Para-badminton athletes are classified into wheelchair and standing classes. The former is divided into WH1 for those with serious limb and trunk impairments and WH2 for those with minimal trunk impairments. The latter is categorized into SL for those with lower limb impairments, SU for those with upper limb impairments, and SS for those with short stature due to a genetic condition. Nagashima is a WH1 athlete. (Photo courtesy of Lixil)
