Izanagi Jingu Shrine is a historic Shinto shrine located in Taga, Awaji City, on Awaji Island in Hyogo Prefecture. It is traditionally regarded as one of Japan’s oldest shrines and is identified as the ichinomiya, or highest-ranking shrine, of the former Awaji Province. In ancient shrine records, it is listed as a Myojin Taisha, a shrine of particularly high status. Today, it is also designated as a special shrine under the Association of Shinto Shrines.
Affectionately known by local residents as Ikku-san or Izanagi-san, the shrine has deep connections to Japanese creation mythology. On January 15, the traditional Little New Year, it hosts the Kayu-ura Festival, a rice porridge divination ritual, alongside the Awaji Agriculture, Forestry, and Fisheries Festival. On April 25, 2016, the shrine was recognized as part of a Japan Heritage designation celebrating the island’s cultural traditions.
The shrine enshrines two major deities of Japanese mythology: Izanagi-no-Mikoto and Izanami-no-Mikoto. According to the ancient chronicles, these divine figures played central roles in the creation of the Japanese islands and the birth of numerous other deities.
Originally, the shrine enshrined Izanagi-no-Mikoto alone. Izanami-no-Mikoto was formally enshrined alongside him in 1932, bringing the two mythological partners together at this sacred site.
The development of the belief in Izanagi-no-Mikoto and his connection to the imperial mythology of ancient Japan has been the subject of various historical theories. One interpretation suggests that the belief in Izanagi as an ancestor of the imperial ancestral deities began to develop around the mid-seventh century. Seafaring communities from Awaji Island, which supplied food to the imperial court, may have helped transmit these religious traditions.
The origins of Izanagi Jingu are associated with the ancient chronicles Kojiki and Nihon Shoki, which recount the creation of Japan and the birth of the gods. According to tradition, after completing the work of creating the islands and deities, Izanagi-no-Mikoto settled in Taga on Awaji Island, said to be the first island he created. This place is also believed to be where the deity spent his final days, forming the foundation of the shrine’s sacred history.
References in ancient historical records suggest that the shrine has been associated with Japan’s religious traditions since early times. The Nihon Shoki mentions deities called Izanagi-no-Kami and Shima-no-Kami during the reigns of Emperor Richu and Emperor Ingyo. These references are generally interpreted as referring to the deity worshipped at Izanagi Jingu.
By the late Heian period (794–1185) and early Kamakura period (1185–1333), the shrine had established its position as the ichinomiya of Awaji Province. It became a central place of worship for the island and its surrounding communities.
During the medieval period, the shrine received support from provincial government officials and local rulers. Historical records mention ceremonies such as the Hokke-e and Sakura-e, held under the supervision of the provincial administration. The presence of an associated Buddhist temple also reflects the close relationship between Shinto and Buddhism in premodern Japan.
In the late medieval period, the Tamura family took responsibility for managing the shrine. During this era, the institution underwent a period of conversion to Nichiren Buddhism, illustrating the changing religious and political circumstances of the time.
During the Edo period (1603–1868), the shrine was supported by the Hachisuka family, lords of the Tokushima Domain, who provided an annual land stipend equivalent to ten koku of rice.
In 1870, the authorities of Meito Prefecture designated Izanagi-no-Mikoto as the shrine’s deity. The shrine was ranked a National Shrine of the Middle Grade in 1871 and elevated to the status of a Grand National Shrine in 1885. In 1948, it was included on the Association of Shinto Shrines’ special shrine list. Its current name, Izanagi Jingu, was officially adopted in 1954.
On January 17, 1995, the Great Hanshin-Awaji Earthquake caused serious damage to the shrine, including the collapse of its first torii gate. Thanks to donations from parishioners and local supporters, the gate was rebuilt in November of the same year in the shinmei style, characterized by a simple, straight-lined design. The shrine continues to be carefully maintained by the local community, preserving its longstanding religious traditions.
The main sanctuary, or honden, was rebuilt in 1879 and relocated to its present position in 1881. It features a three-bay nagare-zukuri architectural design, a traditional shrine style distinguished by an extended, gently curved roof over the entrance. The sanctuary is connected to the offering hall by a covered roof.
The offering hall, known as the heiden, and the middle gate were constructed in 1881. These buildings form part of the shrine’s sacred ceremonial space and play important roles in religious observances.
The worship hall, or haiden, was rebuilt in 1882. It features an irimoya-style roof, combining a hipped roof with gabled sections, covered with copper sheets. The building also serves as a dance hall for traditional ritual performances and is where visitors offer prayers.
The mikoshi storehouse was built in 1808 by Hachisuka Haruaki, lord of the Tokushima Domain. It houses the shrine’s sacred portable palanquins, which are brought out during festivals and ceremonial processions.
A large camphor tree on the grounds was planted on November 30, 1922, by the future Emperor Showa when he was still Crown Prince. The tree continues to grow and stands as a living reminder of the shrine’s connections with the imperial family.
The shrine grounds contain a place where visitors can pay their respects from afar to Ise Jingu, one of Japan’s most important Shinto sanctuaries. According to the shrine’s tradition, Ise Jingu lies due east along the same line of latitude, linking the two sacred sites in the landscape.
This pond is believed to preserve traces of a moat that once surrounded the mausoleum associated with Izanagi-no-Mikoto’s final resting place. Traditionally, worshippers released carp into the water when praying for the recovery of someone who was ill, and released turtles in gratitude when their prayers were answered.
Several auxiliary and subsidiary shrines stand within the precincts. The Sayū Shrine enshrines Amaterasu-Omikami, the sun deity, and Tsukuyomi-no-Mikoto, the moon deity. Kashima Shrine and Sumiyoshi Shrine are associated with protection and agricultural blessings.
At the base of the enormous paired camphor tree known as the Meoto Okusu, or Husband-and-Wife Camphor Trees, stands Iwakusu Shrine. The site is particularly revered by those praying for conception and safe childbirth.
The Meoto Okusu is one of the shrine’s most remarkable natural features. The paired camphor tree has an estimated age of around 900 years and was designated a Hyogo Prefecture Natural Monument in 1973. Its immense trunk and intertwined roots have made it a powerful symbol of longevity, connection, and family blessings.
Nine sacred statues preserved at the shrine are designated Tangible Cultural Properties by Awaji City. These objects are valued as material expressions of the shrine’s long history and the religious traditions that have been passed down through generations.
Izanagi Jingu is a place where Japanese creation mythology, centuries of religious history, traditional architecture, and remarkable natural landmarks come together. From its revered deities and historic sanctuary buildings to the ancient camphor tree and sacred pond, the shrine offers visitors a meaningful introduction to the spiritual heritage of Awaji Island. Its enduring role in local life makes it an especially rewarding destination for travelers interested in Japan’s mythology, culture, and traditional beliefs.
