most domains in the han system, Iiyama Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.Mass, Jeffrey P. and William B.
