Irō Shrine, Shinto shrine in Shizuoka Prefecture, Japan

Irō Shrine stands near the tip of the Izu Peninsula in Minamiizu, its hall raised on posts above a sloping path against a rock face. The building has weathered vertical plank siding, a shallow gabled roof of green corrugated metal with green eave trim, a recessed porch with dark wooden doors on the left, and slatted windows with light frames on the right. A pale wooden railing runs along the path in front.

According to shrine tradition, the first hall was built in 701, initially housing a Kannon image and the Sixth Heavenly Deity; later En no Ozunu enshrined Iware no Mikoto. The shrine became the syncretic Kongōzan Irō Gongen and received two bales of rice from the Tokugawa shogunate via the Nirayama daikan. The present hall was rebuilt in 1901 after the Meiji separation of Shinto and Buddhism.

The shrine is also known as Irō Gongen and was formerly called Ihanare-no-Mikoto Shrine; its deity is now identified as Iware-no-Mikoto, though the sources note this is not certain. About 50 metres away, at the very tip of the cape, stands Kumano Shrine, dedicated to the deity of matchmaking after the legend of Oshizu, who lit fires on the cape to signal her exiled lover. The two are usually treated as one shrine.

The shrine stands on a rock face above the coast at the tip of the Izu Peninsula, reached on foot along a sloping path; the hall itself is raised on posts, with a pale wooden railing along the way. Sturdy footwear helps on the slope, and care is needed near the cliff edges, especially in strong wind or with children. About 50 m further out at the very tip of the cape stands Kumano Shrine, treated in practice as part of the same site.

The shrine hall stands on wooden posts above a rock cave, counted as one of the Seven Wonders of Izu. A legend from the Edo period tells of the mast pillars supporting it. About 50 metres away at the very tip of the cape stands Kumano Shrine, honoured for matchmaking after the story of Oshizu, who lit fires to signal her exiled lover.
