Sumo wrestlers make babies cry for good luck.
While most parents do everything they can to keep their children from crying, this isn't always the case in Japan. That's because it's a 400-year-old Japanese belief that if a sumo wrestler can make your baby cry, he or she will live a long and healthy life. Parents hand over their infants to sumo wrestlers during a special ceremony, who bounce their precious tots up and down and sometimes even roar in their faces to get the tears flowing. "He's not a crying baby," Mae Shige said at a 2014 event, "but today he cried a lot for us and we are very happy about it."
