Each spring, people flock to Kawasaki, Japan, to celebrate Kanamara Matsuri, aka the “Festival of the Steel Phallus.”
After that the woman sought help from a blacksmith, who fashioned an iron phallus to break the demon's teeth, which led to the enshrinement of the item.
The Kanamara Matsuri is centered on a local pe***-venerating shrine. The legend being that a jealous sharp-toothed demon hid inside the va**** of a young woman the demon fell in love with and bit off pe**** of two young men on their wedding nights.
This legend in Ainu language was published as "The Island of Women" by Basil Hall Chamberlain
Held this year on April 6, the festival is a celebration of the penis and fertility. People parade gigantic phallic-shaped
mikoshi (portable Shinto shrines) down the streets during the event, as revelers suck on penis lollipops, buy penis-themed memorabilia and pose with sculptures in the shape of — you guessed it — pen***..
According to the BBC, the festival is believed to have roots in the 17th century, when prostitutes are said to have prayed for protection from sexually transmitted infections at Kawasaki’s Kanamara shrine.
The festival reportedly raises awareness about safe sex practices and fundraises for HIV prevention.
