Mayumi Narita, one of Japan’s most accomplished para swimmers and a six-time Paralympian, died Friday at the age of 55 after battling intrahepatic bile duct cancer, the Japanese Para Swimming Federation said. Born in Kawasaki, Kanagawa Prefecture, Narita became a wheelchair user in her teens due to transverse myelitis and later a traffic accident, but went on to dominate the Paralympic stage, winning 15 gold medals and 20 overall between 1996 and 2004. She was named Best Female Athlete by the International Paralympic Committee in 2005, retired after the 2008 Beijing Games, and later contributed to Tokyo’s successful bid for the 2020 Games before making a remarkable comeback to compete in Rio 2016 and Tokyo 2020 at age 51. Known for her resilience and innovation, she continued training despite pandemic restrictions and had planned to remain active in the sport at her home club, the Yokohama Sakura Swimming School.
