Yū Aku
She stayed busy with her singing career, however, with some appearances in musicals and on television, but was not getting near the top of the charts. In 1972, she made the first of her numerous comebacks, with the smash hit single "Donimo Tomaranai", which became the second biggest hit of her career. The song was written by the accomplished writing team of Yū Aku and Shunichi Tokora, who also wrote hits for Pink Lady, Finger 5, and Momoe Yamaguchi. They later wrote more songs for Yamamoto, including "Jin Jin Sasete", "Kuruwasetaino", and "Neraiuchi". Yamamoto also had a brief turn as a voice actress in 1974, providing the speaking and singing voice of Princess Margaret in Gisaburo Sugii's anime movie version of "Jack and the Beanstalk". She also played the character of Mari in the original "Kamen Rider" TV series starting in 1971.
