Harunobu advanced to Suwa Province for the first time with the banner, famous of its slogan "Hurin-kazan". After defeating Suwa, he advanced to Shinano Province. Then with the desire to obtain the province of Echigo, Harunobu fought Kawanakajima Battles with the military load Uesugi Kenshin for several times. After having gained the land of Suruga, he proceeded to the westward for the control of the strategic west routes. On his way to the west dreaming for the control of the country, however, he suffered from illness and ended his life of 53 years with an unfulfilled desire to be the ruler of Japan.
