Masayuki Onodera

Career Early career Onodera attended Kodaira Daini Junior High School and Saitama Sakae High School. He won three bronze medals with the Japanese mixed team: at the 2015 Asian Junior Championships, and at both the 2016 World and Asian Junior Championships. In 2016, partnering with Hiroki Okamura in boys' doubles, he won titles at the Dutch Juniors and the India Junior International. The pair also finished as runners-up at the German Junior. That same year, Onodera was the runner-up in both singles and doubles at the 2016 National High School Championships (Inter-High).

After high school, Onodera attended Waseda University, majoring in sport sciences and competing for its badminton team. He enrolled with the goal of obtaining a teaching license, inspired by his parents who were teachers. As a freshman in 2017, he helped the Waseda team win the All Japan Student Championships (Inter-Collegiate), the university's first national team title in 24 years. The following year, he was part of the team's successful title defense and also won the men's doubles title with partner Takuma Obayashi. Onodera graduated from Waseda University in March 2021. From 2017 to 2022, he partnered with Hiroki Okamura. The duo won their first senior international title at the 2018 Sydney International and were runners-up at the 2019 Canada Open Super 100, where they were defeated by Mathias Boe and Mads Conrad-Petersen. During the Korea Masters, they notably defeated the reigning All England Open Champions, Bagas Maulana and Muhammad Shohibul Fikri. The pair also competed in the 2021 and 2022 World Championships, reaching the second round in both editions.

In 2023, Onodera formed a new partnership with Takuto Inoue, winning the Malaysia International and securing a third-place finish at the All Japan Championships.
