There is a lot to be seen such as a huge Torii gate, five-storey pagoda, Omote-mon, Yomei-mon, Maneki-Neko, Honden (main hall) and Haiden (Hall of Worship).
There is another shrine called Futarasan-Jinja. It was established by Shodo Shonin (Buddhist priest in 8 centuries). It's dedicated to the mountain, Nantai, the mountain's consort, Nyotai, and their mountainous progeny, Taro.
The Tendai-sect Rinno-ji was founded 1200 years ago by also Shodo Shonin. The central object of worship here is a statue of the Senju (1000-armed Kannon).
