Unosu Cliff, Coastal cliff formation in Tanohata, Japan
Unosu Cliff is a coastal cliff on the Pacific shore of Iwate Prefecture, in the village of Tanohata in northern Japan. It consists of five parallel rock faces that rise sharply from the sea, visible together from an observation deck to the south.
The rock walls formed over millions of years as Pacific Ocean waves eroded the coastline of northern Honshu. The movement of tectonic plates beneath the seabed contributed to the parallel arrangement of the faces that can be seen today.
The name Unosu means "cormorant nest" in Japanese, which reflects how closely the local identity of this place is tied to its seabirds. Visitors today can often spot cormorants perched on the ledges or flying low over the water below.
The observation deck south of the cliffs is the best spot to take in all five rock faces at once, and it is reachable on foot. The ground around the overlook is uneven and the wind can be strong, so sturdy shoes are a good idea.
Eagles and ospreys also nest in the same rock faces as the cormorants, making this one of the few spots on the Iwate coast where several bird species share a single cliff wall. Coming in the early morning gives the best chance of seeing them in flight.
