Outsourcing is only good to a point, because how can you keep a local supply of key animators, story board artists, character/BG designers if you don't have a pool of local talent working up the ranks to pull from? It saves money to outsource and pay low wages to freelance workers, but that also means the native talent doing in-betweens and fixing the outsourced work that comes back can burn out or quit because of not being able to afford to eat and house themselves. Even outsourcing is kind of a problem because ultimately it means that for all the money being made in animation very little of it is going to the animators. Nobody is creating the best art when they're treated like a robot on an assembly line and worried about paying their bills.

Japan has to decide if they want to invest in their animation industry or if they'd rather let it die out by killing off the local talent while training animators in other countries to one day replace them.

At least the Frieren one was drawn by a single Japanese artist https://x.com/aoumemimei/status/2012695958824407124

> How much of this is actually drawn in Japan though?

Often the key frames or "important" parts are done in-house with the "mechanical" or boring parts being outsourced.
