Draft:Mashiyama Masatomo

Mashiyama Masatomo (増山正同; March 29, 1843 – April 22, 1887) was a daimyo during the final years of the Edo period, holding the position of the eighth and final lord of the Ise-Nagashima Domain. He belonged to the ninth generation of the Masuyama clan in the Nagashima Domain and was later granted the title of viscount following the Meiji Restoration.

Biography
Born on March 29, 1843, as the second son of Nagai Sanzaemon Nagata, a shogunate retainer with a position of 500 koku, he went by the names Yunosuke, Hayato, and Daigaku. His official rank was Junior Fifth Rank, Bicchu no kami. In 1852, he inherited the leadership of Masuyama Ginnosuke, a branch of the Masuyama clan from the Nagashima Domain, and became a retainer of the 1000 Tawara Kofusho-gumi, which was under the shogunate's control. This led to his incorporation into the Kofusho-gumi. In 1861, he was appointed Goshoin Banshi, and in 1866, he was appointed Goshuban, both of which were significant positions that contributed to the Meiji Restoration. Later, in 1869, he became part of the Yokosuka Magistrate's control, and historical records indicate that he resided at Mizuguchiya Gen'emon in Anzai 4-chome, Shizuoka Prefecture. During the same year, after the legitimate son of Masuyama Masanobu, the seventh lord of the Nagashima Domain, was disinherited, he was adopted by Masanobu. Following Masanobu's passing, he assumed the role of the clan's head. On June 24 of that year, he was appointed as a Chihanji due to the restoration of land ownership. Subsequently, on July 15, 1871, when the feudal domain system was abolished and the prefecture system was established, he was discharged from his position. He later relocated to Tokyo, and in 1876, he became a court priest, eventually rising to the position of chamberlain. In recognition of his contributions, he was granted the title of viscount in 1884, as per the Peerage Ordinance. He died on April 22, 1887, at the age of 45, leaving behind a legacy of service and dedication.

Real father
According to Ito Shigenobu's Nagashima Town History (1974), it has been suggested that Nagai Nagata, the lord of the Yamato-Shinjo Domain, is the biological father of the individual in question. However, upon closer examination, it becomes evident that this claim is inaccurate for several reasons:
 * The death year of Nagai Nagata, the lord of the Shinjo domain, in 1825 does not align with his birth year, Tenpo 14 (1843), creating a discrepancy in the historical records.
 * The name "Sanzaemon" was not a childhood alias or commonly used name for Nagai Nagata, the lord of the Shinjo Domain, indicating a potential error or misunderstanding in historical documentation.
 * According to the Peerage Detailed Tanzaku from the Historiographical Collection of the University of Tokyo, it is noted that Nagai Nagata's grandfather, Naokazu Nagai Oe (Shishichiro), passed away without being in charge of the flag, while his father, Nagai Oe Naokata (Sanzaemon), also passed away. This differs from the information typically associated with the feudal lord, suggesting a need for further investigation or clarification in historical accounts.
