Mieko Nagaoka finished a 1,500 meters swim in one hour, 15 minutes and 54.39 seconds. As Japan's oldest swimmer, she holds 24 world records in swimming.

Aged 100, she is now Japan’s oldest swimmer and even comes to compete at the FINA masters world championships. When she was 84, Nagaoka started masters swimming in Japan. At 88, she made her first appearance at the masters worlds in 2002 in Christchurch of New Zealand and took the bronze in the 50m backstroke. She was back for more in 2004 in Riccione of Italy where she won three silver medals (50m, 100m and 200m backstroke).
She achieved national recognition in Japan when at 90, she set a national record in her pet event, the 800m freestyle. Fresh from her success, she started training with a coach, taking private lessons and trying to improve her record-breaking performance.
Her endeavors have paid off since at 95, she brought it to a whole new level, creating her first masters world record in the 50m backstroke. She currently holds 24 world records and plans to win more medals in both long and short course.
Nagaoka trains four times a week and in her family, swimming transcends every generation, from her son to grandchildren, and she strongly encourages other swimmers to keep swimming as long as possible.
