Nakadake

Nakadake, or Nakadake (中岳), is a volcanic mountain that forms part of the Aso caldera on the island of Kyushu, Japan. It lies in Kumamoto Prefecture within Aso Kuju National Park and is one of the central peaks of the Aso volcanic complex. The summit reaches roughly 1,500 to 1,600 meters above sea level, and its crater, the Nakadake crater, is the most active vent in the Aso system.

The Nakadake crater is an active volcanic feature, frequently emitting steam and volcanic gases, with occasional ash plumes that have prompted temporary restrictions on hiking and access to nearby areas. The Aso volcanic complex has a long eruptive history, and Nakadake’s activity is monitored by the Japan Meteorological Agency (JMA) and park authorities. Historical records document activity dating back centuries, with more recent eruptions affecting local access during periods of heightened unrest.

Access and visiting: The area is part of Aso Kuju National Park. Visitors can reach viewpoints around the crater rim and Kusasenri grasslands when conditions permit; however, during periods of volcanic unrest, routes to the crater may be closed and advisories issued. Those planning a visit should check the latest alerts from the JMA and park management.

Name: The name Nakadake means “middle peak” in Japanese, reflecting its position among the caldera’s peaks.
