Tokugawa Iesato
Excluding the Tokugawas, the initial "kazoku" rank distribution for the former "daimyō" lords depended on rice revenue: those with 150,000 "koku" or more became marquesses, those with 50,000 "koku" or more become counts, and those with holdings rated below 50,000 "koku" became viscounts. The head of the Tokugawa clan, Tokugawa Iesato, became a prince, the heads of primary Tokugawa branch houses ("shinpan daimyō") became marquesses, the heads of the secondary branches became counts and the heads of more distant branches became viscounts. The head of the Matsudaira (Fukui Domain) branch was raised to the rank of marquess from the rank of count in 1888. In 1902, the former "shōgun" Tokugawa Yoshinobu was created a prince, and the head of the Mito "Shinpan" house was raised to the same rank, prince, in 1929.
