Mao Ichiyama and Suguru Osako each secured berths at the Tokyo Games based on the results of Sunday's Nagoya Women's Marathon and Lake Biwa Marathon, the final selection races for Japan's Olympic marathon team.
Ichiyama won the Nagoya Women's Marathon in a race record time of 2 hours, 20 minutes and 29 seconds to claim the third and final spot available for Japanese women. Yuka Ando finished second in 2:22:41.
The 22-year-old Ichiyama pulled ahead after passing the 30-km mark and ran the remainder of the rain-soaked course in Nagoya uncontested. Her time satisfied the 2:21:47 conditional mark set by Mizuki Matsuda at the Osaka Women's Marathon in January.
