Makoto Shinkai has expressed that, unlike his past works, there would be no fantasy or science fiction elements in this film. Instead, the feature film would attempt to present the real world from a different perspective. Shinkai's film gives a realistic view of the struggles many people have to face: time, space, people, and love. The title 5 Centimeters per Second comes from the speed at which cherry blossom petals fall, with petals being a metaphorical representation of humans, reminiscent of the slowness of life and how people often start together but slowly drift into their separate ways. The movie marks the first time Shinkai has worked closely with a full staff of animators and artists.
