In January 2011, she helped Kyoto to win the Inter-Prefectural Women's Ekiden and was fifth at the Osaka Marathon. The Yokohama Women's Marathon the following November saw her top the podium for the first time in the event. In spite of hot conditions and poor pacing, she ran a personal best of 2:26:32 hours and defeated her more favoured compatriot Yoshimi Ozaki. She won the first leg of the 2012 Inter-Prefectural Ekiden which opened a lead for the Osaka team to take the women's title. Her run in Yokohama gained her a spot for the 2012 Olympic Marathon, where she came sixteenth overall.
