3. Minamiaso: Railway Through a Volcano

The Minamiaso Railway runs inside one of the world's largest calderas of Mount Aso, an active volcano in Kumamoto Prefecture. The area along this railway line is blessed with abundant water. The railway suffered significant damage by the Kumamoto Earthquake in 2016, but in 2023 resumed full-line operations. We take a ride on the Minamiaso Railway, which links today's energy to tomorrow together with the unique people living along the line.
