Kumamoto Travel Guide: Sights, Food & When to Go

Kumamoto (熊本県) is a prefecture in the Kyushu region of Japan. Its capital is Kumamoto; it has a population of about 1.7 million and an area of 7,409 km². Mount Aso has one of the world's largest volcanic calderas.

Kumamoto is dominated by Mount Aso, one of the world's largest active volcanic calderas, whose vast grasslands and smoking crater draw visitors to hike, drive and soak in surrounding hot-spring towns such as Kurokawa Onsen. Kumamoto Castle, one of Japan's most impressive fortifications, suffered major damage in a 2016 earthquake and has been undergoing a long, closely watched restoration since. The prefecture is known for basashi raw horse meat and karashi renkon, spicy mustard-stuffed lotus root, alongside the beloved bear mascot Kumamon, created to promote regional tourism and now one of Japan's most recognizable characters. The Amakusa Islands to the west offer dolphin watching and a distinct Christian heritage dating back to early Portuguese missionary contact.
