Satomi Suzuki and Rikako Ikee set national records Tuesday in the women’s 50-meter breaststroke and 100-meter butterfly, respectively, on the opening day of the Japan Swimming Championships.
Suzuki clocked 30.64 seconds in a qualifying race over the non-Olympic distance at Tatsumi International Swimming Center, slashing 0.02 second off the previous record she set at last year’s nationals.
The 27-year-old — who won silver in the 200 breaststroke, as well as bronze in the 100 breaststroke and 4×100 medley relay at the 2012 London Games — later won the event after clocking 30.95.
Seventeen-year-old Ikee qualified fastest for Wednesday’s 100 butterfly final after clocking 56.58 seconds in the semi, shaving 0.28 seconds off the national record she set at the 2016 Rio de Janeiro Olympics.
Yasuhiro Koseki was fastest in qualifying for the men’s 100 breaststroke final, swimming 58.96 seconds in the semi, while Ryosuke Irie was fastest in the men’s 100 backstroke semi, clocking 53.39 seconds over the distance for which he earned bronze at the London Games.
