Whilst Studio Ghibli are taking a break form making feature films the studio is still active working on short film productions and their latest has been produced for the energy company Marubeni Shin Denryoku who are touting their shift towards low-pollution, renewable wind, water, and solar-based energy production. The source of this film is the 12th century “Choju Jinbutsu Giga” or Scrolls of Frolicking Animals which are considered to be the earliest examples of manga in Japanese history and were chosen by Ghibli as a symbol of the natural beauty of pre-industrial era Japan.
