Also known as: Yamaura Kunikiyo (山浦国清), Yamaura Kagekuni (山浦景国)

Eldest son of Murakami Yoshikiyo, he and his father sought sanctuary with Uesugi Kenshin in 1553 from Takeda Shingen and became his vassals. He later became the head of the Yamaura-Uesugi family and changed his name to Yamaura Kunikiyo. He fought in many of Kenshin's wars, including the Battles of Kawanakajima.

He supported Uesugi Kagekatsu in the Otate no Ran after Kenshin's death. Kagekatsu bestowed the Kage (景) character on him for his merits in the war, whereupon he changed his name to Yamaura Kagekuni.

In 1582 he became the master of Kaidu Castle and recovered his father's old fief. In 1590, he served in the vanguard of the Uesugi army in the attack against Odawara by Toyotomi Hideyoshi. He also fought in the Battle of Sekigahara in 1600, but his circumstances after that are unknown.
