Michico, T. Kura, and Nao'ymt created and produced "Wild," which was recorded at Tokyo's Azabu-O-Studio with Ryosuke Kataoka's assistance.

Following her commercial resurgence with her studio album Play (2007) and greatest hits collection Best Fiction (2008), Amuro went on a nationwide tour in Japan.

[10] In February, she announced a collaboration with Vidal Sassoon, a hairstyling and haircare company, as well as her involvement in Coke Zero distribution in Japan.

[14] Although the sound was created with a dance-oriented rhythm, Michico and T. Kura revealed that the lyrics had a deeper meaning that reflected Japan's declining childbirth rate.

[9] Musically, "Wild" differs from her previous work, shifting from R&B to an upbeat "aggressive" and "cool" club and electro-pop sounds.

[c] According to Amuro, the majority of the choreography and filming for the video was completed during her Best Fiction Tour, with rehearsal and shooting time being "tight".

[27] Stern compared the music video to the visuals for "Feedback" by American singer Janet Jackson, who inspired Amuro's career.

[15][31] Prior to their initial release, "Wild" and "Dr." were confirmed as commercial themes for Coke Zero and Vidal Sassoon, respectively, with Amuro featured in both campaigns.

[31] For "Wild", Amuro appeared in the commercial in front of a computer-generated speaker, dancing to the song and drinking a bottle of Coke Zero.

"[17] Bradley Stern of MuuMuse wrote, "Namie’s newest is a sweat-worthy stomper with a gloss of dizzying future sounds and manic vocals.

"[18] Tower Records called the song a "exciting dance number" and praised its eclectic mix of sounds and genres.

[36] Since its release, "Wild" has received two gold certifications from the Recording Industry Association of Japan (RIAJ) for exceeding 100,000 physical and ringtone sales.
