The apartment building where the narrator and Kei live

The apartment building where the narrator and Kei live is a seven-story residence facing Tokyo Route 8, where the incessant traffic and the building’s nighttime emptiness make ordinary urban life feel strangely divided. It first appears as the narrator’s home after his divorce, a place whose daily patterns he observes from the windows and hallways. Later, apartment 305 becomes central to his relationship with Kei and to Mamiya’s growing suspicion that the woman accompanying the narrator is not simply another tenant. The building is both a practical setting for their encounters and a threshold where familiar rooms and routines begin to give way to the uncanny.

Setting and Daily Conditions

The building stands directly beside Tokyo Route 8, a busy road where traffic continues through the night. When the narrator first moved in full time, long-haul trucks passing around midnight kept him awake. A traffic light roughly a hundred meters away repeatedly interrupted their passage, but each pause only made the returning noise more conspicuous. He experienced the rumble as physically oppressive, and for a time it made him bolt upright, short of breath. After about ten days, he grew accustomed to the round-the-clock traffic.

That adjustment gives the building two distinct kinds of quiet. Its exterior is exposed to a seemingly unceasing roar, yet, three weeks into his renewed bachelorhood, the narrator notices that the interior is unusually still. He opens the curtains but leaves the window closed, knowing that it would admit the heat, fumes, and traffic noise. From above, he sees an otherwise empty parking lot with a single pink van left behind. Three smiling squirrels are painted on its side, and the van belongs to a children’s-apparel company. The contrast between this small, recognizable detail and the broad asphalt emptiness makes the building’s apparent abandonment feel concrete rather than merely atmospheric.

The Building by Day and Night

The narrator tests his impression by looking at the building’s southeast face, where every apartment has at least one window. After eleven at night, his own window on the seventh floor is the only one showing a light. He considers whether residents might simply have gone to bed, but concludes that this cannot explain the darkness across nearly all the other units. The building’s silence is therefore not just an impression created by the traffic outside: at that hour, the narrator appears to be its only resident awake, with Kei the other person who remains there on some nights.

Kei later tells the narrator that, by around this time on most nights, the two of them are the only people left in the building. Her disclosure unsettles him because it makes their isolation mutual and explicit. His first response is to conceal his reaction, while her willingness to say it underscores how unusual their shared nighttime circumstances are. The building’s emptiness also contrasts with its daytime return to activity. In the morning, footsteps click across concrete floors; doors close, telephones ring, and voices gradually fill the space. Office staff in the neighboring apartment begin their work, and the accumulating sounds carry the narrator toward midday. The shift is not a change of address but a recurring change of social presence: the same building that seems deserted after dark resumes ordinary collective life by day.

Apartment 305 and Kei

Kei’s apartment is number 305, beside a large three-bedroom unit at the end of the hall. From outside, the narrator had assumed that 305 was one of the building’s small, single-room apartments with a tiny kitchen-dinette. He reflects that even such a modest unit would be expensive in this part of Tokyo, and wonders whether Kei’s parents, who live in a distant farming village, help her financially. He also speculates that she could conceal some facts of her life from them, though he admits that he does not know what they know. These thoughts place Kei’s private life inside the building’s ordinary domestic geography without establishing answers the narrator does not possess.

Kei lets him enter 305 and tells him that the air conditioner will take time to cool the room. Their exchange is casual, but the apartment becomes more than a neighbor’s private interior: it is where the narrator’s closeness to her is visible to others and where the building’s history presses into the present. On another occasion, Mamiya recalls seeing the narrator at his apartment door with a woman. Because the door was open only a narrow crack and the woman blocked it, Mamiya says he nevertheless seemed able to see into the apartment as if he could see through her. His recollection turns a familiar threshold into evidence that his perception of the woman does not fit an ordinary encounter.

The Manager’s Account and the Building’s Significance

Mamiya’s suspicion deepens after he sees the narrator looking unexpectedly healthy one day after having appeared severely emaciated. Near the building entrance, he speaks to a man pruning shrubs and learns that the man is the building manager. The manager recognizes the woman with the narrator as resembling the woman who had lived in 305 and died by suicide. The apartment had been remodeled and rented to a health-food company for its Tokyo office. This history gives the apparently ordinary unit a past that the narrator has not acknowledged and that Mamiya is trying to understand.

Mamiya and the manager later follow the narrator and the woman to the third floor. They see the woman unlock 305 and the narrator about to enter. When they hurry to the door, a young man answers and denies that anyone else has gone inside. He allows them to search the small office, including its toilet and bath, but they find no trace of the pair. The sequence makes the building’s rooms and corridors part of a dispute between direct observation and what can be verified afterward. The manager can identify the woman by her resemblance to the former tenant; Mamiya witnesses her with the narrator; yet the room is empty when they enter.

The building’s final threshold moment comes when Mamiya, standing at the open apartment door, sees Kei by the elevator. The narrator ignores Mamiya’s warning and steps into the hallway, where Kei stands some ten meters away in a white, sleeveless housedress reaching nearly to her ankles. The ordinary distance between apartment door and elevator becomes the setting for a recognition that Mamiya cannot prevent. Across these episodes, the building’s nighttime vacancy, daytime office routines, numbered apartments, and shared hallways establish a sharply material setting for encounters that resist explanation. Its urban anonymity makes the narrator and Kei’s companionship possible, while the history attached to 305 unsettles the boundary between a lived-in home and a place inhabited by memory.
