Shirobako (シロバコ White Box) is a Japanese anime 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.
Aoi will never forget how she felt the day her high school animation club's labour of love was shown at the cultural festival. The sense of awe and the feeling of accomplishment that came with completing their very first project are exactly what encouraged Aoi and her club mates to enter the animation industry in the first place.
But two years later Aoi has graduated, and now that she works as a production assistant for a big-name animation studio, the daunting reality of her job has somewhat diminished her enthusiasm. Despite the long hours and the punishing schedule, Aoi still hopes to fulfil the promise she and her club friends Ema, Shizuka, Misa, and Midori made: to one day reunite and make a real animated feature of their own as professionals!
