This is What's Trending Today.

The sport of sumo wrestling started in Japan over 1,000 years ago.

But the Japanese have not had a native sumo "grand champion," known as a Yokozuna, since 1998. Sumo wrestlers known as Yokozuna compete at the sport's highest level.

That changed on Wednesday when a wrestler known as Kisenosato won his first championship at the New Year Grand Sumo Tournament.

Kisenosato is a 30-year-old whose real name is Yutaka Hagiwara. He weighs 178 kilograms and stands 1.88 meters tall.

Over the past 20 years, all the sumo grand champions have been from Mongolia, Hawaii and American Samoa.

Usually, wrestlers must win two competitions back-to-back to become Yokozunas. But Kisenosato was recognized because of his latest victory and strong performances in recent events. Three other wrestlers currently compete at the Yokozuna level.

Kisenosato said he would do his best to honor his new classification.

A 2015 survey showed that sumo wrestling is still the most popular sport in Japan. But other sports, like baseball, soccer, boxing and golf are rising in popularity.

Sumo's popularity suffered recently because of reports of scandals, including stories of young wrestlers being treated poorly by their mentors.

Kisenosato's success is big news in Japan. One Facebook user published an image showing his photograph on the front of six different newspapers.

A Twitter user said the title of Yokozuna comes with a lot of responsibility.

"I am confident he will deliver."

And that's What's Trending Today.
