Basic Information
Name: Okiguu (Okinogu)
Location: 44 Ōnoyama-chō, Naha City, Okinawa Prefecture (within Ōnoyama Park)
Enshrined Kami: Tenjukume Ryuuguuou Onkami (often identified with Amaterasu Omikami), Izanami-no-Mikoto, Hayatamao-no-Mikoto, Kotosakao-no-Mikoto, and others.
History: Okiguu is one of the “Ryukyu Hassha” (Eight Shrines of Ryukyu), which were specially revered by the Ryukyu kings. It is said to have been founded in 1451, during the reign of King Shō Kinpuku, and has been worshipped since ancient times as a kami for safe voyages and national peace.
The Legend of the “Radiant Sacred Tree” that Appeared from the Sea
The origin of Okinogu is marked by a truly mystical episode. In the mid-15th century, a mysterious light appeared nightly in the waters of Naha Port. The king, witnessing this, ordered fishermen to investigate, and they retrieved a “radiant ancient tree” from the sea. The king revered this tree as the “Sacred Tree of Horai” (a legendary island of immortals), and it is believed that the construction of a jinja to enshrine it marked the origin of Okinogu. This sacred tree became a spiritual anchor for people, worshipped as “Funadamagami” (a kami protecting ships), safeguarding the safe voyages of tribute ships heading to China and Satsuma.
The Mystery of the “Oracle” that Guided Post-War Reconstruction
Okinogu was once located near Naha Port, and its main hall was so beautiful that it was designated a National Treasure in 1938 (Shōwa 13), but tragically, it was destroyed by fire during the Battle of Okinawa. After the war, its reconstruction was guided by an “oracle” bestowed upon a single man. Higa Shinju, who would become the first post-war chief priest, received a divine message: “Rebuild Okinogu.” Following this guidance, he arrived at Tentōzan, a hill within Ōnoyama, which is the current location of the jinja. Based on the mysterious message, “The origin of the former sacred tree lies on this Tentōzan,” the jinja was relocated and rebuilt at its current site in 1975.
Tentōzan (Kuganmui), Naha’s Most Powerful Power Spot
Ascending the stairs behind the haiden (worship hall), you will find a small hill called Tentōzan. This place has been called “Kuganmui” (Golden Forest) since ancient times and is considered a sacred site where Amaterasu Omikami descended, possessing one of the highest levels of spiritual energy in Okinawa Prefecture. At the summit stands a stone monument inscribed with “Tenjukume Ryuuguuou Onkami,” and the panoramic view of Naha city from there is breathtaking. Despite being in the heart of the city, this spot is enveloped in a sacred tranquility, with the air feeling crisp and still.
“Kami’s Theme Park”? Modern Appeal and Behind-the-Scenes Stories
While Okinogu boasts a solemn history, it also has an approachable side, to the extent of being called a “Kami’s Theme Park.” For instance, there is a cafe on the grounds called “Oki no Chaya” where visitors can relax after their worship. The jinja hosts diverse events such as yoga classes, hula dancing, and sometimes even DJ events, showcasing a modern jinja that, while preserving tradition, is open as a place for the local community. Furthermore, Okinogu holds a characteristic as a “sacred site for karate,” with a monument honoring Okinawan karate and practitioners sometimes offering demonstrations.
Pilgrimage Information: Anime “The Aquatope on White Sand”
Okinogu and its surrounding area (Ōnoyama Park) are also known as a pilgrimage site for the anime “The Aquatope on White Sand,” which is set in Okinawa. In the latter half of the story, particularly in episodes set in Naha (around episodes 14 and 15), the jinja and park served as models for scenes visited by the protagonists. Many fans can be seen coming on “sacred site pilgrimages.” It is a spot where you can experience firsthand the beautiful red-tiled shrine buildings and the peaceful scenery within the park, just as depicted in the anime.
