That same year she also won the Kyoto Half Marathon in a personal best of 71:11 minutes.

She also made her debut over the marathon distance and surprised more seasoned competitors by taking fourth place with a run of 2:29:13 hours at the Nagoya Marathon.
At the 2011 Osaka Ladies Marathon she led the pack and split away to duel against Yukiko Akaba. Ito managed second place and a new best of 2:26:55 was enough to gain selection for the 2011 World Championships in Athletics. At the World Championships Marathon in Daegu she finished 22nd overall, but was last out of the five-woman Japanese squad. At the end of the year she set a best of 70:03 minutes to come fourth at the Sanyo Half Marathon.
She remained in good form in the 2012 season, running 70:39 for fifth at the Kagawa-Marugame Half Marathon and a best of 2:25:26 hours for fifth at the Nagoya Marathon. A win at the Sapporo Half Marathon followed in July and this led to an appearances at the 2012 IAAF World Half Marathon Championships, where she was ninth and helped the Japanese women to the team bronze. In a quick field at November's Yokohama Women's Marathon she was the fifth-placer and second Japanese with a time of 2:27:06 hours.
