A YT channel I subscribe to yet don't watch very often did a piece on underpaid and overworked animators in Japan. They earn on average $300-$500 a month which is even less than a part-time high school worker. Rookie/Newbie animators have to depend on crowdfunding to pay for their needs, such as living in a dormitory with others to cut on costs for rent and utilities.
It's actually quite shocking to me because even those given a monthly salary only make around $500-$600/month. The reason is explained in that there is a low, set budget for animation projects which a majority of is taken by advertisers. It's also apparently affecting those who want to be in the industry, but due to being unable to sustain themselves even working 15+ hours per day most quit or just don't enter into an animator career.
Honestly, I didn't think they would be pay so low that even a high school worker would get more per month which says a lot about the state of the anime industry right now.
