Japan competed at the 2022 BWF World Championships in Tokyo, Japan from 22 to 28 August 2022. Japan sent 32 shuttlers who will play in all five events. Japan was the only nation that put a maximum of four representatives in each event.
Japan had two defending champions: Akane Yamaguchi in women’s singles and Takuro Hoki / Yugo Kobayashi in men’s doubles.
Japan became the top nation at the previous edition of the BWF World Championships in Huelva, Spain with five medals (two golds, one silver, and two bronzes).
Despite a host, Japan had a less than successful experience at the 2020 Tokyo Olympics where they only won one medal in the badminton events. It was beyond the expectations of many because Japan had evenly distributed power in all sectors at that time, especially the men’s singles and women’s doubles.
