This Is For

Twice began teasing their fourth studio album on May 19, 2025, with the release of a teaser video titled "Intro: Four". The short clip features all nine members, each wearing a blue skirt with "Four" written across it. The album is the group's first Korean-language studio release since Formula of Love: O+T=<3 (2021). The album's release date and title were announced on May 21. Regarding the title This Is For, member Dahyun explained that it is a play on words that represents the release being the group's fourth full album, as well as a work "for everyone, and for our fans".

On June 9, Twice announced the This Is For World Tour in support of the album. On June 26, the tracklist was revealed via their social media accounts, including five sub-unit tracks, similar to those in Formula of Love: O+T=<3. A few days prior, the group had shared nine solo tracks, one for each member, though none of these songs were included in the album. However, all nine solo tracks would later be on Ten: The Story Goes On. The album was released on July 11 alongside the music video for lead single "This Is For". The deluxe version of the album, released on July 14, includes an extended version of "This Is For" as well as "Takedown" from the KPop Demon Hunters soundtrack.

On July 8, Twice held eight "listening party" sessions where fans listened to the title track before its release. During the last session, Twice talked about the album and screened the "This Is For" music video. To promote the album, Twice performed "This Is For" on the music programs Music Bank, Show! Music Core, and Inkigayo on July 11, 12 and 13, respectively. They also performed songs from the album during the This Is For World Tour, which began at the Inspire Arena in Incheon on July 19. The group then performed "Right Hand Girl" and the extended version of "This Is For" during their headlining set at Lollapalooza on August 2.

Chase McMullen of Beats Per Minute scored the album 84/100, calling it Twice's "tightest and most cohesive album to date" and praising the production and the group's performances. Taylor Swinton of Melodic Magazine called the album "Twice's declaration that they've earned their place at the top" and highlighted the distinct sound of each sub-unit track. Matt Collar of AllMusic awarded the album 4 out of 5 stars, saying that it "finds the K-pop girl group in an upbeat and swaggering dance club mood". Conversely, Raul Stanciu of Sputnikmusic scored the album 2.8 out of 5, criticizing the short length and derivative production on most of the tracks. He overall called the album "a 10th anniversary misstep" and considered it a disappointing follow-up to Formula of Love. Lee Jae-hoon of IZM gave the album 2.5 out of 5 stars, criticizing the songs for lacking substance. He said this is most evident in the sub-unit tracks, which fail to highlight the members' individual strengths.

Idology included This Is For in their list of the 20 best idol pop albums of 2025, calling it a "quintessential K-pop album, with a bright and cheerful K-pop style despite the increased proportion of English lyrics".

This Is For topped South Korea's Circle Album Chart for the week ending July 12, 2025, with 671,771 copies sold. In the United States, the album debuted at number six on the Billboard 200 with 80,000 equivalent album units, as reported by music data tracking firm Luminate. Of these, 68,000 were pure sales and 12,000 were streaming-equivalent units. This Is For is Twice's seventh top-10 record on the chart.
