Makimura Ushinosuke served as a bushō during the Azuchi-Momoyama and early Edo periods.　　

In 1593, Ushinosuke was born as the son of Makimura Toshisada.  His childhood name was Hyōmaru.  On 7/10 of the same year that Ushinosuke was born, Toshisada died of illness while on deployed as a magistrate for warships in the Bunroku Expedition on the Korean Peninsula.  Owing to the fact that Ushinosuke was an infant at the time, his uncle, Inaba Michitō (Toshisada’s younger brother) inherited the family.  However, this was to serve on behalf of Ushinosuke until he reached the age of maturity.

In 1607, even though Ushinosuke had reached the age of fifteen, Michitō did not attempt to transfer headship of the clan to him.  Dissatisfied with the situation, Ushinosuke planned to appeal to Tokugawa Iesyasu, but, upon hearing this news, Michitō sent an assassin and had Ushinosuke killed. 

Within less than one-half year after the assassination, on 12/12 of 1607, Michitō suddenly died in Fushimi at the age of thirty-eight, and it was said to be divine punishment for the killing of his nephew.
