The 31st year of the Showa Era (1956) marked the tenth year since Japan's defeat in World War II. It was when Japan took its first step out of post-war poverty to rejoin the international community. In old downtown Tokyo, a teacher and her students try to pass down Doyo (Japanese traditional children's songs) as the root of Japanese cultural identity to the future generations.
