Shigeru Kimura–Wataru grandfather–grandson relationship

Shigeru Kimura’s bond with his grandson Wataru is expressed most clearly as protective attention: Wataru’s safety matters enough to redirect the older couple’s focus toward a danger they had not considered. The relationship also carries a contrast between generations. Shigeru and Akiko remember being feared in the past, while their recent life has included doting on Wataru; the prospect that someone might use the grandson to settle an old score turns that family affection into immediate vigilance.

Family Affection and Concern

When Akiko raises the possibility that someone from the past might bear a grudge against them and take revenge on Wataru, Shigeru stops in the middle of what he is doing. He admits that the possibility had not occurred to him. The pause makes the concern consequential: Wataru is not an abstract family tie but someone whose safety can abruptly alter Shigeru’s attention and priorities.

Before the suggestion, Shigeru had reasoned that Wataru was in the hospital and that he could think of no particular reason the boy would be in danger there. Akiko’s proposal does not establish that an attack is planned; it introduces a feared possibility. Their response reveals the tension between the apparent security of the hospital and the older couple’s awareness that unresolved history could reach into Wataru’s life.

Shigeru links this protectiveness to the change in their family life, acknowledging that he and Akiko have spent the past few years doting on Wataru. The remark places their affection against the more dangerous identities they associate with their earlier lives. Concern for their grandson does not erase that past; it gives the old capacity for danger a new object of protection.

A Grandson Between Past and Present

Akiko’s theory is that someone who feared the couple thirty years earlier might now see their age as an opportunity to strike at Wataru. Her reasoning makes the generational relationship part of a wider conflict: the possible danger comes not from anything Wataru has done, but from hostility directed at his grandparents. He could become the target through his place in the family.

Shigeru rejects the assumption that the passage of time has made the couple harmless. He insists that they remain as dangerous as before, even as he acknowledges how much they now indulge their grandson. The contrast defines his protective stance: age and tenderness have not, in his view, taken away the ability to defend Wataru. The scene presents his attachment not as passive worry alone, but as concern joined to confidence in action.

News of Wataru

The family’s anxiety is eventually answered by news received aboard the Shinkansen. A call confirms that Wataru has awakened and is safe. Shigeru tells Akiko that their grandson is all right; her jubilant reaction registers the force of the relief after the possibility of danger had unsettled them. The news changes the immediate emotional stakes without making the earlier concern foolish: the couple had no confirmed threat, but they had no assurance of Wataru’s safety either.

The report comes through a friend whom Yuichi Kimura had asked to check on Wataru. Shigeru’s gratitude for that help underscores the practical side of family care: protecting Wataru depends not only on the grandparents’ resolve but also on trusted people acting on the family’s behalf. The confirmed awakening gives the relationship a concrete resolution in this scene. Wataru is no longer only the absent grandson whose vulnerability they fear; he is safe, and the news allows Shigeru and Akiko to turn from apprehension to relief.
