2016 Cancellation Cancellation of the 2016 Osaka International resulted from the
Nippon Badminton Association (NBA) missing the application deadline set by the
Badminton World Federation (BWF). The BWF had notified the NBA in October 2014 of a deadline change from August to April, but this was reportedly overlooked by NBA staff. The NBA's application, submitted in August 2015 (four months past the revised deadline), was consequently rejected. Following the cancellation,
Kinji Zeniya, then executive director of the NBA, publicly apologized and stated the association planned to reapply the next year.
Discontinuation The discontinuation of the Osaka International, effective from 2024, was announced by the NBA on 27 October 2023. The decision followed discussions with tournament stakeholders and was communicated to
Badminton Asia and the BWF. According to the NBA, the discontinuation stemmed from a re-evaluation of its organizational structure and funding allocation. The NBA noted that the Osaka International had received higher funding compared to other tournaments. When the NBA proposed adjusting future funding to align with other events, the Osaka Prefectural Badminton Association indicated difficulty in continuing under those terms and relinquished its hosting role. ==Previous winners==
