Business has never been better for Japanese anime. And that is exactly why Tetsuya Akutsu is thinking about calling it quits. When Akutsu became an animator eight years ago, the global anime market -- including TV shows, movies and merchandise -- was a little more than half of what it would be by 2019, when it hit an estimated $24 billion. The pandemic boom in video streaming has further accelerated demand at home and abroad, as people binge-watch kid-friendly fare like "Pokemon" and cyberpunk extravaganzas like "Ghost in the Shell." But little of the windfall has reached Akutsu.
