I've heard two explanations offered as to why Nozawa voiced Goku in the entirety of his appearances on the show, rather than just as a child. The first is what you said, that Toriyama wanted to demonstrate that Goku was "pure and innocent," and the second is that Toei simply didn't want its young viewers to have to get used to a "new" Goku. The latter explanation seems to make way more sense, as it would explain why every single character in the show kept their first voice actor, regardless of age. It struck me as more of a business/branding decision than an artistic one (although I'm sure some artistic reasons were still involved).Fionordequester wrote:Well, I don't have a problem with Nozawa per say, so much as I think it was kind of a sketchy casting decision to cast her simply because "Goku is pure and innocent and all of that"...
Personally, while I think all of the Japanese voice actors are great, I would have preferred it if they recast the characters when they got older (or younger, in the case of Trunks). Or, I would have preferred it if they recast all the characters depending on their age except for Goku. Having Goku continually voiced by the same actor while surrounding him with other characters whose voices developed "normally," could have potentially been a very charming, funny, and memorable way to reinforce how quirky and odd he can sometimes be.
