Hachiro Kasuga (春日八郎), born Minoru Watabe, was a Japanese enka singer. He has been dubbed "the first enka singer". Having seen Ichiro Fujiyama on stage, he attempted to become a popular singer. After he graduated from the Toyo Music School, he joined the Imperial Japanese Army in 1944, and returned from Taiwan in 1945. He joined Shinjuku Moulin Rouge in 1947 and then King Records in 1949. In 1952, Kasuga made his debut with the song "Akai lamp no Shū Ressha" (赤いランプの終列車), which at first got into the news in Nagoya. His popularity soon became widespread. His 1954 song "Otomi-san" (お富さん) became more successful throughout Japan. This single sold 500,000 copies in a half year, and eventually sold more than one million copies. In 1955, he also released the single "Wakare no Ipponsugi" (別れの一本杉) which he musically sought. The song was composed by Toru Funamura. His music, which was later called enka, had much effect on subsequent popular music of Japan.
