It is said to have begun in the mid-Heian period (1087-1093) when Murakami Akikiyo, who was exiled to Shinano Province, visited this place and enshrined "Hachiman Okami," the god of military fortune and longevity. The offering is a set of two items: a goshuin (red seal with a three-color crest) and a history document. During the Battle of Kawanakajima on September 10, 1561, in the Sengoku period, Takeda Shingen, who revered Hachiman Okami, set up camp at this shrine, and the precincts became the site of a one-on-one duel with Uesugi Kenshin.
