This festival holds on the first Sunday of April in Kawasaki Japan, and it dates back to 1997. Though it might seem like a comical tradition, it is a religious tradition with strong cultural roots; with the aim of creating HIV awareness, STIs awareness and celebration of fertility.
According to buzzfeed.com and Wikipedia, it’s centered around a local penis-venerating shrine once popular among prostitutes who prayed for protection from sexually transmitted diseases.
People also in want of the fruit of the womb also visit the temple to pray for a child. But why’s it called “The Festival of The Steel Phallus”?
Well, it’s all about a legend of a sharp-toothed demon that hid inside the vagina of a young woman and castrated two young men on their wedding nights Bit of a shocker. So the young woman sought help from a blacksmith, who fashioned an iron phallus to break the demon’s teeth, and that’s why it became a shrine.
But today, the festival is used to raise money for HIV research.
