Mount Koshiki

Mount Koshiki is a volcanic summit in the Ebino region rising to 1,301 meters with a distinctive crater roughly 500 meters across. The crater floor holds an emerald green marsh that stands out sharply from the surrounding landscape.

The mountain was formed through multiple volcanic activities spanning thousands of years and contributed to the development of the Kirishima mountain range. These geological processes shaped not only the mountain's form but also created the unique conditions found within the crater today.

The mountain's name comes from its crater shape, which resembles a traditional Japanese steaming pot used in local cooking for centuries. Visitors can appreciate this connection when walking around the crater rim and viewing its distinctive form from different angles.

The hiking trail starts from the Ebino Eco-Museum Center and forms a circuit of roughly 14 kilometers taking about six hours through varied terrain. Visitors should wear sturdy footwear and weatherproof clothing, as conditions at altitude can change quickly.

The crater marsh hosts rare carnivorous sundew plants and large Siberian hawker dragonflies that form a specialized ecosystem at this altitude. This habitat is so distinctive that naturalists visit regularly to study the unusual plant life and insect populations.
