Hadaka Matsuri
A shared label. Different local observances.
Hadaka matsuri, often translated as “naked festival”, is a descriptive label used for several different Japanese festivals involving minimally clothed participants. It does not name one national ceremony with a single origin or set of rules. Many participants wear a fundoshi or other prescribed garment, and clothing is only one part of the event’s religious meaning. Saidai-ji Eyo in Okayama centres on a Buddhist observance and sacred wooden objects; Kōnomiya in Aichi centres on a shrine ritual for removing misfortune. Comparing these examples shows why place, institution and local terminology matter more than an arresting English label or a photograph of a crowd.
Institution
A particular shrine or temple.
Ritual
A locally defined purpose and sequence.
Community
Participants with different responsibilities.

01
A shared label does not create a single festival
Hadaka refers to nakedness or a state of undress, but photographs commonly show participants in prescribed loincloths. The label highlights appearance while leaving the actual ritual unexplained. The formal event name, community and sponsoring temple or shrine are more useful starting points for understanding what takes place.
02
Saidai-ji Eyo belongs to a Buddhist observance
Saidai-ji Kannon-in connects Eyo with Shushō-e, a New Year Buddhist service. Its traditional account dates the distribution of protective paper talismans to 1510 and describes growing competition to receive them. The current ritual uses sacred wooden objects called shingi. This is a temple-specific history, not an origin story for every festival called hadaka matsuri.
03
Saidai-ji and Kōnomiya centre on different acts
The two prominent examples should not be merged into a generic contest for good luck.
- Saidai-ji Eyo
- A Buddhist temple observance in Okayama, including purification and the taking of shingi.
- Kōnomiya Naoi Shinji
- A shrine observance in Aichi involving the shin-otoko and beliefs about removing misfortune.
- Local organisation
- Each institution sets its own sequence, roles and participation arrangements.
04
Kōnomiya’s central meaning extends beyond the crowd
Owari Ōkunitama Shrine gives the formal name Naoi Shinji and associates its origin tradition with prayers against epidemic disease in 767. Participants seek contact with the selected shin-otoko as an act of misfortune removal. The shrine also describes a subsequent nocturnal rite involving a clay rice-cake substitute, showing that the visible crowd scene is only part of the observance.
05
Participation includes more than one visible role
Saidai-ji’s own account records women performing Eyo drums and taking part in water purification. Kōnomiya describes votive cloth offerings carrying wishes from people beyond the main crowd. These examples complicate shorthand descriptions of an exclusively male festival, while not implying that every role is open to everyone. Eligibility and arrangements belong to the named event and year.
06
Recognition applies to a particular tradition
The Agency for Cultural Affairs documents Saidai-ji Eyo as a specific folk cultural property, including its regional relationship to other Eyo observances. That recognition is not a designation of all hadaka matsuri as one heritage element. When reading a schedule or attending as a spectator, use the institution’s current information; a dramatic historical image is neither a participation guide nor evidence that all local practices are unchanged.
