Shibata Domain (新発田藩 Shibata-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 Shibata Castle, located in what is nowthe city of Shibata in Niigata Prefecture. It was ruled for all of its history by the Mizoguchi clan.
Mizoguchi Hidekatsu was a general under Oda Nobunaga and subsequently Toyotomi Hideyoshi. He distinguished himself at a number of battles and was rewarded with a 60,000 koku holding in Echigo Province. During the Battle of Sekigahara, he sided with Tokugawa Ieyasu; however as Echigo Province had many supporters and former retainers of the Uesugi clan, he was ordered to remain in Echigo on guard duty. After the establishment of the Tokugawa Shogunate, he was confirmed in his existing holdings, which extended across the Echigo Plain between the Agano River and the Shinano River. This area, which stretched from eastern Niigata City, through Agano, Kamo and Minamikanbara District was excellent rice land, and the actual revenues of the domain were far in excess of its official kokudaka.
