Koromo Domain (挙母藩, Koromo han) was a feudal domain under the Tokugawa shogunateofEdo period Japan, located in Mikawa Province (modern-day eastern Aichi Prefecture), Japan. It was centered on Koromo Castle in what is now the city of Toyota, Aichi.
A fortification was built near the present site of Koromo Castle during the Kamakura period, and the area was contested in the Sengoku period between the Imagawa clan and the Oda clan. After the establishment of the Tokugawa shogunate, the Miyake clan (formerly of Tahara) were allowed to return to Mikawa and were assigned a 10,000 koku domain on the banks of the Yasaku River. In 1600, Miyake Yasusada built a jin'ya fortified residence approximately a kilometer away from the site of the original fortification, and planted sakura trees all around it. The residence was nicknamed "Sakura-jō " (桜城).
The Miyake moved the seat of their domain to Kameyama DomaininIse Province in 1619, but returned to Koromo from 1636–1674. After 1674, they were finally allowed to return to their ancestral Tahara Domain. Koromo then became tenryō territory ruled directly by the Tokugawa shogunate through appointed daikan administrators to 1688.
In 1688, a branch of the Honda clan was transferred to Koromo from Ishikawa DomaininMutsu Province, remaining to 1749 when it was transferred to Sagara Domain. The Honda were replaced by a branch of the Naitō clan from Annaka DomaininKōzuke Province. The Naitō ruled for the next 120 years until the Meiji restoration, and were allowed to construct the modest castle, Koromo Castle as their headquarters. Two of the Naitō clan daimyō, Masanari and Masahiro, were adopted into the family; they were the elder brothers of Ii Naosuke.
From 1836–1838, the domain suffered from crop failures and famine, which led to a number of large-scale peasant's uprisings. In 1854, the town was largely destroyed by the 1854 Ansei earthquake, and entered into the Bakumatsu period impoverished and with a minor as daimyō. The Ee ja nai ka movement found strong support in the domain. Although the domain dispatched some troops to guard the Tōkaidō and Sunpu Castle during the Boshin War, these troops surrendered to the new Meiji government without resistance.
The domain had a population of 19,253 people in 5078 households per an 1869 census. The domain maintained its primary residence (kamiyashiki) in Edo at Hanzonmon until the An'ei period (1772–1780), when it was relocated to Mita.[1]
After the abolition of the han system in July 1871, the domain became “Koromo Prefecture”, which later became part of Nukata Prefecture, and finally Aichi Prefecture.
As with most domains, Koromo Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.[2][3] At the end of the Edo period, Koromo Domain consisted of 25 villages in Kamo District and 6 villages neighboring Shitara District in Mikawa, and 12 villages in Kumehokujo District, Mimasaka Province, 8 villages in Shūchi District, and Haibara District, both in Tōtōmi Province.
