Sakai Tadakiyo

Sakai Tadakiyo (酒井 忠清, November 29, 1624 – July 4, 1681), also known as Uta-no-kami,[1] was a daimyō (feudal lord) in Kōzuke Province, and a high-ranking government advisor and official in the Tokugawa shogunate of Japan.[2]

The Sakai were identified as one of the fudai or insider daimyō clans which were hereditary vassals or allies of the Tokugawa clan,[3] in contrast with the tozama or outsider clans.
