2008-2010: Return to entertainment
After Kago departed from Up-Front Agency, her mother attempted to sign her to a new talent agency in her hometown, Nara. Later that year, Josei Seven published an interview with her mother, revealing that Kago left Japan and started residing in New York City. Kago herself later revealed that she had actually not gone to New York, but rather to Los Angeles for three months because she felt like a criminal in Japan. During her stay, she met people who encouraged her, including Winona Ryder, and was able to reflect on her situation. She also considered suicide and cut her wrists.  Kago made a well-publicized return to the entertainment industry in 2008  with plans of pursuing an acting career. She began appearing in multiple Hong Kong movies, including Kung Fu Chefs. On August 25, 2008, Kago released a book entitled Kago Ai Live--Miseinen Hakusho (LIVE--Wei Cheng Nian Bai Shu ). On her blog, she described the book as "a book where I talk to young teens about their various troubles and dreams."  During 2009, Kago also focused on rebuilding her music career. On June 24, 2009, she released her first solo single "No HesitAtIon" [sic] on independent record label In Da Groove. On February 16, 2010, she held her first jazz concert at bar JZ Brat in Tokyo.
