Onosato Daiki 大の里 泰輝 — 第75代横綱

Onosato Daiki (大の里 泰輝) — born Daiki Nakamura on June 7, 2000, in Tsubata, Ishikawa Prefecture — is the 75th Yokozuna in the history of professional sumo and the sport's most dominant active force. He rose to sumo's highest rank in May 2025 after just 13 professional tournaments, the fastest promotion in modern history by a significant margin.

His achievement carries profound cultural weight in Japan: Onosato is the first Japanese-born Yokozuna since Kisenosato in 2017 — after Kisenosato retired in January 2019, every yokozuna until Onosato had been Mongolian-born. In a sport deeply tied to Japanese national identity, his emergence has been met with the kind of public excitement not seen since Kisenosato's own promotion.

At 190cm and 188kg (JSA official profile), Onosato combines the physical attributes of sumo's elite heavyweights with a speed and technical precision that is genuinely unusual for his size class. He trains at Nishonoseki Stable under the guidance of his stable master — former Yokozuna Kisenosato, himself the last Japanese-born grand champion before Onosato — creating a rare continuity of Japanese yokozuna mentorship.

Onosato began wrestling at age 7 at the Tsubata Junior Sumo Club (津幡町少年相撲教室) in Ishikawa Prefecture. He developed steadily through his youth, but his truly exceptional talent revealed itself at Nippon Sport Science University (日本体育大学, "Nittai"), one of Japan's premier sumo programs.

During his four undergraduate years, Onosato won an extraordinary 13 amateur titles — tying the record for the most amateur titles (Wikipedia). As a freshman in November 2019 he won the national student championship (学生横綱), and he became Amateur Yokozuna (アマチュア横綱, All-Japan Sumo Championships) in December 2021 and again in 2022. He also won the National Sports Festival (国体) individual title in 2019 and 2022, and the open-weight gold at the 2022 World Games.

His amateur record set expectations almost impossibly high — and he has exceeded them.

Amateur highlights

• Started wrestling age 7 — Tsubata Junior Sumo Club, Ishikawa
• Nippon Sport Science University (日体大)
• 13 amateur championship titles — tied all-time record
• 2× consecutive Amateur Yokozuna (アマチュア横綱, 2021 & 2022)
• Student Yokozuna (全国学生相撲選手権) as a freshman, 2019
• Kokutai Tournament winner × 1st year
• Debuted professional as Makushita 10 tsukedashi (special entry) due to amateur achievements

Onosato turned professional at the May 2023 Natsu Basho, entering via the makushita tsukedashi system at Makushita 10 — a special privilege granted to wrestlers with exceptional amateur records. From his very first tournament, the trajectory was extraordinary.

He reached the top Makuuchi division in January 2024, his 5th professional tournament. In May 2024 — his 7th tournament — he won his first top-division championship as a Komusubi (12–3), the fastest debut-to-first-title on record (the previous best for a makushita tsukedashi entrant was Wajima's 15 tournaments). After a second title as Sekiwake in September 2024 (13–2) he was promoted to Ozeki after just 9 tournaments, the fastest since the Showa era began.

The Yokozuna promotion came in May 2025. After winning back-to-back championships at Ozeki, the Yokozuna Deliberation Council unanimously recommended his elevation to the 75th Yokozuna. He had appeared in just 13 professional tournaments — the fastest since the six-tournament year began in 1958, beating Wajima's 21. He did not post a single losing record on the way.

In 2025, he won 3 yusho and accumulated 71 wins for the year (71–19), the most of any wrestler that year (年間最多勝).

Belt wrestling first (yotsu-zumo)

Onosato's primary approach is yotsu-zumo — belt wrestling. He seeks a right-hand inside grip (右四つ) on his opponent's mawashi early in the bout, then drives forward with overwhelming force. His most common winning technique is yorikiri (force-out), which accounts for a significant proportion of his victories. Once he establishes his preferred grip, very few wrestlers can resist the combination of his weight, leg drive, and balance.

Oshi threat keeps opponents honest

What prevents opponents from simply blocking his belt attempts is his credible oshi-zumo game — powerful thrusting and pushing attacks that he deploys when the belt is not immediately available. This dual threat makes his offensive approach exceptionally difficult to defend: if you brace for thrusts, he goes to the belt; if you give him the belt, he drives you out.

Size with unusual athleticism

At 190cm and 188kg, Onosato is among the larger wrestlers in the top division. The Japan Sumo Association lists his specialties as tsuki, oshi, migi-yotsu, yori (突き・押し・右四つ・寄り) — thrusting and pushing, plus a right-hand-inside belt grip and force-outs.

Onosato trains at Nishonoseki Stable (二所ノ関部屋), one of professional sumo's most historically prominent stables. His stable master is the former Yokozuna Kisenosato (稀勢の里, the 72nd Yokozuna), who retired in 2019 after a career defined by both triumph and persistent injury.

The mentor-student relationship carries significant symbolic weight. Kisenosato was himself the last Japanese-born Yokozuna before Onosato — a wrestler who became a national hero by ending a long drought of Japanese grand champions, only to retire early due to injury. Training the next Japanese Yokozuna represents, for Kisenosato, a form of completion.

Onosato has spoken about choosing Nishonoseki specifically because of its relative isolation from urban distractions — a deliberate choice to prioritize training environment over convenience. This level of dedication from a wrestler his age is noted by observers as one of the keys to his unusually fast development.
