The White Heron Dance (Shirasagi-no-Mai) was very elegant in front of Sensoji temple in Asakusa, Tokyo on April 13, 2014. I caught them walking through Nakamise leading to Sensoji temple. This video shows the entire dance in front of the temple performed at 3:30 pm. I also saw them perform on the roof of Matsuya Dept. Store in Asakusa at 2:30 pm. The Shirasagi-no-Mai White Heron Dance is held in Asakusa on the second Sunday of April, mid-May for the Sanja Matsuri, and on Nov. 3.
The dance originated at Yasaka Shrine in Kyoto about 1,000 years ago to ward off epidemics and pray for good harvests. The local Asakusa tourist association resurrected the dance in 1968. A picture scroll showed that it was performed in 1652 at Sensoji temple.
