Nagaoka Domain

Nagaoka Domain (長岡藩, Nagaoka-han^?) was a fudai feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in Echigo Province, Honshū. The domain was centered at Nagaoka Castle), located in what is now part of the city of Nagaoka in Niigata Prefecture. It was often referred to as Echigo-Nagaoka Domain (越後長岡藩, Echigo-Nagaoka-han^?) to disambiguate itself from the smaller Yamashiro-Nagaoka Domain (山城長岡藩, Yamashiro-Nagaoka-han^?) in what is now Nagaokakyo, Kyoto. The domain was ruled by the Makino clan for most of its history. It was also the center of some of the fiercest fighting of the Boshin War, during the summer of 1868. Admiral Yamamoto Isoroku was the son of a Nagaoka samurai.
