Overview
The Naked Festival, known as "Hadaka Matsuri" in Japanese, is a collective term for traditional Shinto rituals held across Japan. These festivals are characterized by men wearing only loincloths (fundoshi) gathering in the cold of winter or at night to perform sacred acts. Many of these festivals are designated as Important Intangible Folk Cultural Properties of Japan or as cultural properties by local municipalities, serving as precious traditions that convey regional history and faith to the present day. Representative examples include the Saidaiji Eyo in Okayama City, Okayama Prefecture, the Konomiya Hadaka Matsuri (Naoi Shrine Ritual) in Inazawa City, Aichi Prefecture, and the Futamata Tenjin Hadaka Matsuri in Iwata City, Shizuoka Prefecture.
The Naked Festival is not merely a peculiar spectacle but a solemn religious event praying for abundant harvests, good health, and the warding off of evil. Participants purify themselves in the severe cold and approach the sacred space, embodying spiritual purification and rebirth. In particular, the act of serving before the gods in a naked state has been considered an important ritual since ancient times, representing a return to one's original human form and a direct encounter with the divine.
History and Origins
The origins of the Naked Festival vary by region, but many trace their roots to Buddhist or Shinto rituals from the Muromachi period to the Edo period. According to the temple tradition of the Saidaiji Eyo, it began during the Eisho era (1504-1521) of the Muromachi period when the priest Chua Shonin gave protective amulets to worshippers. As the number of applicants increased, in 1510 (Eisho 7), he threw paper protective amulets called "go-o" over the heads of the gathered crowd, and the scramble to catch them is said to be the origin of the Eyo. This suggests that the act of scrambling for amulets reflects the earnest desire of people seeking divine protection.
Initially, participants wore clothing while scrambling for the amulets, but it is speculated that they gradually shed their clothes for greater ease of movement. A picture scroll bearing the date 1661 (Kanbun 1) depicts the early state of the Eyo, showing both naked and clothed people intermingled. This indicates that the practice of participating naked gradually became established over time. The act of being naked developed as an element that strengthened the religious significance of the festival.
The Konomiya Hadaka Matsuri (Naoi Shinto Ritual) is said to have originated about 1,250 years ago when the governor of Owari Province performed a purification ritual at Owari Okunitama Shrine, the general shrine of Owari Province. This ritual was originally a purification ceremony held in the spring season, aimed at dispelling evil forces with sacred power. The combination of this ritual with the custom of cold-weather pilgrimage in the nude is believed to have resulted in the current festival during the late Edo period.
The Futamata Tenjin Hadaka Matsuri in Shizuoka Prefecture is a ritual held at Yanahebi Jinja Shrine and is designated as a National Important Intangible Folk Cultural Property. This festival has the character of a Shinko-sai (a festival where the deity travels through the parish area), which occurs only once a year, and participants serve the portable shrine and sacred objects in the nude. While the exact origin of the festival is not clearly documented, it has been positioned as the center of regional faith as a traditional event that has continued since ancient times.
Highlights
Distribution of the Dedicated Giant Rice Cake At the Konomiya Hadaka Matsuri, the "Giant Rice Cake" (Omochi) dedicated by neighborhoods in the Owari area is a major highlight. Its size is approximately 4 tons (equivalent to 50 bales of rice), and it is transported to the shrine from the dedicated area the day before the main festival. This rice cake is cut and distributed to worshippers at the Naoi-den Hall from around 8:00 AM on the 14th day of the old lunar calendar, the day after the main ritual. It is believed that eating this rice cake brings protection from illness and disaster, and many worshippers visit to obtain it.
The "Naoi-bito" in Loincloth The central participants of the Konomiya Hadaka Matsuri are the "Naoi-bito" (purification people), mainly men who are 25 years old, the traditional age of misfortune. They wear only a white loincloth and white tabi socks, gathering in the severely cold precincts. The sight of several thousand naked men from throughout the Owari region moving dynamically in the sacred space is overwhelming. This appearance symbolizes the essence of the festival: confronting the gods in one's natural human form.
Throwing of the "Shingi" Sacred Sticks At the Anyoji Eyo in Mimasaka City, Okayama Prefecture, the climax involves a performance where bundles of protective talismans called "Shingi" are thrown into the darkness. At 9:05 PM, the secondary Shingi is thrown at the sound of the second drum, followed by the main Shingi at the sound of the third drum, which is thrown into the crowd. At this moment, the lights are turned off, and in the pitch darkness, participants become enveloped in heat and excitement as they scramble for the talismans. The precincts, heated by the fervor of the scramble, represent the true essence of this traditional peculiar festival.
The Sacred Running of the "Kagura" Movements At the Kumano Shrine Naked Festival in Tamba City, Hyogo Prefecture, participants run back and forth seven and a half times between the main hall and the dance hall, shouting "Yoi-sa, Oi-sa" in the nude. Subsequently, they circle the dance hall three times in pursuit of the return of sacred treasures, followed by a scramble for sacred wands (Gohei). These movements are said to contain traces of divine possession, and the participants' jumping postures are filled with sacred dynamism. Since this festival was already mentioned in the local gazetteer "Tamba-shi" from the Edo period, it is known to have been performed at least from the early modern period.
The Deep Sound of Drums and the Customs of the Dark Night At the Futamata Tenjin Hadaka Matsuri, the "Oni Odori" (demon dance) and the procession of the portable shrine in the darkness of the night create a unique atmosphere. The festival proceeds with the deity appearing at midnight on Saturday, transferring to the Taniumi Kunitama Shrine, then touring the parish area on Sunday, and returning to Yanahebi Jinja Shrine at night. In this festival, both participants and spectators are required to observe the "customs of the dark night," maintaining the dignity of the sacred night event. The preservation society is working to ensure that all members follow the safety manual to pass on this tradition to the future.
Simultaneous Holding of Children's and Adults' Eyo A distinctive feature of the Anyoji Eyo is that the adults' Eyo and the children's Eyo are held separately. The participation of children plays an important role in passing on the tradition to the next generation, providing an opportunity to experience the spirit of the festival from a young age. Unlike the adults' Eyo, where men in loincloths scramble for talismans, the children's Eyo is conducted with greater consideration for safety and is crowded with local families. In this way, the sharing of the festival across generations strengthens community bonds.
