According to one theory, kagura can be traced back to the Legend of Ama no Iwato, a book of Japanese myths compiled at the order of Emperor Tenmu in the 7th century. This legend inspired a ritual for the repose of souls. Held during the time of year when the sun is at its weakest, kagura is said to summon the might of the gods to bring back the sun and bring new life, and to serve as a prayer for a stronger life force in us all.

Story
Kagura stories are quite closely based on real events in history, so if you learn about those events before watching the performance, you’ll find the story even more interesting and easier to follow.
With that said, it’s also fine to just sit back and enjoy the show. When you do that, you look back and realize that that was enjoyable in itself. So don’t worry too much about what you “should” be noticing – just have fun!
There are 22 kagura troupes in Akitakata City, each affiliated with a different shrine in a different region. Each troupe leads kagura dancing at their shrine’s annual festivals, with members of the shrine’s sect dancing together.
