Poppin'Party is a Japanese all-female band that was formed in 2015 as part of Bushiroad's media franchise BanG Dream!.

The group's members are voice actresses who portray fictional characters in the franchise's anime series and mobile game BanG Dream!

In the anime and game, the band is represented by Kasumi Toyama (Aimi), Tae Hanazono (Ōtsuka), Rimi Ushigome (Nishimoto), Sāya Yamabuki (Ōhashi), and Arisa Ichigaya (Itō).

franchise was created by Bushiroad founder Takaaki Kidani with the premise of voice actresses who were capable of playing their own instruments in live performances.

[2][3] He received inspiration for the concept when a staff member attended The Idolmaster Masters of Idol World!!

[2] At her Love Generation concert on February 28, 2015, Aimi announced she would form a band under the BanG Dream!

[7] Composed by Elements Garden's Noriyasu Agematsu, it was released as Poppin'Party's debut single on February 24, 2016.

[9] A week later, Aimi conducted a solo concert at CharaExpo 2015 in Singapore for the franchise's first performance outside of Japan.

[23][24] The two songs were performed by the band at the 3rd Live Sparklin'Party at Tokyo Dome City Hall on February 5.

[29] Poppin'Party's ninth single "CiRCLING" came out on February 21, 2018 as part of a dual-release day with fellow BanG Dream!

was released on July 11 and became the band's first single to appear in Oricon's top five when it peaked at fourth;[22][32] "Excellent (Hey, Let's Go)!"

later served as the opening to Future Card Buddyfight Ace, and Aimi and Nishimoto also voiced characters in the show.

[33] In August, Poppin'Party returned to Animelo Summer Live, where they performed "Tear Drops", "Sparkling Dreaming: Sing Girls", and a cover of "God Knows" from Haruhi Suzumiya, while Ōtsuka and Nishimoto partnered with Maon Kurosaki and Luna Haruna to cover "Shunkan Sentimental" from Fullmetal Alchemist: Brotherhood.

[35] The band's 11th single "Girl's Code", which Real Sound noted had more bittersweet lyrical content in the titular track and its B-side "Setsunai Sandglass" than other Poppin'Party songs, received an October 3 release.

[22] Poppin'Party made a third appearance at Animelo Summer Live in early September, performing "Tear Drops" with the festival's band, "Star Beat!

7th Live at the Budokan on February 23 (the band performed on the third day, titled Jumpin' Music),[44] No Girl No Cry with Silent Siren in May,[13] and a guest appearance at Rock in Japan Festival on August 11.

8th Live at Fuji-Q Highland Conifer Forest; the band was joined by Morfonica and Pastel Palettes' Ami Maeshima with Raise A Suilen, while RAS' Raychell and Roselia's Aina Aiba performed "Straight Through Our Dreams!"

[53][54] On February 23, the band held a joint "Friendship Live" with Morfonica, titled Astral Harmony, at Yokohama Arena.

[55] The two bands played at Animax Musix 2021 at Yokohama Arena on November 20, which was preceded by Ōhashi being the show's opening act in which she performed her solo song "Noisy Love Power" from the anime Magical Girl Ore.[56] Aimi and Ōtsuka also hosted a series of acoustic music shows, called Kasumi and Tae's Stay After School Tour, with stops at Zepp's Namba (October 17), Nagoya (November 7), and Yokohama (November 17) venues.

One of the single's supporting tracks "Introduction" was written by Ayase of Yoasobi in the franchise's first "tie-up" partnership song with unaffiliated artists.

[19][72] Fictionally, Poppin'Party is formed by Kasumi Toyama in her journey to rediscover the "Star Beat", and the astral theme is represented through their lyrics and outfits; the latter, which resemble school uniforms, feature a celestial motif.

[74] For the third season, Poppin'Party enters the Girls Band Challenge competition alongside Roselia and Raise A Suilen.

Nakamura has noted that the first letters in the names of Kasumi's bandmates spell "STAR" (Sāya, Tae, Arisa, Rimi), which reflects the band's starry image but is coincidental.

The character designs were loosely modeled after their actresses to reflect their musical abilities,[2] while shared personality traits include Tae and Ōtsuka owning a large collection of pet rabbits.

[81] Certain events in the anime mirror experiences at the franchise's lives; for instance, Kasumi's voice loss in the first season is based on the same occurring to Aimi during the band's debut show.

Star Beat by Nakamura and Aya Ishida, contained numerous differences in character traits that were retconned in later media.

[79] Elements Garden's members like Agematsu and Junpei Fujita oversee the songs' composition and arrangement.
