The sense of belonging in “not here”

5 Centimeters per Second

The sense of belonging in “not here” is a recurring motif through which the story connects personal displacement to place, memory, and intimacy. The phrase first belongs to Kanae Sumida’s bodily struggle in the sea, then becomes a way she recognizes Takaki Tohno’s estrangement—and, by implication, her own. In parallel, Takaki and Akari Shinohara experience relocation in opposite directions: places that once felt alien can become home, while even a chosen destination may fail to feel like belonging. The motif’s force lies in that instability: a person can feel out of place somewhere familiar, or carry loneliness into a place they have deliberately chosen.

The Phrase and Its Shifting Meaning

While paddling out through repeated waves, Kanae thinks, “Not here.” She is trying to get farther out, and repeats the words inwardly as though they were a spell. At first, the phrase is attached to an immediate physical circumstance: the water is heavy, the waves keep coming, and she is not yet where she needs to be. But the thought abruptly recalls Takaki to her. The movement from exertion to recognition makes “not here” more than a judgment about location. It becomes a language for an unease she recognizes in another person because she has felt something similar herself.

Kanae associates that unease with particular moments in Takaki’s routine: texting someone near a convenience store after school, waiting in the deserted motorbike parking lot, and appearing behind the school early in the morning. She imagines the words “Not here” as a scream coming from him, then understands that his sense of not belonging is not his alone. This remains Kanae’s perception, not a confirmed statement by Takaki; the distinction matters. The motif makes an inward feeling legible through her intuition, while leaving the gap between what she senses and what he says intact.

Her surf session also resists a simple image of finding one’s place. Repeating the words does not make the sea yield to her: a wave lifts her before she is ready, collapses, and pitches her headfirst into the water. She surfaces clinging to her board, coughing after swallowing seawater, with tears and snot on her face. The physical mishap gives the motif an unsettled, embodied form. The wish to get somewhere else is real, but reaching it is not instantaneous or guaranteed.

Moving Between Places

Takaki’s childhood supplies an earlier history of displacement. Just before third grade, he moved with his parents from Nagano to Tokyo. On the train between Omiya and Shinjuku, the buildings stretching across the view seemed utterly unlike the mountainous scenery he knew. He worried that he would have to live among buildings as far as he could see and nearly cried. Five years later, at thirteen, he could recognize that he had survived the move; he also thought Akari had saved him and hoped that he had done the same for her. His memory links adaptation to a relationship, rather than presenting it as a solitary achievement.

The moves do not produce a simple progression from alienation to settled belonging. After high school on Tanegashima, Takaki moves to Tokyo for university and rents a small apartment within walking distance of Ikebukuro Station. Although he had lived in Tokyo from ages eight to thirteen, he remembers only Setagaya Ward and finds the larger city almost unknown. Its residents and streets strike him as coarse and indifferent, sharply unlike his memory of a calmer, more refined Tokyo. Yet he tells himself that he is there of his own free will. In the apartment, with boxes still unpacked, he reflects that everywhere is the same. The contrast is not between a bad place and a good one, but between a place imposed by circumstance and one he has chosen—and the persistence of estrangement in both.

Akari’s childhood move to Iwafune provides a counterpoint. She had been born in Utsunomiya, spent early childhood in Shizuoka, and lived in Tokyo from fourth through sixth grade. When she arrived at Iwafune Station with her mother, her father was waiting on the platform after going ahead. Though she had visited her grandparents there before, the small, quiet town felt desolate as a place to live. She was so homesick for Tokyo that she nearly cried and thought she should not be living there. Years later, however, the same town and her parents have become dear to her; she calls it her hometown and hates leaving it. The platform remains physically small, but its meaning has changed through the life and relationships accumulated there.

Recognition Between Kanae and Takaki

Kanae’s recognition of Takaki’s estrangement coexists with the happiness she feels near him. After finding him, she sits beside him, glad to be close enough to feel the height of his shoulders. Yet the words “Not here” briefly cross her mind, and her heart stings. The surrounding landscape is vivid and particular: the school lights are tiny in the distance, a wind turbine turns above the town, and gaps in fast-moving clouds reveal the Milky Way and the Summer Triangle. The wind gradually calms her. This setting offers a moment of shared presence, but does not erase the unease she associates with Takaki. Closeness and loneliness remain side by side.

That tension sharpens when Kanae walks with Takaki from the light outside a convenience store toward the shadow around the corner, where their bicycles are parked. Watching his back and feeling the distance between them grow, she reaches out and catches the tail of his shirt. He stops and turns. Kanae shudders, as though she has heard “Not here,” and reads powerful determination in his quiet, unsmiling eyes. The scene does not establish that Takaki speaks the words; it shows how strongly Kanae anticipates them. Her attempt to confess her feelings is bound to a moment of physical hesitation and imagined refusal, so the motif becomes a measure of the distance she feels even while trying to close it.

Places That Hold Feeling

The idea that a place can acquire emotional weight receives its clearest formulation in Takaki’s later thought: “Just living somewhere is enough to make the sadness collect there.” In his apartment, sadness seems to have gathered gradually, like fine dust forming a film before anyone notices. Its evidence is ordinary and specific: one toothbrush remains by the sink, white sheets have been hung up to dry for someone else, and the phone retains its call history. The room’s meaning is not supplied by scenery alone. It is made visible through objects and traces of a life that has taken place there.

Taken together, these episodes complicate the idea that belonging can be secured simply by moving to a new place, returning to an old one, or standing beside someone loved. Tokyo first overwhelms Takaki and later becomes his deliberate destination, yet does not stop feeling strange. Iwafune first signifies homesickness to Akari and later becomes the hometown she is reluctant to leave. For Kanae, the sea’s “not here” becomes a bridge to Takaki’s concealed or perceived alienation, without resolving her own longing for him. The motif therefore treats place as something shaped over time by memory, relationships, and accumulated sadness—and belonging as an experience that can change without ever becoming uncomplicated.
