in a book named ' battle fields of zohyo ' (common soldiers ) (published by the asahi shimbun company in 1995 ) written by hisashi fujiki , he presented a theory that the image of the uesugi army was different from the real kenshin uesugi who was usually reputed as a loyal person based on a phrase that ' kenshin was a savior of the people in echigo province because he planned and implemented venture business called war in other provinces , stricken villages in the kanto region , which were battlefields , suffered looting and he had seen hell ,' this sensational theory of ' working away from home ' was supported by many experts and widely spread among the public . 藤木久志は著書である『雑兵たちの戦場』（朝日新聞社・1995年刊）で「上杉謙信は越後の民衆にとっては他国に戦争と言うベンチャービジネスを企画実行した救い主であるが、襲われた関東など戦場の村々は略奪を受け地獄を見た」と、通常言われる義人・上杉謙信像とは別の上杉軍の姿こそが実態であったとし、このセンセーショナルな「出稼ぎ」説は多くの識者から支持を得て広く世間に浸透した。
