Shibata Domain (新発田藩,Shibata-han) was atozamafeudal domain under theTokugawa shogunate ofEdo periodJapan. It is located inEchigo Province,Honshū. The domain was centered atShibata Castle, located in what is now the city ofShibata inNiigata Prefecture.[1] It was ruled for all of its history by theMizoguchi clan.[2]
Mizoguchi Hidekatsu was a general underOda Nobunaga and subsequentlyToyotomi Hideyoshi. He distinguished himself at a number of battles and was rewarded with a 60,000koku holding in Echigo Province. During theBattle of Sekigahara, he sided withTokugawa Ieyasu; however as Echigo Province had many supporters and former retainers of theUesugi clan, he was ordered to remain in Echigo on guard duty. After the establishment of theTokugawa Shogunate, he was confirmed in his existing holdings, which extended across the Echigo Plain between theAgano River and theShinano River. This area, which stretched from easternNiigata City, throughAgano,Kamo andMinamikanbara District was excellent rice land, and the actual revenues of the domain were far in excess of its officialkokudaka.
The seconddaimyō of Shibata,Mizoguchi Nobukatsu, split a 12,000koku holding off of the domain for his younger brother, creating Sōmei Domain (沢海藩,Sōmei han), which lasted to 1687. Thekokudaka of the domain was reduced from 60,000 to 50,000 with the remaining 2,000 coming from new rice lands developed within the domain. Nobukatsu was very active in developing new lands, and an additional 15,500koku were splint amongst his three younger sons on his death, leaving the main 50,000koku holding intact for his heir. The 8thdaimyō,Mizoguchi Naoyasu established aHan school and invited noted gardeners fromEdo andKyoto as part of his rebuilding of thecastle town. The 10thdaimyō,Mizoguchi Naoaki, successfully petitioned the shogunate for an increase inkokudaka from 50,000 to 100,000koku, although there was considerable debate within the domain as to whether or not the increased taxation was worth the increase in prestige and status.
During theBoshin War, the 12thdaimyō,Mizoguchi Naomasa joined theŌuetsu Reppan Dōmei; however, there was extensive opposition within the domain, and he was forced to quickly switch sides to the imperial cause.
In July 1871, with theabolition of the han system, Shibata Domain briefly became Shibata Prefecture, and was merged into the newly createdNiigata Prefecture. Under the newMeiji government, Mizoguchi Naomasa was given thekazoku peerage title ofhakushaku (count),[3] and later served as a member of theHouse of Peers
As with most domains in thehan system, Shibata Domain consisted of several discontinuous territories calculated to provide the assignedkokudaka, based on periodiccadastral surveys and projected agricultural yields.[4][5]
