Kumamoto Castle and Mount Aso: Rebuilding and an Active Volcano

Kumamoto Castle suffered serious damage in the 2016 Kumamoto earthquakes, and full restoration has been a multi-year project. The main keep has reopened to visitors, but some walls, turrets, and grounds may still be under repair or closed off depending on when you visit — check the current status before you go rather than assuming full access.

Mount Aso sits inside one of the largest volcanic calderas on Earth, with towns, farmland, and roads laid out across the caldera floor — it's a strange, striking landscape to drive through. It's also an active volcano, and crater-area access opens and closes based on current gas and eruption activity. Always check current advisories before planning a visit to the crater itself.

Kumamoto City is on the Kyushu Shinkansen line, making it an easy add-on from Fukuoka or Kagoshima. Mount Aso is less convenient — a car makes it far easier, though limited buses run from Kumamoto City on a fixed schedule.
