Maison Book Girl (written as Maison book girl) was a Japanese alternative idol ensemble established in 2014. Their first album, Bath Room, debuted on September 23, 2015, and the group officially disbanded on May 30, 2021.
History
During Bis' concluding performance on July 8, 2014, Megumi Koshōji revealed intentions to create a new idol unit. The final roster was announced on November 5. Their initial singles, "White" and "Black," were made available exclusively at live events beginning March 14, 2015. On March 27, Kaori Sōmoto departed from the group and Rin Wada joined as her replacement. The debut album Bath Room was released in September of the same year.
On April 30, 2016, the group introduced the EP Summer Continue, followed by the single "River (Cloudy Irony)" on November 30 — marking their first release through Tokuma Shoten. Their sophomore album, Image, was issued on April 5, 2017. Later singles included "412" in July and "Cotoeri" in December. In early 2018, Maison book Girl signed with UK-based label Read The Air Records and dropped "Elude" on June 20, their initial release under Pony Canyon. Their third studio album, Yume, was launched in November.
In 2019, the singles "Soup" (April) and "Umbla" (July) preceded the release of their fourth album, Umi to Uchu no Kodomotachi, which came out on December 18. The compilation album Fiction experienced a delay from April to June 2020 due to the COVID-19 crisis. Maison book Girl concluded their activities after performing at the Solitude Hotel concert held at Maihama Amphitheater on May 30, 2021; a Blu-ray recording of this event was released on August 18.
