(CNN)In a blow for fans of sporting stubble, Japanese sumo officials have shown their razor sharp intent by banning wrestlers from growing beards.
A number of superstitious sumo wrestlers choose not to shave their beards during competition, believing that such a move would bring about bad luck.
But in a sweeping new move that has also outlawed tattoos and long nails, the sport's authorities have declared that any failure to adhere to the new rules will leave wrestlers a whisker away from trouble.
"Wrestlers must preserve their personal hygiene," Japan Sumo Association elder Oguruma told reporters after a board meeting.
"Officials and referees will be on the lookout. The sumo ring is sacred and it's important spectators don't see anything unsightly."
The move is seen as an attempt to clean up the sport following a series of scandals including match-fixing and violence in recent years. In October, the JSA issued a declaration pledging to eradicate violence from the sport.
