Kumamoto to Mount Aso in a Single Day Without Getting Lost! The Ultimate JR & Mountaintop Loop Bus Guide + Volcanic Eruption Prep Tips.

The absolute highlight of a Kumamoto trip is a Mount Aso day tour! Don't let complicated transport stress you out. Start early by taking the JR Hohi Main Line from Kumamoto Station to Aso Station. Hop on the "Aso Mountaintop Loop Bus" right in front of the station to comfortably explore the summit's main attractions, including the Nakadake Crater and Kusasenri. The buses don't run very frequently, so checking the schedule in advance is key to a smooth trip. The most crucial step is checking the "volcanic activity"! Be sure to check the volcanic alert level on the Aso City website or the station information board the day before and the morning of your trip. Don't be too disappointed if crater access is restricted due to a raised alert level. You can still enjoy horseback riding or taking a stroll through the lush green pastures of Kusasenri, or experience the breath of the earth at the nearby Aso Volcano Museum. If there are restrictions, summit-bound buses might run on a reduced schedule or take detours, so be smart and ask the station staff for alternative routes. Thorough preparation is the real secret to fully soaking in the breathtakingly majestic views of Aso.
