Iwakura Tomomi
The Nagai clan, from Iwatsuki Domain in Musashi Province, ruled from 1756 until the Meiji restoration, with a "kokudaka" reduced to 32,000 "koku". The 4th Nagai "daimyō", Nagai Naosuke, served the Tokugawa shogunate as a "wakadoshiyori", as did the final "daimyō", Nagai Naokoto. During the Boshin War, the domain organized a surrender to Iwakura Tomomi without a fight.
