垂仁天皇
According to the "Nihon Shoki", around 2000 years ago the divine Yamatohime-no-mikoto, daughter of the Emperor Suinin, set out from Mt. Miwa in modern Nara Prefecture in search of a permanent location to worship the goddess Amaterasu, wandering for 20 years through the regions of Ohmi and Mino. Her search eventually brought her to Ise, in modern Mie Prefecture, where she is said to have established Naikū after hearing the voice of Amaterasu saying "(Ise) is a secluded and pleasant land. In this land I wish to dwell." Before Yamatohime-no-mikoto's journey, Amaterasu had been worshiped at the imperial residence in Yamato, then briefly at Kasanui in the eastern Nara basin. When Princess Yamatohime-no-mikoto arrived at the village of Uji-tachi, she set up fifty bells to designate the area as enshrined for the goddess Amaterasu, which is why the river is called the Isuzu, or "fifty bells".
