Goishi Coast

The Goishi coast runs about six kilometres around the end of the Massaki peninsula and is named for the beach of flat black stones that look like go pieces. It is a geosite of the Sanriku Geopark, the largest geopark in Japan, and the rock here has been worked by the Pacific into arches, blowholes and clefts.

A walking path of about seven and a half kilometres links the whole set — the pine woods above, the black stone beach, and the eight named features collectively called the Eight Views of Goishi. Anatoshi-iso is a rock with three sea arches punched through it; Kaminari-iwa booms when swell hits the cave under it; Ranboya is a narrow chasm with the sea working at the bottom. Camellias flower red along the path in early spring. It is free.
