After the war, Ogura became a composer for NHK, and he composed many works that were broadcasted on radio and TV. Meanwhile, he found a new clue to Bartók’s music and pioneered a new composition style with Japanese folk songs and children’s songs. The works of this period include “Dance Suite for Orchestra” (1951) and “Nine Unaccompanied Choruses of Female Voice based on Children’s Song at the Tohoku Region” (1958) which is famous for one of the choruses, “Hotarukoi”.
