From Wikipedia :
Hōnen Matsuri (Harvest Festival) is a fertility festival celebrated every year on March 15 in Japan. Hōnen means prosperous year in Japanese, implying a rich harvest, while a matsuri is a festival. The Hōnen festival and ceremony celebrate the blessings of a bountiful harvest and all manner of prosperity and fertility.
The best known of these festivals takes place in the town of Komaki, just north of Nagoya City. The festival's main features are Shinto priests playing musical instruments, a parade of ceremonially garbed participants, all-you-can-drink sake, and a 280 kg (620 pound), 2.5 meter (96 inch)-long wooden phallus. The wooden phallus is carried from a shrine called Shinmei Sha (in even-numbered years) on a large hill or from Kumano-sha Shrine (in odd-numbered years), to a shrine called Tagata Jinja.
