Tokugawa Ieshige
In 1767, Sagara Domain was awarded to Tanuma Okitsugu, who rose from very humble status as a page to Shōgun Tokugawa Ieshige, to chamberlain, and then grand-chamberlain and "rōjū" under Shōgun Tokugawa Ieharu. He was also elevated to the status of "daimyō" when he was awarded Sagara Domain, and over the years increased its revenues from 10,000 "koku" to 57,000 "koku". Sagara prospered greatly under his economic reforms, and a road was built linking it to the great Tōkaidō highway connecting Edo with Kyoto. However, after Tokugawa Ieharu’s death Tanuma Okitsugu soon fell from favor, and reduced in rank and income. His grandson, Tanuma Okiaki, inherited a domain reduced back to its former 10,000 "koku" status in 1787, and less than a year later, was transferred to Shimomura Domain in Mutsu Province. Sagara Domain became a "tenryō" territory ruled directly by the "Shōgun".
