Picked up on the Japanese blog Yaraon!, this manga, titled 90% Job Turnover!? The Truth About Animators is more than just an 8-page look at the job description of Japanese animators, but rather, a boots on the ground examination of the industry. The manga is short but it makes its point fairly bluntly: making anime is not for the faint of heart.
While this manga is not representative of ALL anime production studios, it does seem to reflect the general atmosphere. In the above gallery, you can read the manga, which I have translated from its original Japanese.
