Surviving his treatment, Kasuya was determined to make a comeback. In September, 2015 he ran his first race post-surgery, a 5000 m time trial. 5 months later he ran a 2:20:38 marathon in Tokyo, following up with a 2:24:20 in Nagano this spring. Over the summer he was featured in a series of insurance TV commercials detailing his inspiring story. Today in Osaka he was 4th in 2:19:50. It may not be a 2:11, but a return to sub-2:20 after nearly dying ranks Kasuya's among the best performances in the world this the year.
