Rikako Ikee, a leukemia survivor, and the Japanese women's 4x100 medley relay team finished eighth on the final day of the Tokyo Olympic swimming on Sunday, while the men set a new national record in finishing sixth in the corresponding men's event.

Ikee, who made a remarkable recovery to be able to compete in her home Games after being diagnosed with the form of blood cancer in February 2019, made her first final in her third relay appearance at Tokyo Aquatics Centre. She hit the water third for Japan, taking the butterfly leg.
