Sakura Domain
Sadanobu retired from the family headship in 1819, and was succeeded by his son Sadanaga, but continued to influence domain affairs from behind-the-scenes. He successfully petitioned for a change in territory from Shirakawa to Kuwana Domain in Ise Province. Officially, he desired to take over the former territory of the Hisamatsu-Matsudaira family because it had a seaport; however, it was clear that Shirakawa would be unable to withstand the financial deterioration caused by the Edo Bay security measures, and he wished to pass this responsibility on to Hotta Masaatsu of Sakura Domain, whom he disliked.
