The official website for Dragon Ball Kai has noted that there will be even more new voices for the “refreshed” version of the TV series currently airing in Japan. In its original airing, both (the younger version of) Dende and Cargo (all… what?… one of his lines…?) were played by Tomiko Suzuki, who unfortunately passed away back in 2003.
Taking over the role for Dende will be the currently-somewhat-prolific Aya Hirano, most recently associated with the Dragon Ball franchise as the voice of Bulma in the Japanese dub of Dragon Ball Evolution, and belting out “CHA-LA HEAD-CHA-LA” karaoke-style in the ending of episode five of Lucky Star.
Taking over the role of Cargo will be Satomi Satō, a relative newcomer perhaps best known for her role in K-ON!.
