徳川綱吉
In 1681, the second "daimyō" of Iwanuma, Tamura Tatsuaki relocated his seat to Ichinoseki. Tatsuaki was the great-grandson of Date Masamune, and was especially favoured by "shōgun" Tokugawa Tsunayoshi, and despite his "tozama" status enjoyed many of the privileges accorded to a "fudai daimyō".
