Otoboke Beaver is named after a love hotel in Osaka[2] which was located near the high school of one of the band members.
[4][5] The original members included Accorinrin on vocals, Yoyoyoshie on guitar, Pop on drums, and Nishikawachi on bass.
Otoboke Beaver compilation album was released that year, featuring the majority of the songs found on the group's first two mini-albums, with the addition of the "Akimahenka" single.
[8] The band began touring internationally in 2016, including dates at the 100 Club in London and the South by Southwest (SXSW) festival in the United States in 2017.
[10] In 2018, the band traveled over 24,000 miles (39,000 km) in one week to play two slots at the Coachella Festival[11] and a three-date headlining tour in the UK with label-mates Say Sue Me and Leggy.
[13] Pop was replaced by Kahokiss, who had attended the same university music club as the band's founding members almost a decade before.
[17] Along with releasing the single "Dirty Old Fart is Waiting for My Reaction" in early 2020, the members of Otoboke Beaver quit their day jobs to become a full-time touring band.
[22] Their performance at that year's SXSW received coverage from Rolling Stone, which described their set as "both a goddamned riot and tight as hell.
[24] According to its members, the band plays a "fast-paced and aggressive style of punk-rock", with "frequent changes in rhythm and tempo", accompanied by "gang vocals".
[25] Their songs feature love and relationships as regular themes, some based on singer Accorinrin's own experiences,[3][4] and often critique the social roles required of women in modern Japanese society.
[27] Accorinrin specifies Japanese comedian Ken Shimura and theatre comedy group Yoshimoto Shinkigeki as personal influences.
