Sanriku Coast and Goishi Beach — Dramatic Cliffs and Strange Rocks

The southern Sanriku Coast of Iwate Prefecture presents a different face from its northern counterpart — wilder, more exposed, with bold headlands and volcanic rock formations sculpted by centuries of Pacific waves into shapes of extraordinary strangeness and power. Goishi Coast (Goishi-kaigan) near Ofunato city is the most dramatic expression of this landscape: a 4-kilometer stretch of wave-carved basalt that includes sea caves, arches, blowholes, and rocks worn into the perfect circular shapes that give the coast its name — "go" stones from the ancient board game.

Highlights

The signature feature of Goishi Coast is the natural "go stones" — basalt pebbles and small boulders perfectly rounded and smoothed by coastal erosion into shapes identical to the pieces used in the Go board game. These collect in crevices and hollows in the rock, creating an uncanny natural mosaic. The larger formations along the coast include the dramatic Shiodome-iwa (Tide-catch Rock), a massive boulder riddled with sea caves and passages.

A walking path runs the full length of Goishi Coast above the cliff line, offering constant drama and changing perspectives as the sea churns below. The path leads to a lighthouse at the cape end. Seasonal fishing boats and the occasional whale or dolphin passing offshore add life to the scene.

Nearby Kesennuma, a fishing city rebuilding vigorously after the 2011 tsunami, offers excellent fresh seafood and the shark-fin processing that has made it nationally famous.

Getting There & Tips

Goishi Coast is accessible from Ofunato Station on the BRT (Bus Rapid Transit) replacing the former Ofunato Line. From the stop, the coast is a short walk. Check local bus schedules as service is limited.

Best Time to Visit

Spring through autumn for coastal walking. Stormy weather in autumn and winter produces dramatic wave action but walking conditions deteriorate. Clear summer days offer the most pleasant visit.
