Some sumo competitors in Japan believe that not shaving during competitions brings them good luck. The Japan Sumo Association has recently decided that beards will no longer be allowed in the sport. (Long nails and tattoos are also prohibited).
An elder in the JSA is quoted as saying the dohyo ring is sacred and he wants people to feel good when they watch the sport, so competitors must be well groomed. Grand champion Kakuryu, who is the head of the group of wrestlers in the sport's top two tiers, said looking good is very important.
There are other strict rules about Sumo behavior. They are not allowed to wear regular clothes in public, they must wear the traditional Japanese wear. They are not allowed to drive cars. This rule was enacted after a serious car accident involving a wrestler.
