What is "shirobako"

is an anime television series produced by Warner Entertainment Japan and studio P.A.Works, which handled the animation. The series was directed by Tsutomu Mizushima and aired in Japan between October 9, 2014 and March 26, 2015. A manga adaptation began serialization in ASCII Media Works's Dengeki Daioh magazine in September 2014, and a novel was published by Shueisha in January 2015.

The title Shirobako refers to videos that are distributed to the production staff members prior to its release. These videos were at a time distributed as VHS tapes enclosed in white boxes and are still referred to as "white boxes" (thus the meaning of shirobako) despite the fact that the white enclosures are no longer in use.
