Pre-debut - Pony Canyon
Kokia's next single, "Arigatou...", was the first song that she had fully written and composed herself. It was used as the theme song for the TBD drama, Dotsuzen Oyako. While this did not propel her to stardom in Japan, Kokia became extremely famous in Hong Kong and Taiwan. "Arigatou..." won her the third place prize in the Hong Kong International Popular Music Awards. Popular Cantonese singer, Sammi Cheng, even recorded a Cantonese language cover of the song. This was followed up with Kokia's debut album, Songbird.
