Yōjirō Takita
In July 2008, Ai was featured on an R&amp;B mid-tempo song called "So Special," by Exile member Atsushi, released on Exile's compilation album "Exile Entertainment Best". The song was later re-arranged into an Ai version, and was released as one of the A-sides of her September 2009 single. The other A-side, "Okuribito," is the eponymous theme song for the Academy Award winning Yōjirō Takita film "Departures".
