 was a Japanese "daimyō" of the mid-Edo period.
The Makino 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.
Makino clan genealogy.
The "fudai" Makino clan originated in 16th century Mikawa Province. Their elevation in status by Toyotomi Hideyoshi dates from 1588. They claim descent from Takechiuchi no Sukune, who was a legendary Statesman and lover of the legendary Empress Jingū.
Sadamichi was part of a cadet branch of the Makino which was created in 1680. These Makino resided successively at Sekiyado Domain in Shimōsa Province in 1683 ; at Yoshida Domain at Mikawa Province in 1705; at Nabeoka Domain in Hyūga Province in 1712; and, from 1747 through 1868 at Kasama Domain (80,000 "koku") in Hitachi Province. 
The head of this clan line was ennobled as a "Viscount" in the Meiji period.
Tokugawa official.
Sadamichi served the Tokugawa shogunate as its nineteenth Kyoto "shoshidai" in the period spanning July 2, 1742, through October 28, 1749. Sadamichi was the father of Makino Sadanaga, who was the twenty-eighth "shoshidai". He would be distantly related to the fifty-fifth "shoshidai", Makino Tadayuki (1824–1878), who was descended from the elder Makino branch.
