is a Japanese rock band from Tokyo which is signed to Sony Music Entertainment Japan. It began activities in 2015 after members Hirose Hirose and Emi Okamoto made a collaboration; they would later be joined by bassist Ryà Âhei Nagashima, guitarist Tarà  Miura, and drummer Rui Sekiguchi; Hirose would later leave the band in 2021. The band's music has been featured in movies, TV dramas, and anime series such as Hori-san to Miyamura-kun.
The band's activities began in 2015 when Hirose Hirose, a member of the band Nicoten, decided to hold a live performance to celebrate his 25th birthday. He wanted to form a band with a female lead vocalist for the occasion, and decided to collaborate with musician Emi Okamoto, who at the time was a member of the band The Love Ningen and someone whom he had collaborated with previously. Needing a bassist, Hirose invited a friend, Ryà Âhei Nagashima of the band The Telephones, to join the band; Nagashima in turn invited Louie Sakaguchi to serve as the band's drummer. The band debuted on June 8, 2015, as a highlight of Hirose's birthday live. The band's name came after Okamoto saw a bar named Philippine Pub Friends and sent photos of it to the other band members, who decided that the word Friends would make a good band name. In 2016, Tarà  Miura, formerly of the band Holidays of Seventeen, joined Friends.
Many of the band's early releases were only released at their live performances or by mail order, although their first mini-album Show-Time sold over 3,000 copies. Their first full album was released on April 5, 2017. Their next release was the mini-album on November 22, 2017. This was followed by the extended play on March 21, 2018. They released their second album on August 1, 2018.
The band released the single on June 26, 2019; "Tanoshimou" was used as the theme song to the film Bento Harassment, while "I o You" was used as the ending theme to the television drama What Did You Eat Yesterday?.
In December 2020, it was announced that Hirose would suspend activities with the band and would not appear in their upcoming performances; he would ultimately leave the band in April 2021 after his contract was canceled over unspecified issues. The band released the single on March 17, 2021; the title song was used as the ending theme to the anime television series Horimiya. They released their third album Solar on August 4, 2021.
