Niwa Nagatomi was a Japanese daimyo of the late Edo period.
Background
Nagatomi, known in his childhood as Kakuzō (覚蔵) and later Bankichi (蕃吉), was born in his family"s Edo residence in 1803. He was the eldest son of the previous daimyo, Niwa Nagaaki. At age 11, due to the death of his father, he inherited the family headship, becoming 10th generation lord of Nihonmatsu han.
Career
Nagatomi relied heavily on his Karō, the famed Niwa Takaaki. He encouraged his retainers to excel in the martial and literary arts, and to that end, sponsored the opening of the domain"s official school, Keigakukan (敬学館). In 1822, during economic issues prior to that, he deployed domain forces to put down a peasant uprising.
He also helped revive the domain"s economic situation following a seven-year string of famines during the Tenpo era.
His domain, together with Aizu han, was in charge of security at the Futtsu artillery emplacement during the Perry Mission. Nagatomi"s children went on to become famous in the Bakumatsu period.
Nagatomi held the title of Sakyō-dayū (左京太夫), and the junior 4th court rank, lower grade (jū shi-i no ge 従四位下).
