Hana-no-Iwaya Shrine

Hana-no-Iwaya Shrine, located in Kumano City, Mie Prefecture, is said to be one of Japan oldest shrines. Dedicated to Izanami-no-Mikoto, the mother goddess of Japanese mythology, its defining feature is that it has no main hall. Worshipping a giant rock about 45 meters high as its sacred body, it is a power spot where the primeval faith of nature worship survives intact. It is also included among the components of the World Heritage Site Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.

Highlights

• The Giant Sacred Rock: The sight of a rock about 45 meters high towering above is breathtaking. Facing it is a roughly 18-meter rock said to enshrine the fire deity Kagutsuchi-no-Mikoto, and the prayer to nature itself, with no main hall, lets you feel the primeval mystery firsthand.
• Otsunakake Rite: A spirited rite held twice a year, in which a great rope about 170 meters long is strung from the top of the sacred rock across the grounds. Seven ropes are bundled and seasonal flowers hung from them, a rare event even in Japan.
• Nature of Kumano and World Heritage: Close to the Kumano Sea, the surrounding area spreads into the World Heritage zone of the Kumano Kodo. Hana-no-Iwaya Shrine was also registered as part of the World Heritage Site in 2004.

Enjoying the Seasons

You can worship year-round, but the Otsunakake rite held typically on February 2 and October 2 is especially worth seeing. During the mild weather of spring and autumn, worship combined with a walk along the Kumano Kodo is recommended. Being near the sea, you can worship in refreshing air on sunny days.

A Quick Tip

The form of nature worship with no main hall is a mystical experience you cannot find at other shrines. It is a spot many visit along with a pilgrimage of the World Heritage Kumano area. Timing your visit to the Otsunakake rite lets you touch the faith of Hana-no-Iwaya more deeply. When looking up at the great rock, mind your footing as well, and quietly join your hands in prayer.
