Hibari Misora
New singers such as Hibari Misora, Hachiro Kasuga, Michiya Mihashi and Chiyoko Shimakura became popular when old singers became unpopular. The period between around 1955 and 1964 saw the popularity of "kayōkyoku". Around that time, Japanese composers went on to establish their own genres such as Toru Funamura and Minoru Endo's "Enka", Tadashi Yoshida's "Mood Kayō", and Hachidai Nakamura and Hiroshi Miyagawa's "Jazz". Masao Koga renounced his pre-war musical style, approaching Hibari Misora.
