On Wednesday, Onosato, a 29-year-old native of Osaka, celebrated this milestone following his victories in two consecutive top-division tournaments held in Osaka and Tokyo. His promotion marks a triumphant moment for local sumo enthusiasts who have witnessed a decline in Japanese wrestlers at elite levels. With only 13 tournaments under his belt—a record-fast ascension since the current promotion system was instituted in the 1950s—Onosato has expressed determination to maintain his unique style and contribute to the legacy of the sport.

Yokozuna are selected by a council of elder judges based on their performance; once awarded the title, they can never be demoted. Currently, Onosato shares the rank with another yokozuna, Hoshoryu, who is Mongolian and earned his title earlier this year. Onosato's recent victory in the May tournament, where he secured a 14-1 record, highlighted his possible future reign in the sport, as he consistently outperformed competitors, including Hoshoryu, who finished with a 12-3 tally.

“I want to maintain my style, be Onosato, and I will work hard to become a unique and unparalleled yokozuna,” he remarked during a press conference, showcasing his dedication to elevating Japanese sumo wrestling in the coming years.
