Nobuyoshi served the Uesugi clan of Echigo province and was given Ômori castle. He blundered a diplomatic mission to the Tokugawa in 1600 and afterwards fled Echigo. He entered the service of the Tokugawa and was given some land and a stipend in Shimotsuke province. He managed to disgrace himself again in the fighting at Osaka Castle (1615) through inept conduct, and was demoted as a result.
