Yamanakako Myojin Anzan Festival is held at Yamanaka Suwa Shrine in the Yamanaka area of Lake Yamanaka. The festival is associated with anzan, a Japanese term for prayers for safe childbirth, and is part of the shrine's annual local observance.
This is a religious and community occasion rather than a large commercial event. Visitors can use it as an opportunity to see a working shrine at an important time in the local calendar. Please be mindful of worshippers and follow any guidance at the shrine grounds.
The shrine is close to the lakeside area, so the festival can be combined with a walk around Lake Yamanaka or other plans in the village. Programme details are set by the shrine.
