Double Olympic champion Kosuke Kitajima set another national record on Saturday in the Speedo LZR Racer, raising more concerns about contractual obligations for Japan's swimmers to use domestically produced suits at the Beijing Olympics.
Kitajima, who won the men's 100 and 200-meter breaststroke at the 2004 Olympics, clocked a time of 27.65 seconds in the men's 50-meter breaststroke at the Japan Open, breaking his own national record of 27.78 set at the 2005 World Championships in Montreal. Overall, five national records were broken on Saturday by swimmers wearing LZR Racers: 18-year-old Ryosuke Irie (men's 200 backstroke, 1:54.77), Reiko Nakamura (women's 200 back, 2:08.34), Takeshi Matsuda (men's 400 freestyle, 3:47.28) and Yuka Kato (women's 50 butterfly, 26.34).
