Okaidan Meguri (Tour in the Pitch Dark Tunnel)
Okaidan Meguri or the “Tour in the Pitch Dark Tunnel” lies under the altar of the temple. This underground corridor runs beneath the main altar where the principal image of the Amida Nyorai Buddha is enshrined. Groping your way through this corridor in total darkness, if you touch the key set just beneath the sacred image, it is said that you can gain enlightenment and enter the Paradise of the Amida Buddha. There is not a light to be seen in the corridor, so please be careful not to lose your belongings.
