Ojima Domain (小島藩 Ojima-han), also known as Kojima Domain, was a Japanese domain of the Edo period. It was located in Suruga Province in modern-day what is now part of the ward of Shimizu in the city of Shizuoka, Shizuoka Prefecture.
In May 1689, Matsudaira Nobunari, the adopted son of the castellan of Sunpu Castle, and a wakadoshiyori in the Tokugawa Shogunate was elevated from his former hatamoto status of 4000 koku, to daimyō status of 10,000 koku, and assigned the territory of Ojima, to the east of Sunpu, to be his domain. He was also authorized to start his own branch of the Matsudaira clan, the Takiwaki Matsudaira clan (滝脇松平家). However, due to the small size of his domain, he was not authorized to build a castle, but ruled from a fortified residence, or jin'ya located on the west bank of the Okitsu River.
During the period of the 4th daimyō, Matsudaira Masanobu, the domain faced bankruptcy, which he attempted to resolve with such a large increase in taxes that its peasants rose in a revolt in 1768. Fiscal problems continued over the years, with the 8th daimyō, Matsudaira Nobumoto publishing a tract attempting the explain to both his retainers and his peasants on the need for high taxes and fiscal restraint. The 9th daimyō, Matsudaira Nobuyuki, made all industry within the domain a government monopoly, and sold off permits to raise money.
During the Bakumatsu period, the 11th (and final) daimyō, Matsudaira Nobutoshi, sided with the new Meiji government in the Boshin War of 1867. The domain was abolished with the creation of Shizuoka Domain for the retired ex-Shōgun Tokugawa Yoshinobu, and Nobutoshi was transferred to the newly formed Sakurai Domain in Kazusa province in July 1869.
The site of the former Ojima Jinya is now a local history museum, and the remnants of some foundation walls received government protection as a National Historic Site in 2006.
Holdings at the end of the Edo period
As with most domains in the han system, Ojima Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields. All of the domain's territory was within Suruga Province.
