Okayama's Naked Festival
Every year in Okayama, Japan, nearly 10,000 men take part in the Hadaka Matsuri, or Naked Festival at Saidaiji Temple.
The men, dressed in Japanese loincloths, battle to grab a pair of lucky talismans thrown into the crowd by priests. Participants in the boisterous event are asked to prepare papers with their name, blood type and emergency contact number, and tuck them into their loincloths beforehand. The recipients of the talismans are believed to enjoy luck the following year.
