In October, I visited the island of Kyushu for the first time on a family trip. Specifically, we went to Kumamoto City in Kumamoto prefecture. I’ll write about the city another time, but here, I like to write about our day trip to Mount Aso.
Mount Aso is a volcano with 5 peaks and is famous for, according to a tourist website, its “ancient caldera [which] ranks among the world’s largest, with a diameter of up to 25 kilometers and a circumference of over 100 kilometers.” At the Aso volcano museum, I learned that a caldera is land that gets pushed down like a sinkhole when a volcano erupts, forming a sort of bowl shape in the landscape, with the volcano in the middle.
As you might recall, Kumamoto suffered multiple large earthquakes in April 2016. The recovery is ongoing, and several of the train and bus lines are still disrupted. To get to the mountains, we took a bus ride of 90ish minutes from Kumamoto City to Aso City station, and from there, a special mountain bus for another 30 minutes to the Mount Aso visitor centre and museum. The ropeway line that allows you to see the main active volcano crater was closed after an eruption in October 2016. It reopened in March 2018 (well after our trip), but of course it is occasionally closed for safety reasons depending on volcanic activity.
Although we couldn’t see the smoke-spewing crater up-close, we had a fantastic hike up one of the peaks. Rather than the type of switchback trails that I’m more used to, we climbed stairs pretty much straight up the side of the peak. From the top, we had an excellent view of the caldera, the other peaks, and the active crater.
Overall, it’s a very beautiful area, and much less-visited (that is to say, not overrun with tourists) than the main hotpots of Tokyo and Kyoto. Kumamoto City is a two-hour flight or six-hour (comfy!) Shinkansen ride from the Tokyo area, and is absolutely worth a visit. The area is still suffering from the earthquakes and resultant loss of income, so visitors are most welcome.
