• I. Introduction

    Apeace (Korean: 에이피스; Japanese: エーピース) is a 12-member boy group primarily active in Japan.

    The group originally debuted with 21 members in 2010 as Double B 21 (Double B) before re-debuting under their current name in Japan in 2011. Since then, the group is only active in Japan.

    II. Career

    The original line-up of Apeace was called "Double B 21" (or "Double B"). It contained four sub-units: "Sky," "Earth," "River," and "Burning." Sky debuted with the single "One" on Mnet's "M Rookies" on 25 August 2010. All members appeared together for the first time on 24 October 2010 at Lotte World and released their single "S.O.S" on 27 October. In December, they changed their name to "A-peace" and they promoted S.O.S in Thailand.

    Their name changed for a third time, officially becoming Apeace (without a dash). They released their debut mini-album in June 2011 called "We Are the One" as well as a music video for the song "Lover Boy" on 7 September 2011. The group was split into three sub-units with 7 members each. On 28 November 2011, Son Yu-chang left to continue studying composition and Lee Sung-woo left because of backache issues. They were replaced by Kim Won-shik and Lee Myung-eun, respectively.

    In March 2012, Apeace released a mini album called "We Are the One" in Japan. The song was used for their first commercial, for Glico Bitte. They held their first fan tour in Seoul in April, 2012. On September 29, they launched their major Japanese debut with the release of their first full-length album called "1st ALBUM Apeace."

    Apeace released a single album on February 13, 2013 titled "X.O.X.O. ~Dreams~/Never too late," to celebrate Valentine's Day.

    Members Kim Seung-hyung, Kim Seung-hwan, and Jeong Ho-young left Apeace on April 23 to fulfill their mandatory military service. They were replaced by Yun Jun-sik, Kim Doo-hee, and Yoo Jae-deok (J.D), respectively.

    Apeace released a compilation album entitled "For You" on December 5, 2014, featuring solo songs by members Kim Wan-chul, Yoo Jae-deok, Oh Se-hyeon, Jeong Young-wook, and Hong Sung-ho. Apeace's second full-length album entitled "Colors" was released in Japan on December 24.

    On November 18, 2015, they released a single album "Just Once Again" with an accompanying PV. "Just Once Again" contains the theme song to their new ODS: Once Again, Apeace's first starring movie.
