Oarai Isosaki Jinja

History

Oarai Isosaki Jinja is an ancient shrine traditionally said to have been founded in 856. According to legend, one night the local gods descended in a blaze of light onto a rocky outcrop along the Oarai coastline, and by imperial order a shrine was built on the site to commemorate the miracle. The shrine buildings were destroyed by fire amid the conflicts of the medieval period, but reconstruction began in the Edo period under the order of Tokugawa Mitsukuni, the second lord of the Mito domain, and the shrine buildings seen today were completed under the third lord, Tsunaeda.

The shrine enshrines Onamuchi no Mikoto (Okuninushi) and Sukunahikona no Mikoto, two deities revered as gods of nation-building and medicine, and long honored here as guardians watching over the sea at Oarai. Perched on a bluff facing the Pacific, the shrine commands a striking view over the ocean and its famous torii gate below.

Highlights

The single greatest highlight of Oarai Isosaki Jinja is the “Kamiiso no Torii,” a gate standing on a rocky outcrop just offshore. Tradition holds this very rock to be the spot where the shrine’s deities first descended, and the sight of the torii standing firm against the crashing waves of the Pacific is a truly awe-inspiring scene that draws worshippers and visitors alike. Every New Year’s Day, the head priest and other shrine officials climb down onto the rock itself to perform the “Hatsuhinode Hohai-shiki,” a ceremony venerating the year’s first sunrise.

The Kamiiso no Torii has also become widely known as a pilgrimage destination for fans of the anime Girls und Panzer, which is set in the town of Oarai, and the shrine grounds now hold numerous ema plaques decorated with art from the series. The surge of fans visiting Oarai following the anime’s popularity has brought considerable energy to local tourism. The shrine’s 16-meter-tall first torii gate, which spans the prefectural road at the entrance, is another highlight, ranking among the largest of its kind in the Kanto region.

Visiting Tips

The gates are open 5:30–18:00 from April to September, and 6:00–17:00 from October to March. Goshuin are available 9:00–17:00, for ¥500. Free parking is available on the grounds, but it fills up quickly around New Year’s and sunrise, so an early arrival is recommended. Sea spray can reach the area around the Kamiiso no Torii, so watch your footing when visiting.
