Izanagi Shrine — 伊弉諾神宮

Izanagi Shrine sits at what devotees call the centre of the Japanese cosmos — not metaphorically, but geometrically. The shrine marks the spot where Izanagi no Mikoto, the father deity who formed the islands of Japan, is said to have spent his final days after creating the world with his wife Izanami. When you draw straight lines from this shrine in Awaji Island to other major sacred sites — Ise Grand Shrine to the east, Takachiho to the southwest, Izumo Taisha to the northwest — they form near-perfect alignments with solstice sunrise and sunset angles. Whether this is ancient design or historical coincidence, the geometry has made this small shrine in rural Hyōgo Prefecture the subject of persistent cosmological fascination.

The shrine’s foundation myth is Japan’s foundation myth. According to the Kojiki and Nihon Shoki, after Izanagi returned from the underworld and performed purification rites that gave birth to Amaterasu and other kami, he retired to Awaji Island — the first island he and Izanami had created — and built a residence here. The current shrine was formally established during the Heian period, though the site itself has been venerated since at least the 7th century. The Engishiki records from 927 CE list it as Awaji’s most important shrine. In 1868, during the Meiji Restoration, it was elevated to the status of kanpei-taisha (官幣大社), a shrine of the highest imperial rank. The shrine underwent major reconstruction after the 1995 Great Hanshin Earthquake, which caused significant structural damage despite the building’s sacred reputation.

Izanagi no Mikoto (伊弉諾尊) and Izanami no Mikoto (伊弉冉尊) are enshrined together, the primordial couple who, according to mythology, stood on the Floating Bridge of Heaven and stirred the ocean with a jeweled spear until drops formed the first island. They then descended and gave birth to the islands of Japan and numerous kami. Izanagi is associated with creation, light, purification, and longevity — he is the deity who washed away death itself when he bathed after visiting Yomi, the underworld. The shrine treats him specifically in his retirement aspect: the creator at rest, the divine father who completed his work and withdrew to contemplate it. Prayers here often concern life transitions, completion of major endeavors, and peaceful aging.

The shrine’s central legend involves two enormous camphor trees. After Izanagi built his residence on Awaji, he planted two camphor saplings side by side to represent himself and Izanami, reunited symbolically after her death separated them. These trees grew intertwined for over a millennium until a typhoon in the Meiji era destroyed one. The surviving tree, now over 900 years old, measures nearly 30 meters in circumference and is designated a National Natural Monument. Called the Meoto no Ōkusu (Husband-and-Wife Great Camphor), its massive exposed roots form a natural enclosure where couples come to pray for harmony. Local tradition holds that to walk around the tree clockwise brings marital fortune, while walking counterclockwise while unmarried ensures you’ll find a spouse. The tree is so ancient that its hollow trunk can accommodate a small shrine inside its own body.

The main worship hall follows the shinmei-zukuri style — plain, unpainted cypress with a thatched roof — echoing the architectural form of Ise Grand Shrine, appropriate for a deity of Izanagi’s genealogical position. The shrine grounds are modest in scale but dense with symbolic features. A sacred pond called Hōmotsu Pond contains ancient foundation stones said to be from Izanagi’s original dwelling. The Kikka Suimon (Chrysanthemum Water Gate) feeds water that purportedly never freezes, even in winter, attributed to residual divine warmth from Izanagi’s presence. Near the main hall stands a large boulder marked with shimenawa (sacred rope), called the Saiichi no Ishi — the “Stone of the First Ritual” — supposedly where Izanagi first purified himself after returning from the underworld. The shrine’s treasure hall displays ancient mirrors and swords, though the most powerful artifact is the land itself: the plot where the creator chose to die.

• Reitaisai (April 22) — The annual grand festival commemorating Izanagi’s retirement, featuring sacred kagura dance depicting the creation myths and processions of mikoshi through Awaji’s northern villages.
• Kuni-umi Matsuri (May 3) — The “Nation-Birth Festival” celebrates the mythological creation of Japan with performances, traditional music, and offerings of local produce representing the abundance Izanagi and Izanami brought into being.
• Yusai (Summer Purification, June 30) — A purification ritual particularly significant here given Izanagi’s association with cleansing; participants walk through a large reed ring to symbolically wash away half a year’s impurities.

Late April, during the Reitaisai festival, when the camphor tree’s new leaves create a canopy of fresh green and the shrine hosts its most elaborate rituals. Alternatively, visit at sunrise in late November, when morning light strikes the main hall at a precise angle that aligns with the shrine’s east-west axis — a phenomenon that some interpret as evidence of deliberate solar orientation in the shrine’s original positioning. The grounds are never crowded; even during festivals, the shrine maintains an atmosphere of quiet that feels less like absence and more like aftermath.
