The world number one men's badminton player shares with us the area of his game he's working hardest on, in preparation for his first Olympics... at the Games in Tokyo. Japan's home favourite found a way to have fun while pushing himself in practice during his long spell without competitions due to coronavirus cancellations and a rehabilitation period following surgery to recover from a tragic car crash at the start of 2020. He also tells us why he hasn't felt demotivated in his career, despite never being satisfied with his performance, even when winning the world title in 2019.
