More ways to explore the area's outdoor wonders
A low, rumbling breath runs through the caldera as visitors round the rim of Aso — steam plumes from Nakadake announce a living mountain. The route moves from that raw volcanic edge into Kusasenri’s wide green sweep, where rain-formed pools reflect sky and horses graze without hurry. The day closes in Kurokawa Onsen, where river steam rises between dark-wood ryokan and narrow stone bridges.
