東京ビートルズ

Group Sounds (often abbreviated GS) is a mid–late 1960s Japanese rock movement that fused Western Beat- and garage-derived rock with domestic kayōkyoku songcraft. Bands typically performed in matching stage attire, used electric guitars, organs, and tight vocal harmonies, and initially sang many songs in English before moving toward Japanese lyrics. GS crystallized the moment Japanese popular music embraced the contemporary British and American rock sound (Merseybeat, surf, garage) while retaining local melodic sensibilities and production aesthetics. Its studio and media practices proved pioneering for modern Japanese pop and rock, helping establish band marketing, television tie-ins, and teen-idol crossovers that later informed J‑pop and the wider rock industry.
