Yoita Domain

Ii Naonori (井伊直矩, February 1, 1694 – April 23, 1742) was the 3rd Ii daimyō of Kakegawa Domain, and the 1st Ii daimyō of Yoita. Masazumi was the fourth son of Ii Naooki of Hikone Domain, and the adopted heir of Ii Naotomo. He became daimyō in 1705 when his adopted father was relived of his position by the Tokugawa shogunate due to metal illness and his refusal to go on the sankin kōtai to Edo. The domain was punished by a reduction in kokudaka from 35,000 to 20,000 koku. The following year, Naonori was transferred from Kakegawa to Yoita in Echigo Province, which had an equal kokudaka, but did not have the prestige of a castle. In 1715, he was ordered to serve as bugyō presiding over the 100th anniversary of Tokugawa Ieyasu's death at the Nikkō Tōshō-gū. In retired in 1731, and died at the domain's Edo residence in 1742.
