A low wind pushes across the broad grasslands and the rim opens like a page: the Aso Caldera spreads below, its inner plain and the smoking bulk of Mt. Aso drawing the eye. The walk begins at Futae Pass, where guides set the pace and point out the layered cliffs that mark the caldera’s rim. Footsteps follow an old stone-paved route, the Bungo Kaido, and the landscape feels provincial, immediate and vast.
