## Biography

He was born in Omura, November 25, 1618, as the eldest son of the second lord of the domain, Ōmura Sumiyori. Her childhood name was Matsushiyo. Her mother is the adopted daughter of Yorinao Matsura (her biological father is Kusumoto Emon, a vassal). His legal wife is Matsu, the daughter of Katsunaga Itami.
His father, Sumiyori, died young at the age of 28, in November 1619, and the Omura domain, which officially had no heir, was in crisis.
Sumiyori once had a child in Kunimoto, but for reasons that are unclear, he ordered the child to be aborted. However, the chief retainer, Junkatsu Omura He secretly caused her to give birth and persuaded Sumiyori to spare the life of the child, Matsuchiyo. Matsuchiyo, who was an orphan but had not been notified to the shogunate, was pretended to be adopted by Sumiyori, and senior vassals tried to persuade neighboring daimyo and the shogunate. Junkatsu and Tominaga Tadakiyo left Omura on December 10 of the same year with Matschiyo, who was only 2 years old, and arrived in Edo, in 1620), with Matschiyo in the Shogunate, filed suit for inheritance. At this time, Junkatsu was offered a position as a shogun's vassal by the Roju, but he refused and persistently appealed for the continuation of the lord's family. The story of collection dates back to 7th year of Kan'ei (CE 1630). Junkatsu firmly denies this. On May 15 of the same year, Matsuchiyo's succession to the family headship was approved. As a result of this feat, Junkatsu and his descendants were granted permission to use the same family crest as their master family and the status of Otoshiyori. Yorinao Matsura, the mother's adoptive father, was also given the surname Omura, and from then on, both families were treated as branch families of the feudal lord's family throughout the Edo period.
In the same year, the domain carried out the construction work to rebuild the stone walls of Osaka Castle, which had been ordered at the time of the previous generation, Sumiyori. In the 5th year of Kan'ei (1628), he was ordered by the Shogunate to take custody of the Dutch prisoners of the Tiowan Incident, and took charge of the prison.
In the 8th year of Kan'ei (1631), 42,730 koku was found in the territory, compared to 27,900 koku in front. More than half of these areas are directly controlled by feudal domains. However, the domain's finances were in trouble due to expenses incurred in Nagasaki official duties and in Edo, and they made ends meet by borrowing money from relatives of feudal lords and receiving money from vassals.
Due to illness, he was unable to participate in the Shimabara Rebellion, which occurred at the end of October (December 11, 1637), and Junkatsu led his troops to guard Nagasaki.
However, Sumonobu died childless, in May of 1650, at the age of 33, and the Omura domain once again faced the threat of change. There was some debate within the family, but Matsu's legal wife, Matsu's brother, Ōmura Suminaga (Itami Katsunaga's fourth son), became a terminally adopted child. The crisis is over.
