Okabe Domain

Okabe Domain (岡部藩, Okabe-han^?) 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.

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 daimyo. 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.
