Production

 One of Hosoda's motivations for working on this film was that people around him had started raising children, and he "saw them shining as they became parents." In an interview with Anime! Anime! in February 2013, Hosoda explained why he chose the setting of Wolf Children despite the fact that it is a story about raising a child: "It is generally taken for granted that children are raised and then grow up. But for the actual people involved, it is not natural at all. In order for the audience to share this feeling, I thought it would be good if we all shared an experience that no one else had (raising a werewolf child)."^[7]

In an interview with Famitsu, Hosoda said, "I used to take it for granted that people would have children. However, after getting married, I began to realize that raising children in the city is a hardship in terms of the environment, such as public support, and that living in the countryside is not necessarily easy, and that there is a hardship of not having anyone of the same age. I wanted to make a film about such endurance." Human parenting cannot be done in complete isolation, and the reason for choosing wolves as the material for the project was that "wolves are very family-oriented, and they are disciplined animals that have a leader who leads the pack and lives with the whole group in mind."^[8]

The setting of the early part of the story, "a national university on the outskirts of Tokyo," is modeled after Hitotsubashi University in Kunitachi, Tokyo.^[9][10] In addition, the countryside where Hana moves to is modeled after the undeveloped woodland in Toyama Prefecture. The backdrop of the film depicts the landscape of Nakaniikawa District's Kamiichi, Hosoda's hometown, and the neighboring town of Tateyama, and it was divulged that the former mayor of Kamiichi, Naoshi Itō, approached Hosoda to "make a film based on the town." The old house that served as the model for Hana's house was a private home owned by Masao Yamazaki, who lived in Kamiichi. In 2007, five years before the movie was released, Yamazaki passed away, and the house was considered for demolition, but it was chosen as the model for Hana's house, and after the movie became a big hit, it was opened to the public by the owners (relatives of Yamazaki) and volunteers (as of 2015).^[11] The elementary school that Ame and Yuki attended was modeled after Tanaka Elementary School (only the gymnasium is still in existence). The yakitori with sauce that appears in the film is oidare yakitori, a local dish from Ueda, Nagano, where Hosoda's wife's parents live.
