Rank-and-filer Asanoyama clinched his maiden championship on Saturday by beating ozeki Goeido with one day remaining at the Summer Grand Sumo Tournament.
In addition to the Emperor's Cup, the No. 8 maegashira Asanoyama will receive a trophy from U.S. President Donald Trump, who will attend Sunday's tournament at Ryogoku Kokugikan along with Prime Minister Shinzo Abe.
"There was a lot of pressure (to win as a maegashira), but I was still able to wrestle the way I ordinarily do the whole time. That was the big thing," Asanoyama said.
