Japan as a whole lives on it's past glories.True but really it does say a bit when Japan cannot really shell enough to bring in the big guns for animation as consistently as before but still I don’t see Japanese voice actors being replaced given there niche and appeal but I do see Chinese voice greatly improving to the point where their appeal will broaden to being on a similar level to a Japanese voice actor (I mean from what I saw of recent games, especially honkai impact I see the voice acting quality improve a lot of the past few years since it’s begging). Still this speaks volumes as to how much the Chinese entertainment scene has improved and still have room to greatly improve and expand. This is compared to the stagnation of the Japanese entertainment industry in general that seems to be stagnating as a whole whilst doing little to innovate and really the only selling point these days are their voice actors and past glories attached
Even of their largest electronics companies states this, although not outright. But Japan is not to be underestimated. Japan still owns many legacy IP's and controls many legacy industrial processes, which give it a strong advantage. However, Japan is severely lacking in development of new technologies, and thus depends on IP on their legacy processes.
