Kumamoto Prefecture sits at the volcanic heart of Kyushu, where an active crater the size of a small city meets one of Japan's most storied castles and hot spring towns that draw visitors back year after year. Known as both the "Land of Fire" for Mount Aso's restless caldera and the "Land of Water" for the crystal streams fed by volcanic springs, Kumamoto rewards those willing to look beyond Kyushu Region Guide the obvious stops on the island circuit.
