酒井氏
Tadatsugu died in Kyoto in the winter of 1596. After Tadatsugu's death, the Sakai clan continued to prosper. In 1604, his descendants moved to Takasaki Domain (50,000 "koku") in Kōzuke Province; in 1616, they relocated to Takata Domain (100,000 "koku") in Echigo Province; in 1619, they were transferred to Matsushiro Domain in Shinano Province; and then, from 1622 through 1868, they were installed at Tsurugaoka Domain (120,000 "koku") in Dewa Province. The head of the Sakai clan was ennobled as a "Count" in the Meiji period.
