The naked festival, which includes an event in which men who have performed misogi (a cold-water purification ceremony) fight over the symbol of the festival (such as a sacred tree or a ball) in or outside the main hall of the shrine, is often held around midwinter time when the farmland lies idle.
裸祭は禊（水行）の後、お堂の内外で神木、玉、等、その祭の象徴を奪い合う会陽を始めとして休耕となる真冬を中心に開催されるものが多い。
