The Irozaki Lighthouse is one of the oldest in Japan, originally constructed by British engineer Richard Henry Brunton.
The Iro-jinja Shrine is dedicated to the sea deity and is uniquely built directly into the cliff face.
The cape marks the geographic boundary where the warm Kuroshio Current influences the local marine ecosystem.
The surrounding rocky coast is a designated site for viewing rare coastal plant species adapted to high salinity.
Visibility from the cape on clear days often includes the Izu Islands, including Oshima and Toshima.
Cape Irozaki is the southernmost point of the Izu Peninsula in Shizuoka Prefecture. The site features the Irozaki Lighthouse, first established in 1871 and currently an active navigational aid. Perched precariously on the cliff edge is the Iro-jinja Shrine, which appears to be suspended over the Pacific Ocean. A walking path connects the parking area to the shrine and lighthouse, traversing jagged volcanic rock formations. The headland overlooks the convergence of the Pacific Ocean and Sagami Bay, often resulting in turbulent waters. Geologically, the area is defined by Neogene volcanic rocks, including layers of tuff and scoria. The cape is part of the Fuji-Hakone-Izu National Park.
The viewing platform near the Iro-jinja Shrine provides the best angle of the shrine suspended over the sea.
Wear sturdy walking shoes with good grip as the paths involve uneven volcanic stone and slopes.
Wind speeds can be intense at the cliff edge; bring a windbreaker even in mild seasons.
Carry a hat or sunglasses, as there is minimal shade on the exposed headland.
Do not attempt to climb off the designated paths onto the cliff rocks, as the terrain is unstable and dangerous.
Maintain a quiet demeanor at the shrine area as it is a place of active worship.
