Masanosuke Ono

is a Japanese freestyle wrestler who competes in the 61 kilogram class. In 2024, Ono became the World Champion, the Japan National champion and the U20 World champion.

Early life Ono was born in Shimano Prefecture, where he started wrestling at three years old. He attended Tosu Technical High School. During his teenage years, he won the Japan National tournament in different age-groups multiple times. In December 2023, he went up to 65 kilograms and earned a silver medal at the tournament, only losing in the finals to eventual Olympic champion Kotaro Kiyooka.

2024 In March, Ono made his international debut at the Yasar Dogu International, earning the championship at 61 kilograms. In April, he earned a bronze medal at the Asian Championships, up at 65 kilograms. In May, Ono became the Japanese National champion at 61 kilograms, earning the right to compete at the World Championships in October.

After making the U20 team earlier in the year, Ono became the U20 World champion at 61 kilograms in September, notably defeating Marcus Blaze in the semifinals. Outscoring his opposition 55–2, he notably defeated Olympic champion Zaur Uguev from Russia, reigning World champion Vito Arujau from the United States, and U23 World finalist Ahmet Duman from Turkey on his way to first World title.

2025 On February 26, Ono dropped down to 59.5 kilograms and defeated Olympic silver medalist Spencer Lee from the United States on points, in the main event of FloWrestling: Night in America.

Pennsylvania State University

2025–2026 After months of training in the United States with the Pennsylvania State wrestling team, it was announced on March 24 that Ono had committed to the Nittany Lions and would look to debut in folkstyle. As he had transferred from Yamanashi Gakuin University in Japan, he was granted two years of NCAA eligibility, though would go on to redshirt during the 2025–2026 season.

Ono had registered to compete at 57 kilograms for November's Bill Farrell Memorial International in the United States, though would later withdraw a few days before the event. Then, he registered at the same weight class for the Emperor's Cup in Japan, set to take place in December, though would later withdraw once again, now due to kidney issues.

2026–2027 In July 2026, Ono returned to freestyle action at the Corporate All-Japan Championships, which took place in Nagoya, Japan. He racked up four technical falls to claim the gold medal without surrendering a point. He then competed at RAF 12 in August, blanking US Open and NCAA finalist Ben Davino by a score of 4 points to none.
