札幌国際ハーフマラソン
Her first marathon race came at the beginning of 2010, when she entered the Osaka Women's Marathon. She was close to the leaders in the first part of the race and eventually finished in 2:29:12 hours in eighth position. Under the tutelage of Sachiko Yamashita, she continued to progress and was a close second to Yuri Kano at the Sapporo Half Marathon. This performance earned her an international debut at the 2010 IAAF World Half Marathon Championships and her thirteenth-place finish at that event helped the Japanese team, including Yoshimi Ozaki and Ryoko Kizaki, take the team bronze medals. She returned for Dai-Ichi Life at the Corporate Ekiden Championships and placed second in her stage behind Risa Shigetomo of Tenmaya – a outcome matched in the final team rankings.
