Tsurumaki Domain

Tsurumaki Domain (鶴牧藩, Tsurumaki-han^?) was a feudal domain under the Tokugawa shogunate of the Edo period, located in, Kazusa Province (modern-day Chiba Prefecture), Japan. It was centered on Tsurumaki jin'ya in what is now the city of Ichihara, Chiba. It was ruled for the entirety of its history by a branch of the Mizuno clan. The name of “Tsurumaki” came from the Mizuno kamiyashiki in Edo, which was located in Wadeda-Tsurumaki-cho.

Tsurumaki Domain was created on May 19, 1827, when Mizuno Tadateru, the daimyō of Hōjō Domain in Awa Province relocated his jin'ya from Awa to Kazusa. As he was entitled by his status to have a castle, rather than a fortified residence, his jin’ya was called "Tsurumaki Castle". He died the following year, and his adopted son, Mizuno Tadamitsu, also served as a wakadoshiyori in the Shogun’s court in Edo. Tadamitsu’s son Mizuno Tadayori fought on the Shogunal side in the Boshin War of the Meiji Restoration, attacking his pro-imperial neighbors. As a result, he was forced to give up most of his holdings scattered around Awa and Kazusa provinces in exchange for new lands in 1869. However, he was pardoned by the new Meiji government the following year, becoming domainal governor until the abolition of the han system in 1871. He was subsequently made a viscount (shishaku) in the kazoku peerage, and the former Tsumaki Domain absorbed into the short-lived Kisarazu Prefecture before becoming part of modern Chiba Prefecture.
