Unosu Cliff

Unosu Cliff is a coastal rock formation on the northern coast of Iwate Prefecture where five parallel cliff faces rise sharply from the sea. These formations extend approximately 200 meters high and together create a dramatic natural landscape along the Pacific shoreline.

The cliff formation developed over millions of years through oceanic erosion and Pacific plate tectonic movements that continuously shaped the rock. This geological process created the parallel structures visible today.

Local fishermen have recognized these rock walls as natural landmarks for generations when navigating these waters. The cliffs also provide nesting habitat for various seabirds that make their homes in the crevices and ledges.

An observation deck located south of the cliffs provides clear views of all five rock formations year-round. Visitors should wear sturdy footwear and be prepared for uneven terrain, as the area around the overlook is hilly and often windy.

The name comes from cormorants that build nests in the cliff crevices and define this special place. Eagles and ospreys also inhabit the cliffs, sharing this rocky habitat with the nesting seabirds.
