Kumamoto Prefecture is one of Kyushu's premier destinations for stargazing, offering a variety of breathtaking locations, from the vast highlands of Aso to the beautiful coastline of Amakusa and tranquil mountain areas with minimal light pollution. When weather conditions and the lunar cycle are favorable, visitors can enjoy the Milky Way, shooting stars, and seasonal constellations with the naked eye.
Following the Kumamoto Earthquake that occurred in Reiwa 8 (2026), recovery and reconstruction efforts are still ongoing throughout the prefecture. Some areas remain inaccessible, and certain roads may still be subject to traffic restrictions. Before traveling, please check the latest road conditions and facility information. By respecting local rules and safety guidelines, you can enjoy Kumamoto's spectacular night skies responsibly.
