The Japan Sumo Association will stage a three-day tournament in Las Vegas in October to help celebrate the city's 100th anniversary.
"It's a privilege to present this aspect of Japan's culture to the people of the world in Las Vegas," said JSA chairman Toshimitsu Kitanoumi on Tuesday.
"We are confident that Grand Sumo Las Vegas will meet the expectations of fans in the United States."
The tour will take place at Mandalay Bay Resort and Casino from Oct. 7-9 and will mark the first time in 20 years that Japan's 1,500-year-old sport has staged an event in the U.S.
The Las Vegas tournament will feature most of the sport's top wrestlers, including Mongolian grand champion Asashoryu.
