The jagged coastline was created by lava from the Mount Omuro eruption flowing into the sea, cooling rapidly to form prismatic jointing.
The Kadowaki Suspension Bridge, first built in 1968, sits 23 meters above the surging ocean waves.
The site hosts a unique marine ecosystem due to the dramatic depth changes and volcanic rock formations along the shoreline.
The lighthouse is one of the few in the region that allows visitors to ascend to an observation deck for 360-degree views.
During the spring, the area is known for patches of blooming hydrangeas and other coastal wildflowers along the nature trail.
The Jogasaki Coast is a 9-kilometer stretch of rugged, volcanic coastline on the Izu Peninsula formed by the eruption of Mount Omuro approximately 4,000 years ago. The area is defined by sheer, jagged cliffs composed of hardened andesite lava flows that descend directly into the Pacific Ocean. A primary feature is the Kadowaki Suspension Bridge, a 48-meter-long steel structure spanning a deep chasm between two cliff faces. Adjacent to the bridge stands the Kadowaki Lighthouse, which provides elevated panoramic views of the coastline and Oshima Island on clear days. A well-maintained hiking trail, the Jogasaki Nature Trail, follows the clifftop perimeter, connecting various scenic observation points. The landscape is characterized by diverse coastal flora, including sea cliffs with hardy, wind-swept pine trees. The interplay between the dark volcanic rock and the blue ocean is the area's geological signature.

Wear sturdy, closed-toe walking shoes as the volcanic rock trail can be uneven and sharp.
Visit on a clear, sunny day to see the silhouette of Izu Oshima island across the water.
Carry plenty of water, as there are limited facilities once you are on the coastal trail segments.
Do not attempt to scramble down the steep, unmaintained rock faces to reach the water level, as it is dangerous and prone to rockfall.
Stay on marked trails to avoid the precarious edges of the unguarded volcanic cliffs.
