Hamamatsu Domain (2/2)Ruled by twelve famous families

He was Tadatoshi Aoyama, a senior vassal of Tokugawa Ieyasu.
For the first time in the Aoyama family, there are three generations of Hamamatsu feudal lords from the same family.
However, Tadatoshi Aoyama, the second generation of the Aoyama family, passed away at the age of 35, and his younger brother Tadashige Aoyama did not make any significant achievements as a feudal lord, and was transferred from the Hamamatsu domain to the Kameyama domain.

Afterwards, the Matsudaira family assumed the position of lord of the Hamamatsu domain, and there were two types: the Matsudaira (Honjo) family and the Matsudaira (Okochi/Nagasawa) family.
There were six feudal lords from the two Matsudaira families, but the last Matsudaira feudal lord, Motomasa Matsudaira, held an important position in the shogunate and had almost no involvement in the domain's politics.
Motomasa Matsudaira passed away at the young age of 19.

After that, the Inoue family became the feudal lord.
Masatsune Inoue, the first lord of the Inoue family, held various positions in the shogunate, including temple magistrate, Kyoto shoshidai, and roju.
His successor, Masasada Inoue, died young at the age of 33, and Masatoshi Inoue, who then assumed the position of lord of the domain, was replaced by Tadakuni Mizuno, the leader of the Tenpo reforms, due to the women's issue.

The Mizuno family produced the second lord of the Hamamatsu domain, Tadakuni Mizuno and his son Tadashi Mizuno, but both held positions in the shogunate such as roju, so they were not involved in the reign of Hamamatsu.
Incidentally, Tadashi Mizuno is said to have promoted the construction of the Yokosuka Shipyard.

After the Mizuno family served as the second lord, the reins of lordship returned to the Inoue family.
Masaharu Inoue, the eldest son of Masahiro Inoue, became the lord of the domain after Tadayoshi Mizuno.
He also held important positions in the shogunate, such as performer, temple and shrine magistrate, and Osaka castle lord, before returning to become the lord of Hamamatsu Castle.

In fact, there is an anecdote that the Mizuno family tried to move to Yamagata, where they were transferred, while still in debt to the people, and the Inoue family intervened and placated the people and ended the uprising.

Masaharu Inoue was also a capable feudal lord, and in addition to encouraging the production of Hamamatsu textiles using cotton yarn, he also established the domain school Katsumeikan and devoted himself to the education of feudal retainers.

The last lord of the domain, Masanao Inoue, served as roju (roju) before going to Kyoto to join the 14th shogun, Iemochi Tokugawa, in the second Choshu expedition in 1866.
After the Meiji Restoration, he lived a modest life and died in 1901.

Hamamatsu clan summary

Many of the lords of the Hamamatsu domain held positions in the shogunate, such as roju, Kyoto shoshidai, temple and shrine magistrate, and rose through the ranks, but they did not leave much of a mark as lords of the Hamamatsu domain.
As a result, while there were no major problems in the Hamamatsu clan, it reached the end of the Edo period without developing any outstanding people.
Furthermore, there is a strong opinion that Tadakuni Mizuno became the lord of the domain in order to give him a foil.
