Shigeru Kimura

Shigeru Kimura’s decisive role is to bring an older generation’s experience and stubborn care into a crisis involving his son, Yuichi Kimura, and grandson, Wataru. He and his wife, Akiko Kimura, act on an unsettling phone call, travel to intercept Yuichi on the train, and face the schoolkid responsible for the danger. Shigeru’s way of confronting the boy joins practical action to a challenge against his faith in being lucky and untouchable: survival, he insists, cannot be assumed in advance.

Family, Work, and the Sense of Danger

Shigeru is Akiko Kimura’s husband and Yuichi Kimura’s father; in the crisis aboard the train, he and Akiko identify themselves as Yuichi’s parents and arrive because their son is in trouble. Their concern extends to Wataru. After Shigeru tells Akiko about what he has heard, she suggests trying to call Yuichi again. Shigeru struggles through the digital telephone’s menu to return the most recent call, but the number is switched off. The failed call offers no clarification, and Shigeru’s worry turns toward Wataru as he imagines possibilities the caller did not specify.

Shigeru describes the call as carrying the smell of bad intent, an expression Akiko recognizes from their shared past. She recalls that he used to speak that way often, as if bad intent were something that haunted him. His intuition is not presented as proof; in this moment it is a warning that sharpens the couple’s unease while the facts remain incomplete. Akiko, meanwhile, continues eating crackers and asks whether he wants to try calling again, an ordinary domestic gesture set against the growing seriousness of his concern.

The Work He Left Behind

In conversation with Akiko, Shigeru revisits why he wanted to leave their old line of work. Akiko remembers one reason: after Yuichi was born, Shigeru wanted to be present as their son grew up and proposed changing careers. She had welcomed the idea because she, too, had wanted a change. Shigeru corrects that account without rejecting it. Yuichi’s birth mattered, but it was not the whole explanation: about thirty years earlier, he had become fed up with the work and with the people around him.

The evidence does not name that former occupation, so its nature remains unstated. What Shigeru does reveal is that the decision to leave had both a family reason and a personal limit. His recollection also connects his present reading of danger with a long-standing habit of noticing what he regards as bad intent. When the crisis reaches him through a phone call, the old sensitivity returns not as a story about his former work, but as a reason to take the threat seriously and move toward his family.

Finding Yuichi on the Train

Shigeru and Akiko rush to catch the train at Mizusawa-Esashi after the phone call. When they meet the schoolkid, Shigeru recognizes him as the caller: he tells the boy that they may be meeting face-to-face for the first time, but the call has already established who he is. The boy’s manner has been mild enough to address Shigeru as a grandfather, yet Shigeru judges that he chooses his words carefully and senses something troubling beneath the politeness.

Akiko is present for the encounter, and the two of them explain their arrival as an overprotective response to their son’s predicament. Shigeru immediately asks where Yuichi is. The question makes the priorities of his intervention plain: the encounter with the boy matters, but first he needs to locate his son. The train setting also makes the meeting a direct consequence of the call. Unable to reach Yuichi by phone, Shigeru and Akiko have come to the person whose message alarmed them.

Confirming Wataru’s Safety

Later, Shigeru uses the digital display above the door at the back of car eight to send a sentence across the train: Wataru is safe. The message moves from right to left where passengers normally see news and train announcements, and it passes five times. Shigeru laughs at the schoolkid’s surprise and asks again whether he is surprised. The repeated statement is both information and an answer to the uncertainty that has been weighing on him. Its public, conspicuous form reverses the boy’s apparent expectation that Shigeru would be unable to act.

The message also confirms what Shigeru most needed to know. His earlier fear had been fed by a call without specifics and by the inability to reach Yuichi; now the display states Wataru’s safety plainly. Shigeru experiences relief as the sentence goes by, but he does not stop at reassurance. He turns the confrontation toward the boy who has treated his own luck as protection from consequences.

Challenging the Schoolkid’s Certainty

Shigeru raises a gun and presses it between the schoolkid’s eyes. In the face of that immediate threat, he argues from the difference between the boy’s short life and his own and Akiko’s more than sixty years. The boy is about fourteen or fifteen, Shigeru says, and cannot know whether he will live another fifty years. Illness or accident could intervene. Shigeru’s point is not that age makes him invulnerable; rather, the boy has no basis for believing that his future is guaranteed.

The schoolkid responds with rage, and Shigeru sharpens the reversal: he and Akiko may have been dismissed as old and used up, but they have more future ahead of them than the boy who thinks himself untouchable. The claim is a taunt delivered at gunpoint, not an assurance about what will happen. It makes the scene’s conflict personal and generational: the child’s confidence in luck meets the hard limit of mortality, while the older couple’s concern for their family has brought them back into danger. Shigeru’s response to the crisis is therefore more than protective travel or a message on a screen; he confronts the boy’s certainty with the one future neither of them can claim to know.
