On the Oricon Singles Chart, Ai has six top-ten singles, her highest peak being number two. On the Billboard Japan Hot 100, eight of Ai's singles have reached the top-ten, her highest peak position at number two.
Ai had her first Oricon Singles Chart entry with "Shining Star" from her debut studio album, My Name Is Ai (2001). Her fourth studio album, Mic-a-holic Ai (2005), featured "Story", a sleeper hit that went on to become one of best-selling multi-format singles in Japan. Ai's 2006 single "Believe" became her highest charting single on the Singles Chart, peaking at number 2. Ai's first entry on the Billboard Japan Hot 100 was "Taisetsu na Mono", peaking at number nine. In 2011, she released "Happiness", a campaign song for The Coca-Cola Company. The song went on to become one of her best performing singles in the 2010s with 3 million digital sales reported from the RIAJ, peaking at number 2 on the Japan Hot 100. "Voice", from Moriagaro (2013) tied with "Happiness" in terms of peak chart positions, also reaching number two on the Japan Hot 100.
In 2016, Ai released "Minna ga Minna Eiyū", originally a 100-second song used for promotional campaigns by au. The song was exclusively released to au's music services. Becoming a sleeper hit, the 100-second version received a Platinum certification from the RIAJ. Ai later recorded and released a full version of "Minna ga Minna Eiyū" in February 2016. The full version peaked at number four on the Japan Hot 100 and was certified Gold. Ai scored another top-five hit in 2016 with "No More', a duet recorded with Atsushi. She followed up the singles with her first triple A-side single, "Happy Christmas / Heiwa / Miracle". The maxi single went on to peak at number fifty-five and as of 2025 was her last physical single release.
Ai's 2017 single "Kira Kira" featuring comedian Naomi Watanabe from a deluxe reissue of Wa to Yo (2017) peaked at number nineteen and was nominated for the Grand Prix Award at the 59th Japan Record Award. Since 2019, Ai's singles have diminished in sales, primarily charting in sub-charts of the Japan Hot 100 and Oricon charts. "Aldebaran" from Dream (2022) became her first charting single on the Japan Hot 100 since "Kira Kira", debuting and peaking at number thirty-seven. It went on to become her first top-ten single on the Oricon Digital Singles Chart and being certified Gold by the RIAJ.
