Chaotic Wonderland

Chaotic Wonderland is the first Japanese-language extended play by South Korean boy band Tomorrow X Together. It was released by Big Hit Music and Universal Music Japan on November 10, 2021. Thematically, it follows their previous album The Chaos Chapter: Freeze, released in May 2021. The EP contains two Japanese versions of previous Korean releases, their first English single "Magic", and an original Japanese song "Ito".

Background
TXT began 2021 by releasing their first Japanese studio album Still Dreaming on January 20, marking an end to The Dream Chapter series. Later, in May 2021 they began The Chaos Chapter with the release of their second Korean studio album named The Chaos Chapter: Freeze and its repackage album The Chaos Chapter: Fight or Escape on May 31 and August 17 respectively. On September 6, 2021, Big Hit Music announced that TXT would be releasing their first Japanese extended play on November 10, 2021. Originally, the Japanese featuring artist for "0x1=Lovesong" was undisclosed. Beginning October 22, Universal Music Japan teased the reveal with a set of clues via Twitter. The artist was revealed five days later as Ikuta Lilas, also known as Ikura, the main vocalist for Japanese musical duo Yoasobi.

On September 20, the also-undisclosed Japanese original song was revealed to be "Ito", written by Japanese pop-rap male vocal quartet Greeeen. The song revolves around the themes of attachment, like two people who are each one half of a thread meeting to make one thread. It comes from the feelings you get from forming a deep relationship with someone. Ito is also featured as the opening theme for the TV Tokyo's television drama, Spiral Labyrinth – DNA Forensic Investigation (らせんの迷宮～DNA科学捜査) which began airing on October 15, 2021.

Release and promotion
In September, it was announced that TXT would appear in the December 2021 edition of Numéro Tokyo, slated for release on October 28. On October 26, two days prior to the release, the front covers were revealed with a snippet about their interview. The group also appeared on the front cover of "ar"'s December 2021 issue, released on November 12. This will be the first time that a male overseas artist has featured on the front cover.

On November 3, 2021, following the TV-sized release for Spiral Labyrinth, "Ito" was pre-released as a digital single available on streaming platforms worldwide.
