On March 15th every year, Japan has a huge festival for fertility and fruitfulness.
To celebrate the festival, a huge penis is carried (at least 6 feet long)- called Oo-Owasegata. It is a symbol of the source of life to all of nature.
Free sake is distributed and penis shaped candies, keychains, penis on a stick and other souvenirs can be found everywhere.
The look of the festival is quite amusing to outsiders, but the festival is a sacred and special day in Japan.
