How could we have missed this? March 01 is Penis Day in Japan. The actual festival is called Honen Matsuri. Celebrated every March 01 in Komaki, a town about 45 minutes north of Nagoya , Japan , this is the time of year where folks haul out a large wooden penis to give three cheers to fertility and renewal. The custom is an old one that is connected to bringing about a good harvest and having babies.
