In 1700, Tadamasa was relocated from Yamagata to Fukuyama, but he ran into difficulties deciding on his territory. After the land survey was completed and the specific territory was decided, Tadamasa finally entered the Fukuyama domain in 1709. However, he was forced to again relocate to Ise Kuwana in 1710 (the seventh year of Hoei). Therefore, his reign lasted only a little more than 10 years.
