Tomoko Hagiwara, who owns three national records in women's individual events and one in relay, has decided to draw the curtain on her swimming career after failing to qualify for the Olympics through the National Championships which ended Sunday.

The 24-year-old Hagiwara won the 50-meter freestyle final in 25.62 seconds at Tokyo Tatsumi International Swimming Center but her time was not good enough to clear the Olympic qualifying standard set by the Japan Swimming Federation.

Meanwhile, Jiro Miki set a national record in winning the men's 200-meter individual medley and made history by becoming the first Japanese to clock under 2 minutes in the discipline.

Miki touched the wall in 1 minute, 59.99 seconds to earn his second ticket to Athens after having already earned a berth in the 400 medley.

Takahiro Mori finished second in 2:00.47 and also secured an Olympic spot.
