The shrine's own account says it was founded on the ninth of September, in the third year of the Keiun era, in the early eighth century, during the reign of Emperor Monmu. The place was then called Arakura Township, in Yatsushiro County of Kai Province. The shrine was meant to enshrine the guardian deity of the Fuji Kitaguchi township, which is today's Fujiyoshida. The next great chapter comes in the year 807. Mount Fuji erupted violently, and on the twenty-second of August an imperial envoy came from the court to perform a ceremony to calm the volcano and keep the land safe. According to the shrine's tradition, Emperor Heizei then bestowed on this shrine the title Sangoku Daiichi San, meaning The First Mountain of the Three Provinces. Heizei also presented a gold offering wand, a ceremonial mask for the envoy, and an inscribed tablet in his own hand. That tablet is the one now displayed on the great torii. The title is a grand phrase. The three countries meant India, China and Japan, so it was a way of calling Fuji the greatest mountain in the known world. The envoy's mask is now kept in the Fujiyoshida City Museum.
