Mami Koyama, Columbia Yurikago Kai
Artist
A vocal pairing of voice actress Mami Koyama and the Columbia Yurikago Kai children's choir, best known for the songs of the Akira Toriyama gag anime 'Dr. Slump Arale-chan.' They performed the bouncy opening 'Wai Wai Koushinkyoku' and the lively insert 'Arale no March,' and contributed the festival-style 'Arale-chan Ondo' for the 'Hello! Wonder Island' film. Their cheerful, sing-along choruses captured the chaotic, good-humored atmosphere of Penguin Village.
