The Jinbo family of Etchû Province, at one time possible retainers of the Hatakeyama, were almost constantly at war with local rivals such as the Shiina and the ikko-ikki. Defeated by Nagao Tamekage in 1520, they enjoyed a brief period of local power under Jinbo Nagamoto but when Uesugi Kenshin sided with Shiina they lost their castle, Toyama, and at length became Uesugi vassals.
