Koromo Domain

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.

Two of the Naitō clan daimyō, Masanari and Masahiro, were adopted into the family; they were the elder brothers of Ii Naosuke.

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 domain maintained its primary residence (kamiyashiki) in Edo at Hanzonmon until the An'ei period (1772–1780), when it was relocated to Mita.
