Kiyoharai

Shinto priests walk out from a gate after they administered a Shinto rite "Kiyoharai" on the first day of the three-day spring festival at the controversial Yasukuni shrine in Tokyo on April 21, 2015. Japanese Prime Minister Shinzo Abe made a symbolic donation to the Yasukuni war shrine, but stopped short of visiting in person -- a move that would have infuriated neighbouring countries. Abe donated a sacred "masakaki" tree to coincide with the start of the three-day spring festival at the shrine in central Tokyo
