1.
song, ballad, popular song
A general term for songs, especially popular songs or ballads. Often used to refer to Japanese popular music from the Showa era through the early Heisei era, as distinct from more modern J-pop.
Usage
歌謡 refers broadly to songs, but is particularly associated with Japanese popular music (kayōkyoku) from roughly the 1930s through the 1980s. The term carries a somewhat nostalgic nuance compared to modern terms like J-ポップ.
