Every year in Japan the Hounen Matsuri festival is celebrated on March 15. It is a harvest and fertility festival where all manners of phallic symbols are used in the celebrations. Penis-shaped candies, ice cream, snacks, souvenirs, masks and pretty much any object that can be made in the shape of a dick are sold to the delight of tourists and locals.
The highlight of the festivities is the Kanamara Matsuri (“phallic parade”), in which a gigantic wooden phallus is carried from one shrine to another.
