Sunrise at Tsurigane Cave, Just Before the Dawn

Kosode Coast, located on the northern coast of Rikuchu, is a scenic stretch where some of Japan’s oldest geological strata lie exposed to the sea. Towering sea cliffs and oddly shaped rock formations line the rugged shore, offering a dramatic glimpse into the Earth’s deep past.
Among its most notable features is Tsurigane Cave, a large sea-eroded cavern named after a bell-shaped rock that once hung from its ceiling. Though the rock is gone, the cave’s striking form remains.
Near the summer solstice, the morning sun rises directly through the back of the cave, casting a golden light through the cavern. This rare, fleeting phenomenon captivates those lucky enough to witness it.
The area also gained fame as a filming location for the NHK morning drama Amachan, making it a favorite spot for both nature lovers and fans of Japanese television.
