Legends and Mysteries: The Kamiiso-no-Torii where the kami descended
The symbol of Oarai Isosaki-jinja is undoubtedly the Kamiiso-no-Torii (Kamiiso, meaning ‘Kami’s Shore’), standing on a rocky reef in the sea. This spot is revered as the sacred place where the enshrined kami, Onamuchi-no-mikoto and Sukunahikona-no-mikoto, are said to have descended.
The Legend of the Divine Descent
According to the Montoku Jitsuroku, a historical record from the Heian period, on the night of Saiko 3 (856 AD), the coastal rocks shone brightly, and two kami descended. The kami are said to have declared, “We once created this land and then departed, but we have returned once more to save the people.”
Behind the Scenes: The Paired Sakatsura Isosaki-jinja
In fact, Oarai Isosaki-jinja has a ‘sibling’ jinja: Sakatsura Isosaki-jinja, located in Hitachinaka City. It is believed that Onamuchi-no-mikoto descended in Oarai and Sukunahikona-no-mikoto in Sakatsura, forming a single faith between these two jinja. Visiting both jinja is said to bestow stronger divine blessings.

Mystery of the Magnificent View: Why Does the Torii Remain Undamaged?
The torii gate stands on a rocky outcrop relentlessly battered by the rough waves of the Pacific Ocean. It’s astonishing that it maintains its form even during typhoons and severe storms. The current torii was built of concrete in 1963 (Showa 38), but its continued presence in such a harsh environment truly evokes the strength of a sacred barrier (kekkai) protecting a divine realm.
Especially around the winter solstice, the sunrise can sometimes be seen perfectly framed within the torii, drawing photographers and worshippers from across the country seeking this mystical moment.

Anime Pilgrimage: Featured in ‘Girls und Panzer’
Oarai Isosaki-jinja is also very famous as a pilgrimage site for the popular anime ‘Girls und Panzer’ (commonly known as ‘Garupan’).
Famous Scenes from the Series
In the movie version, a shocking scene features tanks hurtling down the jinja’s steep stone steps. These steps actually exist at the jinja, and looking down from the top reveals just how incredibly steep they are.
Giant Ema and Votive Ema
Within the jinja grounds, a giant ema (votive tablet) featuring Garupan characters is displayed, alongside numerous ema with illustrations of professional-level quality, dedicated by fans (affectionately known as ‘Garupan Ojisan,’ or ‘Garupan Uncles’). The jinja warmly embraces this anime collaboration, creating a rare space where traditional faith and modern subculture brilliantly merge.

Key Points for Worship and Insider Stories
Warship Naka’s Monument to Loyalty: Within the jinja grounds stands a monument dedicated to the light cruiser ‘Naka,’ which played an active role in the Pacific War. The shrine onboard the Naka was established with a divided spirit (bunrei) from Oarai Isosaki-jinja, making this an important spot for ‘Kantai Collection’ fans as well.
Nade-Usagi (Patting Rabbit) for Good Fortune: In connection with the enshrined kami Onamuchi-no-mikoto (also known as Okuninushi-no-kami), there is a rabbit statue in the jinja grounds, themed after the ‘White Hare of Inaba’ legend. It is believed that patting this statue brings good luck and recovery from illness.
Oarai Isosaki-jinja is a fascinating place where the ancient world of mythology intersects with modern anime culture. Why not listen to the sound of the waves while gazing at the Kamiiso-no-Torii and feel the breath of history?
