Shiritsu Ebisu Chūgaku, commonly known as Ebichu, emerged as a prominent J-pop girl group in 2010 under the auspices of 3B Junior, the talent agency's third division within Stardust Promotion. Initially comprising Kanon (swiftly succeeded by Hinaki Yano), Mizuki, Narumi Uno, Reina Miyazaki, and Rika Mayama, the ensemble evolved over the years, with numerous members joining and departing. In 2012, they unveiled their inaugural album, Ebichū no Zeppan Best: Owaranai Seishun (エビ中の絶盤ベスト～おわらない青春～), which secured the 19th spot on the charts. Their string of hits began in 2012 with "Karikeiyaku no Cinderella" (仮契約のシンデレラ) which reached number 7 on Japan's Oricon singles chart and number 15 on Billboard's Japan Hot 100. Other notable singles include “Go! Go! Here We Go!'” (2012), "Ume" (梅) (2013), "Butterfly Effect" (バタフライエフェクト) (2014), and "Super Hero" (スーパーヒーロー) (2015). Among their albums, Kinpachi (金八) (2015) and Anarchy (穴空) (2016) peaked at number 2 on the Oricon Albums Chart, while Ebicracy (エビクラシー) (2017) claimed the top spot. Their 2019 albums MUSiC and playlist both climbed to number 2, spawning the hit singles "Sing Along, Sing a Song" (シンガロン・シンガソン) and "Trendy Girl" (トレンディガール). Releasing Shiritsu Ebisu Chugaku (私立恵比寿中学) in March 2022, the group commemorated their tenth anniversary with Chukichi (中吉), a few months later, delighting fans in 2024 with eighth studio album Indigo Hour which climbed to number 3 and 4 on the Oricon and Billboard charts, respectively.
