Mt. Nantai

Mount Nantai is a stratovolcano in the Nikkō National Park in Tochigi Prefecture, in central Honshū, the main island of Japan. The mountain is 2,486 metres high. A prominent landmark, it can be seen on clear days from as far as Saitama, a city 100 km away.

Alongside Mount Nikkō-Shirane, Mount Nantai is one of the newest volcanic edifices in the National Park. Scientific studies of the volcano's geological structure began in 1957 and have established that it was formed roughly 23,000 years ago and that its last eruption was 7000 years ago. The volcano was classified as active by the Japan Meteorological Agency in June 2017.
