Kurumizawa’s disappearance in the apartment building

Kurumizawa’s disappearance in the apartment building is a baffling vanishing from an ordinary Sunday morning: after visiting his mother, Kurumizawa disappears somewhere between the twenty-fourth and twenty-sixth floors of his building, leaving his wife waiting with breakfast and no explanation. The event turns a routine domestic errand into a mystery whose precise details seem to rule out an ordinary decision to leave.

Background and the Sunday Call

Ten days after the disappearance, Kurumizawa’s wife recounts that her mother-in-law called at ten on Sunday morning, September 3. She was having trouble breathing, felt dizzy, and could not stand. Kurumizawa dressed quickly and went down to his mother’s apartment, saying he would not be long and asking his wife to prepare breakfast. The date, time, and circumstances are carefully established through her recollection, making the call the last known reason for his departure.

Rain had been falling hard since dawn, so Kurumizawa had canceled his planned round of golf. His wife recognizes that imagining the disappearance would not have happened if it had not rained is only second-guessing, but the canceled plan fixes the morning’s counterfactual in her account. His clothes are described in detail: a dark gray short-sleeved polo shirt, cream-colored chinos, metal-framed Armani glasses, and gray New Balance shoes. He had no socks on and had not shaved before leaving. These particulars create a concrete record of the man who set out for a brief visit, not someone prepared for a journey away from home.

The Unanswered Breakfast

Twenty-five minutes after leaving, Kurumizawa called his wife. His mother had settled down, he said, and he was on his way upstairs. He told her he was hungry and asked her to have breakfast ready when he got back. His wife began cooking pancakes and bacon and warmed the maple syrup, following the Sunday routine: when Kurumizawa did not play golf, he ate a large breakfast of pancakes with crisp bacon. The meal becomes an unfinished expectation, its ordinary preparation continuing after the person it is for has vanished.

When Kurumizawa did not arrive, his wife called his mother, who told her that he had left long before. The mother could confirm that he departed, but the return journey had no witness or known endpoint. His wife places the disappearance somewhere between the twenty-fourth and twenty-sixth floors. That narrow span gives the case its defining puzzle: he had made it into the building and was expected upstairs, yet did not reach his apartment.

Why His Wife Rejects Flight

Kurumizawa’s wife contacted the police when he had not returned by one o’clock. A patrolman came to the apartment, but, seeing no apparent sign of a violent crime, did little beyond advising her to file a missing-person report at the precinct if Kurumizawa had not returned in two days. The police treated a voluntary departure as possible, suggesting that he might have left on impulse because he was dissatisfied with his life.

His wife insists that this explanation does not fit the evidence she has. Kurumizawa went to his mother’s apartment without a wallet, driver’s license, credit cards, or watch. He had not shaved, and he had just called home to request pancakes. To her, these details make an intentional disappearance at odds with the practical circumstances of his departure. The breakfast request is especially difficult to reconcile with the police’s theory: he had arranged to come home, and his wife had prepared for him to do so.

The Stairwell and the Investigation

Kurumizawa never uses the elevator because he dislikes being confined in a small space. Although the couple lives on the twenty-sixth floor, he ordinarily takes the stairs, regarding the climb as exercise that might help control his weight. His usual route therefore passes through the same upper floors where his wife says he disappeared. The stairwell is not presented as a chosen escape route; it is the familiar passage he used to get home.

The wife asks a volunteer investigator to take the case. He asks whether Kurumizawa used the stairs, then agrees to investigate and requests that she take him to the building to see the last place she saw her husband. The case is thus framed around a sharply bounded physical setting and a small set of verifiable details: the mother’s call, Kurumizawa’s visit, his return call, the cold breakfast, and the unexplained gap in the stairwell. The disappearance remains unresolved at this point, but the investigator’s decision shifts the event from a private loss into an active inquiry.
