April 28, 2007—Amateur sumo wrestlers try their hardest to make babies cry during the Nakizumo, or "crying sumo" competition at Sensoji Temple. With a priest taunting and tormenting the infants, the winner is the first one who cries. In the case of a tie, the louder wailer wins.
The belief in Japan is that crying is good for babies, so the ceremony is meant to bestow wishes of health.
