Uesugi Norikatsu served as a bushi during the Sengoku period. He was the head of the Ōgigayatsu-Uesugi family.
Although considered a member of the Ōgigayatsu-Uesugi family, Norikatsu originated from either the Fukaya-Uesugi or Yamauchi-Uesugi families and may have been raised like a son of the Ōgigayatsu-Uesugi.
Initially, he used the name of Nanasawa Shichirō and was a rōnin, or wandering samurai, in the Ouu region.
In the wake of the death of Uesugi Tomosada, the son of Tomooki, at the Siege of Kawagoe Castle ended the bloodline of the Ōgigayatsu-Uesugi family, Norikatsu was backed by Ōta Sukemasa to inherit the vestiges of the family.
In 1559, after Sukemasa took Matsuyama Castle in Musashi Province away from Hōjō Ujiyasu, Norikatsu entered at its new lord. Two years later, however, he was surrounded by the allied forces of the Hōjō and Takeda and surrendered. Uesugi Terutora (later known as Uesugi Kenshin) headed out in support of Norikatsu, but, after arriving at Ishido Castle, became upset upon learning that Norikatsu had surrendered whereupon he cut-down the son of Norikatsu whom he had earlier taken as a hostage.
