Ōminato Shrine, located on Ōshima, known as the "Island of the Gods" in Sakai City, is said to have been established in the Hakuchi era (650) and is an ancient shrine listed in the Engishiki. In the past, when foreign warships arrived, the enshrined deity, Anashima Ura Miho Daimyōjin, manifested a divine miracle at the hill of Matsugahara in the present-day Jin-ga-oka area and drove away the barbarians. This event later reached the ears of Emperor Monmu, and in the first year of Taihō (701), three imperial envoys were dispatched, and a shoryo (shrine territory) of over 3,700 koku was donated. From this time on, the shrine was revered as the god of archery, and people began to dedicate bows and arrows when visiting and praying. Only goshuin (temple seals) are available. From the sightseeing boats departing from Tōjinbō, you can see the red torii gate of Ōminato Shrine, the cliffs, and the "columnar joints" of rhyolite formed by wave erosion. In addition, the Ōshima Bridge is famous for its long, vermilion bridge, and the red bridge and the blue sea create a beautiful contrast, making it a perfect spot for taking photos.
