Toyooka Domain

Sugihara had fought on the Western (losing) side, but he was married to a daughter of Asano Nagamasa, so he escaped any punishment, but was instead rewarded with a 20,000 koku holding.

A nephew, Sugihara Shigeharu was posthumously adopted, and the Tokugawa shogunate decided to accept this arrangement, albeit by reducing the domain to 10,000 koku.

This created severe financial hardship, and the domain was forced to fire many of its retainers and to reduce the stipends of its remaining samurai.

The 7thdaimyō, Kyōgoku Takaari constructed a trading hall to regulate commerce of many products which had been proclaimed domain monopolies.

During the Bakumatsu period, the 9th daimyō, Kyōgoku Takamatsu was ordered by the shogunate to construct an artillery battery for coastal defense in 1862.
