Yūzō Kayama(加山 雄三,Kayama Yūzō?, born April 11, 1937) is a Japanese popular musician and actor. His father, Ken Uehara, was a film star during the mid-twentieth century. Yuzo Kayama became a star in the 1960s in the Wakadaishō ("Young Guy") film series.
As a guitarist, he took inspiration from the American instrumental group The Ventures, and performed a form of psychedelicsurf music in the 1960s with his Mosrite guitar. One of his best-known instrumentals is "Black Sand Beach". "Kimi to Itsumademo" ("Love Forever"), another of his compositions, sold over two million copies, and was awarded a gold disc in 1965. At that point it was the biggest selling disc in the Japanese recording industry's history.
In March 2016, Kayama made a special art piece to commemorate 2,500,000 million downloads for the mobile game Terra Battle that is featured as background for the game's title screen.
