Did you know?!Facts and trivia about Mirai (2018)
Can contain spoilers, watch the movie first.
- Mamoru Hosoda was inspired to write Mirai after watching his three-year-old son react to a new baby sister; the boy threw a jealous tantrum over the attention his parents gave her, which prompted Hosoda to make the film's protagonist four years old.
- For the sequence where Kun is stranded alone at a train station, director Mamoru Hosoda consulted Hideo Shima, the Japanese engineer who designed Japan's bullet train, to build a model of the shinkansen that would look more frightening.
- Composer Masakatsu Takagi's first score for Mirai was pop-oriented with Brazilian influences, but director Mamoru Hosoda rejected it and asked for something simpler and more reflective of family.
- Because Mirai's protagonist is only four years old, Mamoru Hosoda brought his own children into the Studio Chizu office so the animators had real children to sketch and animate from.
- The story of Kun's great-grandfather in Mirai was loosely based on Mamoru Hosoda's wife's great-grandfather, who likewise worked on warplanes and was injured in wartime conflict.
- The house Kun's father designs on screen in Mirai was designed for the film by real-life architect Makoto Tanijiri, part of Hosoda's push for authenticity using professionals outside the animation industry.
- The paper cutouts of strangers Kun meets in Mirai were designed by Tupera Tupera, the children's book author and illustrator duo whose books Hosoda's son loves.
