She won her first major marathon in 2010: seeing off competition including Derartu Tulu, she won the Nagoya Women's Marathon in 2:27:11, which also doubled as a national championship victory. She was happy with her second ever marathon win, saying: "I have promised myself to challenge for a victory many times before but I was unable to attain my goal previously...this time I was determined to win". A victory at the Sapporo Half Marathon in July came after as she held off a challenge from Azausa Nojiri to keep the lead in the final stages.
