In 2022, Otsuka released a new version of the song entitled "Smily 2" (stylized as "SMILY2"), with new vocals and different arrangements. The song was released as a digital single on July 6, 2022.^[1][2]

The song was commissioned by Häagen-Dazs Japan for a web commercial campaign to promote their new limited-edition Mini Cup Creamy Gelato flavors, Pistachio & Milk and Mixed Berry & Cream Cheese, launched on June 28, 2022. The commercial was entitled "Neri Motion," to promote the Häagen-Dazs' "mixing and eating" (neri-tabe) concept, where consumers mix two flavors within a Häagen-Dazs Mini Cup. The web commercial was published on June 27, 2022, and it features Otsuka alongside dancers Bito and Piyote doing a number choreographed by SIS, a Japanese sister dance duo which gained popularity on TikTok.^[3] The choreography also incorporates "mixing" movements to reflect the "neri-tabe" concept.^[2]

The single's cover artwork features a design by Otsuka herself, depicting a smile drawn on the surface of Häagen-Dazs ice cream, aligning with the song's cheerful theme and the brand's campaign. The song was arranged by musician Shingo Sekiguchi.^[2] Otsuka described this new version as "perfect for drives or walks", while Sekiguchi declared: "I hope that we successfully blended the original song's evergreen melody with my take on a modern sound. With the dry beat and crisp guitar cutting in 'Smily 2,' I would be thrilled if listeners can feel [its] summer vibe".^[4]

This song was the only new song released by Otsuka in 2022, and to date has not been included on any album.
