Yokosuka Domain

[1] In February 1601, Ōsuga Tadamasa, lord of Kururi Domain in Kazusa Province, was allowed by Tokugawa Ieyasu to return to his ancestral estates in Tōtōmi, and was granted the status of a 55,000 koku daimyō.

His son, Matsudaira Shigetada, former castellan of Sumpu Castle became daimyō in 1621, and had his revenues increased to 40,000 koku before being transferred to Kaminoyama Domain in Dewa Province the following year.

Honda proved to be a very unpopular ruler, spending prolifically on prostitutes and sake, ignoring matters of governance, imprisoning or executing his advisors and establishing a network of spies and informers throughout the domain.

After severely increasing taxes and issuing a series of 100 repressive ordinances in 1682, the domain was struck by a typhoon, after which the population rose in revolt.

[3] During the Bakumatsu period, the eighth (and final) daimyō, Nishio Tadaatsu, initially attempted to remain neutral, but later contributed his forces to the imperial armies.
