The deity enshrined at Inokami Shrine is the god of water, Minakatamenomikoto. The date of its establishment is unknown, but there is a sign from the second year of Kanpo (1742). The shrine's believers prayed for rain during times of water shortage. Every year on the first Sunday of July, a portable shrine is carried through the river for a seasonal event. Until this was established, women were prohibited from participating. Following the portable shrine, there is a ritual of throwing rice cakes, and local people set up stalls.
