Sakai Tadakiyo

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

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

Tadakiyo was part of the senior branch of the Sakai.

The fudai Sakai clan originated in 14th century Mikawa province. The Sakai claim descent from Minamoto Arichika. Arichika had two sons: one of them, Yasuchika, took the name Matsudaira; and the other son, Chikauji, took the name Sakai—and this samuari ancestor is the progenitor of this clan's name.

Sakai Hirochika, who was the son of Chikauji, had two sons, and their descendants gave rise to the two main branches of the Sakai clan. Hirochika's younger son, Sakai Masachika, served several Tokugawa clan leaders -- Nobutada, Kiyoyasu and Hirotada; and in 1561, Masachika was made master of Nishio Castle in Mikawa.

Sakai Sigetada, who was the sun of Masachika, received the fief of Kawagoe Domain in Musashi province in 1590; and then in 1601, Sigetada was transferred to Umayabashi Domain in Kōzuke province.
