It seems this particular detail was left ambiguous both on-screen and off. Miyazakiās right-hand man and Studio Ghibli producer Toshio Suzuki reckons it was about three days, based on the dust and leaves in and around her parentsā car. But itās hard for anyone to know for certain ā especially as the passage of time seems to change as one passes through the tunnel to the spirit world.
One fan asked about the inspiration behind the food stall where Chihiroās parents sat down to eat at the beginning of the film. Rather than using one particular location as a model for the unmanned yatai (street stall), Miyazaki drew inspiration from the eateries and general atmosphere around Tokyoās Yurakucho and Shinbashi districts.
According to the studio, most of the male workers at the bathhouse are frogs while the female staff are actually slugs. The studio said this may be a reference to how the senior staff at Studio Ghibli initially all look the same to new hires. A character like Rin, who appears human to Chihiro, apparently only looks that way because sheās one of Chihiroās direct seniors, so Chihiro can tell her apart from all the other bosses.
Miyazaki reportedly created the characters of Chihiro, Yubaba and No Face to represent three different sides of a single person. No Face supposedly represents some of the darker personality traits we all struggle against, like obsession and greed. Apparently, No Face was named āNo Faceā to emphasise that people are multifaceted beings who are more complex than you would know judging by just one single aspect of their character.
Ghibli wouldnāt give us a definite answer to this one. Instead, they pointed us in the direction of the 1971 childrenās book āKrabatā by Otfried Preussler. The fantasy tale is about love and black magic, and reportedly inspired the fateful test Chihiro had to pass to be reunited with her parents.
Looking back on it now, the director canāt recall why he made this choice, but when making the storyboard for the scene, Miyazaki specifically added a note saying āDragon Ball styleā. The point is, Yubaba may be a grandma, but sheās a super powerful granny who can also fly through the air.
Unfortunately, that doesnāt mean a sequel is in the works, but seeing as Haku is actually the spirit of the river from near Chihiroās childhood home, the two friends could be reunited if Chihiro revisits that same river one day.
