Ooarai Isosaki Shrine

Oarai Isosaki Shrine is a venerable ancient shrine founded in the Heian period, enshrined on a hill at Oarai Cape in Oarai Town, Higashiibaraki District, Ibaraki Prefecture. It is said to have been established in 856, during the 3rd year of the Saikyo era, and records in the contemporary Nihon Montoku Tennō Jitsuroku state that the enshrined deities, Ōkuninushi-no-Mikoto and Sukunahikona-no-Mikoto, descended upon the sacred rocky shore of Tōkai. These two deities are believed to have worked together to enrich the land, promote medicine and industry, and save the people from illness, and they are widely revered as gods of medicine, good fortune, matchmaking, and wisdom, strength, and virtue.

Ōkuninushi-no-Mikoto is affectionately known as “Daikoku-sama,” a benevolent deity who bestows good fortune and blessings. He is also famous for appearing in the myth of “The White Hare of Inaba,” and, from the legend in which he healed an injured white hare, he is deeply worshipped as a god of medicine. Sukunahikona-no-Mikoto is a small-bodied deity said to have served as the model for Issun-bōshi, and is regarded as a founding deity of medicine who spread medical knowledge and hot-spring therapy. It is said that the two deities descended here once again at a time when smallpox and famine were widespread and many people were suffering, and that they “returned to save the people.”

The shrine buildings were destroyed in warfare during the Sengoku period, but in 1690, Tokugawa Mitsukuni, the second lord of the Mito domain, ordered their reconstruction, and the work was completed in 1730 during the reign of the third lord, Tokugawa Tsunaeda. The present main hall, worship hall, and Zuishin Gate were rebuilt in the mid-Edo period, and as valuable structures that preserve the architectural style of the early Edo period, they are designated cultural properties of Ibaraki Prefecture. The main hall is a thatched one-bay nagare-zukuri structure, and the worship hall is built in the irimoya style with delicate openwork carving. Surrounded by a sacred grove, the grounds exude the dignity of the Mito domain era and a serene atmosphere.

To the east of the shrine, on a rocky reef facing the Pacific Ocean, stands the “Torii of Kamiiso,” said to mark the place where the enshrined deities descended. Bathed in crashing sea spray, the torii has a mystical presence, and at sunrise it creates an especially enchanting scene. During the winter solstice, many worshippers and photographers visit in hopes of capturing the breathtaking sight of the torii aligned perfectly with the rising sun. It is said that Tokugawa Mitsukuni also praised this view.

The water that wells up within the grounds has long been called “Mesarashi-no-I,” or “the eye-cleansing well,” and was known as a sacred spring believed to be effective for eye ailments. In the Edo period, coastal seawater therapy was also popular, and the area bustled with people praying for recovery from illness. During the Great East Japan Earthquake in the Heisei era, a tsunami swept in, yet there were no human casualties around the shrine, and it is said that sacred water sprang forth once again. Many people visited, feeling the protection of the gods.

In addition, the grounds include the Oarai Marine Museum, which exhibits old fishing boats, fishing gear, materials related to the fisheries industry, and specimens showing the evolutionary process of whales. It is a popular facility where visitors can learn about Oarai’s history of living together with the sea.

In recent years, the shrine has also attracted attention as a setting for the anime Girls und Panzer. The grounds are lined with large zodiac ema plaques and playful “ita-ema” plaques decorated with characters, and fans visit as pilgrims to this sacred site.

Oarai Isosaki Shrine is a divine power spot said to bring blessings for romantic fulfillment, household safety, good luck, protection from misfortune, and maritime safety. With its sacred scenery, including the Torii of Kamiiso, and shrine buildings that preserve the elegance of the Edo period, this place soothes the hearts of visitors and leaves a deep impression.
