Mashita Nagamori

Who was Mashita Nagamori?

Mashita Nagamori was a daimyo in Azuchi-Momoyama period, and one of the Go-Bugyō appointed by Toyotomi Hideyoshi. Also called Niemon or by his court title, Uemon-no-jō.

Nagamori was born in Nakashima-no-kori, Mashita-mura, Owari Province or Asai-gori, Mashita-go, Ōmi Province and served Hashiba Hideyoshi when he had been a retainer of Oda Nobunaga. Since he shined with domestic affairs such as Cadastral Surveys by Hideyoshi and diplomatic negotiations with Uesugi Kagekatsu, Hideyoshi gave him 200,000 koku at Koriyama Castle, Yamato Province and appointed him to five bugyo. Nagamori took part in the Battle of Bunroku and the Battle of Keicho.

After Hideyoshi died, in 1600, Nagamori took part in Ishida Mitsunari's force when he put up Mōri Terumoto who was a member of the council of Five Elders and raised their army to Tokugawa Ieyasu. However, Nagamori was involved in an intrigue with Ieyasu. He didn't take part in the Battle of Sekigahara on October 21 and held a fort at Osaka Castle. After the Battle, Ieyasu seized Nagamori's domain, but helped his life and left him to Kōriki Kiyonaga who was a retainer of Ieyasu and lord of Iwatsuki Castle, Musashi Province.
