Matsukawa Basalt, a hidden gem in Hachimantai City, boasts a rare feature that can hardly be found elsewhere in Japan: hexagonal rock formations. These cliffs, which resemble crystals, are especially stunning during the autumn foliage season, when they are set against the blueish streams. They are truly a masterpiece created by nature! Come and enjoy a special experience that can only be found on the Lava Flow Observation Trail.
