The Yamaha Popular Song Contest (ヤマハポピュラーソングコンテスト, Yamaha Popyurā Songu Kontesuto), generally known as Popcon (ポプコン, Popukon), was a Japanese popular music contest which ran from 1969 to 1986. It was sponsored by the Yamaha Music Foundation and was held annually (later, twice a year) at the Yamaha Resort Tsumagoi in Kakegawa, Shizuoka, Japan.
The grand prix winners were to be qualified for the World Popular Song Festival.
