At Anatoshi-iso, waves carved 3 arches along weak seams in tilted seabed layers about 130 million years old. The openings follow the rock’s cracks rather than forming at random.
Local fishermen guide small-boat tours along this coast. From the water, visitors may spot working fishers tending nets or gathering seaweed—and, when conditions allow, pass through an arch at Anatoshi-iso.
Kaminari-iwa, or “Thunder Rock,” gets its name from waves entering a sea cave and compressing the air inside into a thunder-like boom. The sound joined Japan’s “100 Soundscapes” in 1996.
At Goishi’s sea spout, incoming waves force seawater upward through the rocks. Catch it in the right sunlight and the spray may briefly carry a rainbow.
Chiyojima is a steep-sided rock island that people cannot climb—and a nesting place for umineko, or black-tailed gulls. In early summer, chicks can be seen among the rocks.
Wave-polished black pebbles on Goishihama resemble the stones used in go, giving the coast its name. Local tradition adds that these go-stone lookalikes were once presented to the lords of the Date domain.
The pines along the coastal trail are more than scenery: they were planted centuries ago, during the Edo period, as a windbreak. Today’s walk passes through a landscape shaped by both nature and local hands.
The folded strata at Anatoshi-iso, black shale at Goishihama and hornfels at nearby Tarumizu are more than dramatic scenery: Japan Heritage identifies them as traces of the mountain-building linked to Michinoku’s gold.
Near Chiyojima, a small pavilion was built using traditional Kesen carpenter techniques—with not a single nail. Inside is a hand-carved sea deity, a local craft detail tucked beside the trail.
The coast’s go-stone name lives on in local culture: a community group began its annual Goishi Coast Go Festival in 2014, and Ofunato designated May 14 as “Goishi Day” in 2016.
Goishi’s plants reflect the meeting of warm and cold currents: coastal flowers such as hamagiku and rock sedum grow in the same area as woodland plants including lilies and chiloyuri.
At nearby Ohama, a small cave comes with a local monster story: tradition says an oni, a legendary ogre, scraped it out of the rock. The tale is folklore, not a geological explanation.
Akadokura was once known for beach stones in 5 colors, which people regarded as curiosities. Nearby Kinchaku Rock has another name too: Eboshi, after the shape of a traditional cap.
Goishi Coast became both a national Place of Scenic Beauty and a Natural Monument on June 15, 1937. Its official record highlights the striking relationship between rock cracks, faults and wave erosion.
The white lighthouse at Goishimisaki is only 10.5 meters tall and first lit in 1958. It serves as a navigation mark for vessels along the indented coast and into Ofunato Bay.
