5 Centimeters per Second

5 Centimeters per Second (2025) is a Japanese live-action film directed by Yoshiyuki Okuyama, adapted from Makoto Shinkai's 2007 anime. It follows Takaki Tono and Akari Shinohara across roughly two decades, presenting both characters' perspectives rather than Takaki's alone.

In the early 1990s, Akari transfers to an elementary school in Tokyo and quickly befriends Takaki. They bond over reading and shared time together. During a spring day amid falling cherry blossoms, Akari tells Takaki that 5 centimeters per second is the speed at which cherry blossom petals fall — a detail that becomes emblematic of their relationship. Their happiness is cut short when both families are forced to relocate: Takaki to Kagoshima, Akari to Tochigi.

Before Takaki's move, the two arrange a final meeting at Iwafune Station in winter. Despite severe snowstorms and severely delayed trains, Takaki arrives late in the evening to find Akari still waiting. Beneath a large cherry tree they share their first kiss, and they make a promise to reunite in March 2009, when a comet will pass close to Earth.

Years later, during high school, Takaki has grown distant and withdrawn, frequently absorbed in his phone. A classmate, Kanae Sumida, harbors unrequited feelings for him but is unable to express them. Takaki and Akari are no longer in regular contact by this period. Kanae ultimately never confesses her feelings.

As adults, Takaki works as a programmer leading a monotonous life. He enters a relationship with a woman named Mizuno Risa, but she senses his emotional unavailability — his inner life remains anchored to the past. He eventually quits his programming job and takes work at a planetarium, drawn there in part by his childhood astronomy interest and the memory of the comet promise.

Akari, meanwhile, has built a full adult life. She works at a bookstore, maintains an active social circle, and has already married. She is preparing to relocate to Australia. She looks back on her childhood bond with Takaki as a cherished but resolved chapter.

As March 2009 approaches, the planetarium where Takaki works hosts a show. Akari attends; afterward she discovers Takaki's name on the promotional materials, realizing they nearly intersected. Takaki goes to the cherry tree at the appointed hour hoping she will appear. She does not.

The planetarium director later tells Takaki that a young woman once came by and mentioned an unfulfilled promise, asking that the friend connected to it be encouraged to let it go and move forward — this was Akari's quiet farewell message to Takaki.

In the film's key scene, Takaki and Akari briefly glimpse each other from opposite sides of a passing train. Their reactions diverge: Akari continues on her journey; Takaki stands still, watching the train go. The image crystallizes their emotional asymmetry — she has accepted the passage of time while he has been suspended in it. After learning of Akari's message through the director, Takaki begins to find a measure of peace and release from his long attachment to the unfulfilled promise.
