SYDNEY -- Japan's women's 400-meter medley relay team wrapped up the Olympic swimming competition Saturday with a bronze medal in a national record time as the U.S. team smashed the world record at the Sydney Olympics on Saturday.

The team of Mai Nakamura, Masami Tanaka, Junko Onishi and Sumika Minamoto came home in 4:04.16 -- shaving more than a second and a half off the national record of 4:05.76 they set Friday night.

"We worked as four members of the team, not individuals, to win this prize," Nakamura said.
