was a feudal domain under the Tokugawa shogunate of Edo period Japan, in what is now western Ehime Prefecture on the island of Shikoku. It was centered around Uwajima Castle, and was ruled throughout its history by the tozama daimyō Date clan. Uwajima Domain was dissolved in the abolition of the han system in 1871 and is now part of Ehime Prefecture. History Pre-Edo period Uwajima During the Heian period, Uwajima (notably the island of Hiburijima in Uwajima Bay) was a center of piracy in the Seto Inland Sea and became the stronghold of Fujiwara no Sumitomo in his rebellion. During the Muromachi period, a branch of the Saionji family was appointed as governor of the area by the Ashikaga shogunate, but was constantly being invaded his more powerful and aggressive neighbors, including Ouchi Yoshitaka, Mōri Motonari, Ōtomo Sōrin, the Tosa-Ichijo clan and the Chōsokabe clan. The Saionji survived by the fluid loyalties and fierce resistance, but were eventually overcome by Chōsokabe Motochika, who was in turn overthrown by the forces of Toyotomi Hideyoshi. Iyo Province was given to Kobayakawa Takakage, who assigned the area around Uwajima to his adopted son and half-brother, Hidekane. Takakage was later transferred to Kyushu and was replaced by Hideyoshi's general Toda Katsutaka.

He went insane during the campaign, and died in Korea without heir. Hideyoshi then assigned Tōdō Takatora to the domain. A noted castle designer, Takatora spent six years building Itajima Castle, which would later be called Uwajima Castle. Following the Battle of Sekigahara and other campaigns, he was promoted to the 220,000 koku Tsu Domain in Ise Province. Under the Tokugawa shogunate In 1608, Tomita Nobutaka, daimyō of Tsu Domain with 50,000 koku, was ordered to trade places with Tōdō Takatora, and his kokudaka was increased to 101,900 koku. Tomita's wife was the daughter of Ukita Tadaie, and was a famous as a female warrior who had fought against the Mōri army in the Battle of Sekigahara. Her brother Sakazaki Naomori had a conflict with his nephew Ukita Samon. One of his pages had an
