Eino Jinja Shrine is a historic Shinto shrine in Eino, Shiranuhimachi, Uki City, Kumamoto Prefecture. Formerly classified as a village shrine, it has long been rooted in the local community. The shrine is particularly well known for its torii gate standing in the waters of the Shiranui Sea, also known as the Yatsushiro Sea.
The striking sight of the gate surrounded by the sea creates a majestic landscape where nature and spirituality come together. The shrine offers visitors a quiet, sacred atmosphere and is a distinctive destination for those interested in Japanese religious traditions, local legends, and coastal scenery.
According to tradition, Eino Jinja Shrine was founded in 713, during the Wadō era, at the request of Emperor Genmei. It was established to pray for peace and stability throughout the country.
Local shrine records tell of a sea deity known as Wadatsumi-no-kami who arrived from a distant place riding on the back of an ei, a ray-like marine creature. This legend is closely connected with the origin of the shrine’s name and the distinctive geography of the surrounding area.
Mount Kamada lies to the north of the shrine. When viewed from the Shiranui Sea, the shape of the land is said to resemble a ray lying with its body toward the mountain. The location of the shrine corresponds to the position of the creature’s tail.
This association is said to have given the place its name, Eino, written with characters meaning “eternal tail.” The shrine is also known by the alternative name Tsurugi Jinja, or “Sword Shrine,” because the tip of the ray’s tail is said to resemble a sharply pointed sword.
Another ancient legend tells of a gigantic ray carrying Wadatsumi-no-kami across the Shiranui Sea. The creature attempted to cross the Uto Peninsula, where the shrine is located, but its journey was blocked by a huge fishing net. Unable to proceed, it remained in the area.
According to the story, the shrine was subsequently built at the tip of the ray’s tail. The legend is also said to explain the origins of several nearby place names associated with nets, including Amatsu, Amibiki, and Amida.
Among some local parishioners, the ray is revered as a creature belonging to the deity, and a tradition of not eating rays has been observed. Eino Jinja Shrine is particularly associated with prayers for recovery from gastrointestinal illnesses, and worshippers visit to seek the deity’s blessings.
The torii gate standing in the sea enhances the shrine’s mysterious character. The combination of the sacred structure, the surrounding water, and the legends associated with the ray gives the shrine a distinctive place in local religious culture.
Eino Jinja Shrine holds the Hassaku Festival every year on the first day of the eighth month of the traditional lunar calendar. The date coincides with the season when the mysterious natural phenomenon known as Shiranui is said to appear.
Many visitors come to the shrine’s elevated grounds in the hope of seeing Shiranui from the hill. With its scenic views over the sea, the shrine becomes especially lively on the festival day, when local residents and visitors gather in an atmosphere of reverence and celebration.
The shrine enshrines several deities associated with protection, learning, nature, and the local community.
Wadatsumi-no-kami (Tamayori-hime-no-mikoto): The principal deity, worshipped as a guardian of the area.
