is a Japanese professional swimmer who specializes in individual medley, butterfly, breaststroke, and freestyle events. He holds the world record in the short course 400-metre individual medley and formerly held the world record in the short course 200-metre butterfly. He won the gold medal in the 400-metre individual medley at the 2012,[3] 2014, 2016, 2018, 2021, and 2022 world short course championships, as well as at the 2013, 2015, and 2019 world long course championships.
Seto took up swimming at the age of five.[1] [4] He narrowly missed the 2012 Japan Olympic Team when he finished third in both the 200-metre and 400-metre individual medley events at the national selection meet. He improved his times at the 2012 FINA Swimming World Cup, where he competed at all stops of the World Cup circuit and achieved a fourth-place finish across all stops. He concluded the year's short course season at the 2012 World Short Course Championships. Here Seto won the first international medals of his career. He first competed in the 400-metre individual medley, where he won his first world title in a new Asian record of 3:59.12, over a second and a half faster than second-place finisher László Cseh. He then competed in the 200-metre individual medley, where he was able to sprint past Cseh for the silver medal in a time of 1:52.80.
Seto was still coming into the 2013 World Aquatics Championships in Barcelona, Spain, relatively unknown. He swam both individual medley events. In the 200-metre, his first event, he swam a personal best in the semifinals with a time of 1:58.03, and then finished a touch slower in the final the next night to finish seventh overall. In his best event of the Championships, the 400-metre individual medley, Seto qualified first for the final and then won his first long course world title by finishing first in a time of 4:08.69, about half a second ahead of second-place finisher Chase Kalisz of the United States. Seto became the second-fastest Asian performer in the event, behind Hagino, with his time.[5]
During the 2014 Pan Pacific Swimming Championships Seto won a gold medal.[6]
Seto successfully defended his world title in the 400-metre individual medley on the last day of the 2015 World Aquatics Championships in Kazan, Russia.[7] Earlier in the meet, he did not live up to the expectations of others in the 200-metre butterfly and 200-metre individual medley, events in which he was ranked second in the world before leading up to the Championships.[8] [9]
