Anime director Mamoru Hosoda has revealed that he wrote the original plot for Wolf Children in approximately three hours at a Starbucks in Kichijoji, Tokyo.
Hosoda shared the interesting behind-the-scenes detail during the Osaka opening of the exhibition Mamoru Hosoda: The Beginning / Exhibition, which celebrates the 20th anniversary of his film The Girl Who Leapt Through Time.
A newly added exhibit at the Osaka venue features the original plot he wrote when he first conceived the story of Wolf Children.
Speaking about the document, Hosoda revealed:
“I wrote this plot all at once in about three hours at a Starbucks in Kichijoji.”

The original document was approximately seven A4 pages long. Hosoda also explained that, despite being written in such a short period, the plot was already remarkably close to the story that eventually became the finished film.
He clarified that the quick writing process came only after a much longer period of thinking and struggling with the story. After considering numerous ideas, everything suddenly came together, allowing him to write the initial plot in one continuous session.
The filmmaker hopes visitors will enjoy seeing the original document and get a glimpse into how an animated film can take shape from an initial idea.
