Babies face off in Japan's 'crying sumo' contest

Dozens of babies face off in a traditional "crying sumo" ring, in an annual event at a Tokyo temple believed to bring infants good health. Staff wearing "oni" demon masks tried to make the babies cry, with the first to bawl declared the winner by a sumo referee in an elaborate traditional uniform holding a wooden fan used to signal victory. 

The "crying sumo" is held at shrines and temples nationwide, to the delight of parents and onlookers. The rules vary from region to region -- in some places parents want their offspring to be the first to cry, in others the first to weep is the loser.
