Hadaka Matsuri


A Hadaka Matsuri is a type of Japanese festival, or matsuri, in which participants usually wear a minimum amount of clothing - usually just a fundoshi loincloth, sometimes with a short happi coat - and rarely are completely naked.
Naked festivals are held in dozens of places throughout Japan every year, usually in February or November.

Hayama-gomor

Hayama-gomor at Kuronuma Shrine, district of Kanezawa, Fukushima, held for three days starting around 16 November but varying with the lunar calendar, is a secret ceremony that has taken place for over a thousand years, in which omens from the gods are bestowed on humans, that is considered off-limits to visitors, but there are no restrictions on viewing the ta-asobi portion.
For a three-day period, the men who enter the area first purify their bodies in a hall located near the shrine. At five in the morning each day, they strip naked at a sacred well and douse themselves with the freezing water as they offer prayers: their own, their friends’ and their family members'. During this period, their diet consists of locally harvested hakusai cabbage and daikon radish, along with white rice steamed in well water.
On the first night, the participants, in loincloths, perform a ritual ceremony evoking rice farming. Drums beat in a representing thunder and clouds and the participants move in procession in circles, praying for rain. Then they collide together in a mock cavalry battle while crying "Yoisa!" to represent plowing by farm horses. They then pick up and drop tatami mats evoking rice seedling planting, while singing planting songs. The ritual ceremony ends with prayers for a bountiful rice farming year.
On the second day, in the nude, they pound mochi rice into cakes to offer to the gods. In another room, elders turn vegetables into male and female forms to be offered to the gods.
On the third day, from three in the morning, yama-gake begins. Participants wear tenugui head coverings and a white costume looking like ritual dolls, then ascend the mountain. They then stand in front of a shrine and listen to a bell rung to purify their hearts. A noriwara is then possessed by the gods and foretells the weather and the coming harvest.
This ceremony is the origin of the hadaka-matsuri, in which participants purify their bodies in preparation for contact with the gods.

Konomiya

One of the biggest and oldest Hadaka Matsuris is the Owari Ōkunitama Shrine Hadaka Matsuri held in Inazawa, where the festival originated over 1300 years ago. Every year, people participate in this festival in hopes of gaining luck for the entire year. The most famous part of the festival is when the shin-otoko enters the stage and has to find a way back to the shrine, called naoiden. The participatants must try and touch the shin-otoko to transfer their bad luck. During the nighttime ceremony, all the bad luck is transferred in a charcoal colored giant mochi. The black mochi is made with rice mixed with the ashes of the burned omamori from last year. The mochi is then buried in a secret location in the nearby forest.
Women took part in the festival for the first time on 22 February 2024, with a group of 41 clothed women having a minor role.
