She missed the 2008 Asian Indoor Championship in Doha and began the outdoor season with another national record, recording 51.75 seconds at the Shizuoka International in May. She was expected to improve further at the Osaka GP, but wet conditions slowed the athletes and she finished third with 52.55 seconds. At the national championships, which were also the trials for the 2008 Beijing Olympics, she beat hurdles specialist Kubokura to the title and was selected to represent Japan at the Olympics. At the Olympics in August, she recorded 52.60 seconds in the qualification rounds, which was not sufficient to progress. She returned to the track with the Japanese relay team. While their time of 3:30.52 was not far off the team's national record, it left them in eighth place at the heats stage.
