In recent years, Shirai had struggled to produce high scores that had vaulted him to among the sport’s elite with the nagging left ankle injury.

Passing his retirement news, Kenzo shared that he has no regrets and had an incredibly blessed gymnastics career.

Similarly, Kenzo has left behind a half dozen gymnastic techniques named after him. Thus, the “Flipping Prince” has already made a name in the history of Japanese artistic Gymnastics.

But in his last game, fans in the stand roared at the sight of Shirai performing a signature backflip with four twists, a technique that he had sealed off for years due to injuries.

Coaching Career

Following his retirement, Kenzo moved straight into coaching following the national apparatus championship. Although Kenzo said it’s easy for him to get out of competitive gymnastics, he enjoys teaching other gymnastics rather than developing his skills.

Ever since he was at Nippon Sport Science University, his enthusiasm for teaching younger students increased, and he thought it was a suitable time to retire.

However, Shirai denied that the injury’s dire consequences and hardships were not the reason behind his retirement and leaving the floor forever.
