Hamamatsu Domain
In 1845, with the resignation of head "Rōjū" Mizuno Tadakuni over the failure of the Tenpō Reforms and subsequent exile from Hamamatsu Domain to Yamagata Domain in Dewa Province, Inoue Masaharu was able to achieve the Inoue clan's goal of returning to Hamamatsu after an absence of 28 years.
