Walk across black earth created by Mount Iwate's eruption—a national special natural monument
About this spot
A vast lava field approximately 3km long and 1km wide, formed when lava from a Mount Iwate eruption in the Edo period cooled and solidified in place. Designated as a national special natural monument, the black rocky landscape—where barely any plants have taken root even 300 years after the eruption—completely blankets Mount Iwate's foothills in an awe-inspiring sight. Within the lava flow runs approximately 1km of natural observation paths. As you walk over the rough terrain, Mount Iwate looms majestically behind you, while ahead stretches only black earth and sky—an otherworldly experience. This encounter with the raw volcanic face of Hachimantai, contrasting with the verdant slopes, marks the highlight of the second half of your drive.
Tips
About 50 minutes by car from the Hachimantai summit; access the observation path from the Yakebashiri International Exchange Village parking area. The rocky terrain has unstable footing in places, so wear comfortable hiking shoes like sneakers. The observation path offers no shade, so bring a hat and plenty of water for safety.
Best time to visit
Approximately 1 hour. Late afternoon light is best when Mount Iwate's ridgeline becomes dramatic and photogenic
