Japanese feudal domain located in Tanba Province
 was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Tanba Province in what is now the central portion of modern-day Kyoto Prefecture. It was centered around Sonobe "jin'ya", which was located in the Sonobe neighborhood of what is now the city of Nantan, Kyoto.
History.
In 1619, Koide Yoshichika, the 3rd "daimyō" of Izushi Domain returned the domain to his elder brother (who had been "daimyō" of Kishiwada Domain, and was given the newly created fief of Sonobe, with a "kokudaka" of 29,800 "koku". He built Sonobe jin'ya, the castle town and completed various irrigation and land improvement works. On his retirement, he took 5000 "koku" of the domain, reducing its "kokudaka" to 25,000 "koku" (as 500 koku had been added through the opening of new rice fields). On his death, this 5000 "koku" portion was divided between the two younger brothers of the 2nd "daimyō", Koide Fusatomo. The 4th "daimyō", Koide Fusasada, served as "Jisha-bugyō" and "wakadoshiyori" in the shogunal administration, notwithstanding his clan's status as a "tozama daimyō". He also reduced the domain to 24,000 "koku" by ranting 1000 "koku" to his younger brother. The 5th "daimyō", Koide Fusayoshi, also served as "jisha-bugyō" and "wakadoshiyori". However, during the tenure of the 7th "daimyō", Koide Fusatake, the domain suffered from repeated natural disaster, including flooding, crop failure and famine, which ruined the clan's financial resources. The increase in price and taxes led to a widespread revolt in 1787, which was worsened by a fire which destroyed most of the town. The domain implemented a monopoly system on tobacco and lumber, which helped alleviate its financial problems. During the Bakumatsu period, under its final "daimyō", Koide Fusanao, the domain was one of the first to side with the imperial cause. As such, it was selected by the Meiji government to be a place of refuge for Emperor Meiji in the event that Kyoto be attacked during the Boshin War, and the domain was authorized to reconstruct its jin'ya into a Japanese castle, the last to be built. Following the Meiji restoration he was made viscount ("shishaku") in the "kazoku" peerage. In 1871, with the abolition of the han system, Sonobe Domain became "Sonobe Prefecture". and subsequently became part of Kyoto Prefecture.
Holdings at the end of the Edo period.
Most domains in the han system, which consisted of several discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
