Kumamoto is built around one of Japan's most impressive castles, still being restored after the 2016 earthquake but no less striking for it, and serves as the main gateway to the volcanic landscapes of Mount Aso. The city's Suizenji Garden recreates famous landscapes in miniature, while a short trip out brings you to the vast caldera and grasslands of Aso, one of the world's largest active volcanoes.
