sunsoogirl (三四少女) is a Japanese group formed in October 2021 that plays indie rock and J-rock. Blending guitar-driven arrangements with a contemporary Japanese rock sound, the band has been building visibility through both commercial and anime-related releases.
In March 2026, their song “Aoi Haru” was selected as the web CM song for ABC-MART. The group then announced its major debut in April 2026 with the TV anime Otagyaru ending theme “一生仲仔,” and the music video premiered the same day. That same song later debuted at No. 1 on the Heatseekers Songs chart, adding another notable milestone to sunsoogirl’s rising profile in Japan’s rock scene.
