The 2'486 metres high Nantai-san, also known as Futarasan, is a volcano within the Nikko National Park in central Honshu (Tochigi Prefecture). It is a prominent landmark and can be seen in a clear day even from the Pacific coast. Mount Nantai is one of the 100 famous mountains in Japan.
The Futarasan Chugushi Shrine is situated at the north side of Lake Chuzenji and at the foot of Mt. Nantai. The name Chugushi literally means middle shrine. It is located between Futarasan-jinja shrine on the top of the Mt. Nantai and the Main shrine in the central of the city of Nikko. This shrine was built as a place to worship Mt. Futara (actually known as Mt. Nantai) in the year 784 by the priest and Nikko founder Shodo Shonin.
