“A Hadaka Matsuri (“Naked Festival”) is a type of Japanese festival, or matsuri, in which participants wear a minimum amount of clothing; usually just a Japanese loincloth (called fundoshi), sometimes with a short happi coat, and rarely completely naked. Whatever the clothing, it is considered to be above vulgar, or everyday, undergarments, and on the level of holy Japanese shrine attire. Naked festivals are held in dozens of places throughout Japan every year, usually in the summer or winter. The most famous festival is held in Okayama, where the festival originated. Every year, over 9,000 men participate in this festival”. – Wikipedia
