Onosato, 24, has been promoted to yokozuna, the highest rank in sumo. In terms of speed, it was a record-breaking rise to the pinnacle of the sport, signaling the birth of a star wrestler with both popularity and ability.

Hailing from Ishikawa Prefecture, Onosato is the first Japan-born wrestler to become a yokozuna in eight years, following his mentor Kisenosato (now stablemaster Nishonoseki).

His promotion to yokozuna after just 13 tournaments since his debut is the fastest since the annual six-tournament system began in 1958, surpassing the 21 tournaments it took the champion Wajima, who was also from Ishikawa Prefecture, by a wide margin. Onosato's promotion also came after just nine tournaments following his entry into sumo's top makuuchi division, outpacing the Showa-era (1926-1989) grand yokozuna Taiho, who achieved the feat after 11 tournaments.

In this year's May Grand Sumo Tournament, where his promotion was on the line, Onosato secured his second consecutive tournament victory on the 13th day. His total of four tournament wins is the most among active wrestlers.

Onosato stands 192 centimeters tall and weighs 191 kilograms -- hefty even in the world of sumo -- and he wrestles with power from his large physique, coupled with speed at the initial charge.

The wrestler's growth on the technical side has also been remarkable. From a young age, he has been diligent in his research of the sport, frequently questioning his coaches, analyzing match videos, and polishing his techniques.

He seized the opportunity to ascend to the top of the sumo rankings in his first attempt, also demonstrating the mental strength to withstand the pressure. As his rank has increased, so has his popularity.

Onosato is the second yokozuna to come from a student sumo background, following Wajima. During his time at Nippon Sport Science University, he became a student yokozuna and an amateur yokozuna. His achievements were recognized, allowing him to debut in the makushita division, several above the lowest jonokuchi division.

The Yokozuna Deliberation Council unanimously recommended his promotion, with members successively expressing hopes that he would make new history in professional sumo.

At the ceremony in which messengers from the Japan Sumo Association officially informed Onosato of his promotion, he declared his aim to become a "unique yokozuna." If he continues to work hard, he certainly has the potential to become a grand yokozuna.

There was an incident in the past where Onosato received a stern warning from the Japan Sumo Association for drinking with a wrestler under 20. As a yokozuna, he will now be held to strict standards of "dignity."

Onosato's success is uplifting those affected by last year's Noto Peninsula earthquake in Ishikawa Prefecture. He is also driven by the support from people in his hometown.

After the first tournament of the year, Mongolian-born Hoshoryu, 26, was similarly promoted to the rank of yokozuna, and the Nagoya tournament in July will have both an east yokozuna and a west yokozuna for the first time in four years.

Amid concerns about a shortage of new wrestlers, it is hoped that they will strive through friendly rivalry to create an Onosato-Hoshoryu era and lead the sumo world.
