A tragic incident occurred during Japan's 500-year-old 'Naked Festival' in Okayama, where three participants became unconscious and had to be hospitalized. This festival, known as the 'Saidai-ji Eyo Matsuri,' features thousands of men who gather at a temple wearing only traditional loincloths for purification rituals. Participants underwent cleansing in ice water before engaging in fierce clashes to claim sacred wooden charms, believed to bring good fortune for the year. The festival, designated as an Important Intangible Folk Cultural Asset in Japan since 2016, had regained momentum after a four-year hiatus due to the COVID-19 pandemic and was in its third year of resumption.
