The Japan Sumo Association has reprimanded yokozuna grand champion Hakuho for leading an unapproved cheer during his victory interview last month.
Hakuho's action came as he was being interviewed near the ring as the winner of the Spring Grand Sumo Tournament. He led an impromptu "sanbon-jime" hand-clapping cheer.
Sumo grand champion Hakuho notched an unprecedented 1,000th victory in the sport's top division on his way to claiming his record 41st Emperor's Cup at the autumn tournament on Saturday.
The Mongolian yokozuna finished the previous day with a record of 13 wins and no losses, followed by ozeki champions Takayasu and Goeido with 11 wins and 2 losses.
