Okabe Domain

 was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Musashi Province (modern-day Saitama Prefecture), Japan. It was centered on Okabe "jin'ya" in what is now part of the city of Fukaya, Saitama.
History.
The Abe clan were retainers of the Imagawa clan, and later went into the service of Tokugawa Ieyasu. Abe Nobumori was a 5250 "koku" "hatamoto" who served under Honda Masanobu at the Battle of Sekigahara. He subsequently served under Tokugawa Hidetada at the Siege of Osaka, but was not given an increase in revenues until he was awarded 4000 "koku" in 1636. In 1649, he was appointed commander of Osaka Castle, which came with a 10,000 "koku" stipend, which gave him enough for the title of "daimyō". However, his 19,250 "koku" consisted of widely scattered holdings in Musashi, Settsu, Mikawa and Shimotsuke provinces.
His son, Abe Nobuyuki, gave 1000 "koku" to each of his two brothers in 1662; however, on his appointment as Deputy Commander of Osaka Castle in 1677, he received an increase of 3000 "koku", bringing the domain to 20,250 "koku". Nobuyuki’s son Abe Nobutomo received a further increase of 2000 "koku" in 1682. However, his son Abe Nobumine turned 2000 "koku" over to a younger brother in 1701. Nobumine also moved the seat of the domain to Okabe in Musashi Province.
Likewise, the 5th daimyo, Abe Nobukata, gave 1000 "koku" to his younger brother in 1706.
The 13th and final "daimyō", Abe Nobuoki, participated in the suppression of the Mito Rebellion, but otherwise played little part in the Boshin War and pledged himself to the Meiji government in 1868. His holdings in Musashi were forfeited to the government, and he moved the seat of his domain to Hanhara in Mikawa Province (now part of Shinshiro, Aichi), where he continued to rule over the remainder of his domain until the abolition of the han system in 1871.
Holdings at the end of the Edo period.
As with most domains in the han system, Okabe Domain consisted of several discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
