Nagasawa’s system of living

Nagasawa’s system of living is a deliberate ethic of self-direction: he intends to pursue what he wants, use his abilities to the limit, and postpone reconsideration until circumstances force it. Its apparent strength is also its central contradiction. Nagasawa presents independence from other people’s judgments as discipline, yet his relationships show that a private code does not prevent others from being hurt by the choices made under it.

Principles and ambition

Nagasawa begins from the premise that the world is inherently unfair and that he did not make its rules. Rather than treating unfairness as a reason for resignation, he regards it as an opportunity: an unfair society, he argues, makes it possible to exploit one’s abilities to the limit. He says he will give life everything, go as far as he can, take what he wants, and leave what he does not want, reconsidering only if things go badly. The philosophy is active rather than passive; he insists that he works hard, even while recognizing the self-centeredness of his outlook.

That claim to effort distinguishes his system from simply waiting for advantage to arrive. Nagasawa tells Toru that he is working much harder than Toru is, and Toru concedes that this may be true. Nagasawa also criticizes people who complain while doing nothing. His self-interest is therefore joined to a belief in exertion: the individual should act, develop capacity, and make use of the possibilities an unfair world leaves open.

Desire, discipline, and responsibility

Nagasawa applies the same logic to his relationship with Hatsumi. He says he has never deceived her about his character and that she can leave if she can no longer accept him. He describes sleeping with other women as a game, saying the encounters are brief and impersonal, and claims that nobody is hurt. Hatsumi directly challenges that conclusion: she is hurt, and what she cannot stand is his arrogance rather than the infidelity alone.

His response makes the system’s limits visible. Nagasawa says his behavior does not mean that Hatsumi is insufficient; he describes it instead as an inner hunger and insists that it is part of what makes him who he is. He apologizes for hurting her, but does not present the apology as a reason to change. His identity becomes both explanation and defense: the appetite is not, in his account, a choice he can set aside, but a defining feature he can only live with.

He also distinguishes his conduct from ordinary emotional vulnerability by describing himself as trained to minimize pain. The comparison he makes is to a rat choosing the least painful route after repeated shocks. Hatsumi answers that rats do not fall in love, challenging the reduction of emotional life to a calculation of discomfort. The exchange brings out a tension at the heart of Nagasawa’s discipline: avoiding or limiting hurt may be a strategy, but it does not establish that love and responsibility can be treated as irrelevant.

Toru, Hatsumi, and competing accounts of connection

Nagasawa draws Toru into his argument by claiming that the two men are fundamentally alike: both, he says, are interested chiefly in themselves and can think apart from other people. The difference, as Nagasawa describes it, is that he accepts this self-centeredness while Toru has not recognized it and therefore hesitates and feels hurt. His account offers Toru a place inside Nagasawa’s system, but Toru does not simply accept the identification.

Nagasawa further claims that neither he nor Toru cares whether others understand them, and that self and others remain separate. When Hatsumi asks Toru directly, Toru rejects the idea that he is that strong. He says there are people he wants both to understand and to be understood by; beyond that small circle, he feels the prospects are nearly hopeless, but that does not mean he agrees with Nagasawa. Their disagreement is not merely over whether social approval matters. Toru maintains that particular relationships make understanding important, whereas Nagasawa treats separation as a general principle.

Nagasawa attempts to absorb the difference into his own argument, comparing it to a late breakfast and an early lunch: different names for the same time and food. He then tells Hatsumi that people understand one another when the time is right, not because one person wants to be understood. Yet when Hatsumi asks whether it is a mistake to want understanding from him, he says it is not, and describes such a desire as what most people would call love. He maintains that his system for living differs from other people’s systems. The conversation leaves a gap between recognizing another person’s wish for connection and answering it with reciprocal commitment.

The philosophy under pressure

The dinner conversation makes the system legible through opposing interpretations rather than through a settled verdict. Nagasawa presents self-command, effort, and independence as grounds for living decisively. Hatsumi presses the interpersonal cost: his actions affect her even when he names them a game, and his account of himself does not erase that harm. Toru, meanwhile, refuses Nagasawa’s claim that emotional independence makes them alike, preserving the importance of being understood by specific people.

The system’s force lies in its refusal to let fear or unfairness dictate inaction; its weakness lies in treating personal limits and other people’s pain as matters the individual may acknowledge without allowing them to change course. Nagasawa can say he is sorry and still insist that his appetite defines him. He can recognize love as a desire for understanding while maintaining a way of life that does not promise to meet that desire. The novel thus presents his philosophy not as a general solution to life’s unfairness, but as a sharply individualized code whose consequences become clearest in the relationships it cannot make mutual.
