Obama Domain
was the 10th "daimyō" of the Obama Domain. He was the seventh son of Sakai Tadaka of Tsuruga Domain and was posthumously adopted as heir on the death of Sakai Tadatsura in 1806. His wife was a daughter of Okudaira Masashika of the Nakatsu Domain. In 1808, he became "jisha-bugyō" and from 1808 to 1815 served as "Kyoto Shoshidai". In 1815, he was ordered to oversee the reconstruction of the 5-story pagoda at Nikkō Tōshō-gū, which had been destroyed by a fire. Later that year, he was promoted to "rōjū", holding that post until his death in 1828.
