A large bronze bell on the portico of Zenko-ji Temple in Nagano Japan. Nagano's Zenkoji Temple (善光寺, Zenkōji) is one of the most important and popular temples in Japan. It was founded in the 7th century and stores the first Buddhist statue ever to be brought into Japan when Buddhism was first introduced in the 6th century. The original statue is hidden while a copy of it is shown to the public every six years for a few weeks. The next opportunity will be in 2021.
In the basement of the inner chamber is an underground passage, which visitors walk through in complete darkness in search of the "key to paradise". The key is attached to a wall along the corridor and is believed to grant salvation to anybody who touches it.
