Who should base here
Stay inside the caldera to ride the rim roads and the climb to Kusasenri early, before the tour buses, with a public bath by the station at the end of the day.
The Aso caldera runs about 18 km east to west and 25 km north to south, with an outer rim about 128 km round, and some 40,000 people farm and live on its floor. Aso City lies in the northern half, with JR Aso Station on the Hohi line at the foot of the road up to Kusasenri and the crater.
JMA lowered Aso to volcanic alert level 2 on 1 September 2026 after a spell at level 3, and the ground within about 1 km of the Nakadake first crater is closed. The road to Aso Sanjo Plaza and Kusasenri is open. Daikanbo, on the northern rim, looks across the whole caldera to the five peaks.
The July 2026 earthquake left Aso City with light damage, and its roads, baths and restaurants run as usual. Finish a ride at Yume no Yu by the station, or eat dago-jiru at Aosora Shokudo in Ichinomiya.
