Olympic and world 200-meter butterfly bronze medalist Takeshi Matsuda won the 200 freestyle at the National Swimming Championships on Friday.
Matsuda clocked 1 minute, 47.01 seconds for his first title in the discipline at Tokyo Tatsumi International Swimming Center.
Yoshihiro Okumura finished 0.59 behind in second place.
High school swimmer Jumpei Higashi won the men’s 1,500-meter freestyle in 15:11.83.
Takuro Fujii claimed his second straight 100 butterfly crown in 51.94.
Ryosuke Irie advanced to the men’s 200 backstroke final to be held Saturday with the fastest time of 1:56.81.
On the women’s side, Haruka Ueda won her third consecutive 200-meter freestyle title in 1:58.52.
Tomoyo Ueda, the 200-meter individual medley national record holder, won the 100 butterfly in 58.48.
Only two national records have been broken in the first four days of the meet — Kosuke Kitajima in the 50 breaststroke and Masayuki Kishida in the 50 freestyle — due in part to a ban on high-tech swimsuits.
A total of 20 national records were set last year.
