Konomiya Hadaka Matsuri

Festival highlights

The main highlight is the moment the naked men rush toward the Shin-Otoko when he appears, jostling to touch him and dispel their misfortune.

The sight of men gathering in the shrine grounds with Naoi sasa offered up gives a sense of the ritual’s beginning.

Water splashed from along the route rising as steam in the heat of the men is another scene emblematic of this festival.

Origins and History of Konomiya Hadaka Matsuri

Konomiya Hadaka Matsuri is said to have originated as a prayer to ward off epidemics, begun by imperial decree during the Nara period.

In the current ritual, a man called the Naoi-nin is chosen as the Shin-Otoko on the 2nd day of the lunar New Year. On the day of the festival, men in their unlucky years try to dispel their misfortune by touching him.

Rooted in an old prayer ritual, it continues as a Naoi-shinji centered on the Shin-Otoko and the naked men.
