Loneliness

Loneliness is the central, defining condition of Yozo's existence in No Longer Human, a state of radical isolation that precedes and outlasts every relationship, every attempt at connection, and every form of escape. It is not merely an emotion but a structural feature of his consciousness: a conviction that he alone is fundamentally unlike other human beings, a condition that drives his compulsive clowning, his self-destructive addictions, and his repeated suicide attempts. The novel traces this loneliness from its origins in a childhood of incomprehension and fear through its intensification in adolescence and adulthood, culminating in Yozo's final self-identification as a 'reject'—a man disqualified from the human community. Loneliness in the novel is not a temporary affliction but an inescapable prison, the source of both Yozo's most desperate performances and his most profound suffering.

Origins in Childhood Incomprehension

Yozo's loneliness begins not with rejection but with a fundamental failure to understand the world around him. From his earliest memories, he is baffled by the most ordinary aspects of human life: the purpose of a station bridge, the necessity of eating three meals a day, the sensation of hunger itself. 'Mine has been a life of much shame,' he writes, and that shame is rooted in his inability to grasp what others take for granted. He describes his childhood as a state of perpetual terror, lying awake at night groaning because his 'concept of happiness seemed to be completely at variance with that of everyone else.' This cognitive isolation is compounded by a deep fear of human beings: he sees in the face of an angry person 'a wild animal in its true colors, one more horrible than any lion, crocodile or dragon.' Unable to share the basic assumptions of those around him, Yozo retreats into a private world of dread, convinced that he is 'the only one who is entirely unlike the rest.'

The Clown as a Strategy of Concealment

To survive among people he cannot understand, Yozo invents a persona: the clown. 'This was how I happened to invent my clowning,' he explains, calling it 'the last quest for love I was to direct at human beings.' The clown is a mask designed to hide his true self—a self he considers so defective that its exposure would mean annihilation. He performs tirelessly, making his family laugh with absurd antics, writing comic stories for his teachers, and becoming the class entertainer. But the performance is exhausting and lonely: 'I managed to maintain on the surface a smile which never deserted my lips; this was the accommodation I offered to others, a most precarious achievement performed by me only at the cost of excruciating efforts within.' The clown's success only deepens his isolation, because the laughter he provokes is directed at a fiction, not at the terrified boy behind it. When Takeichi, a classmate, sees through the act and whispers 'You did it on purpose,' Yozo feels 'as if I had seen the world before me burst in an instant into the raging flames of hell.' The exposure of his performance is the ultimate catastrophe, because it threatens to reveal the loneliness he has worked so hard to conceal.

The Impossibility of Friendship

Yozo's loneliness is not alleviated by his relationships; it is confirmed by them. He admits that he has 'not once actually experienced friendship' and that his only 'painful recollections' are of acquaintances. Even his closest companion, Masao Horiki, is a source of degradation rather than connection. Horiki treats Yozo as 'the living corpse of a would-be suicide, a person dead to shame, an idiot ghost,' and Yozo knows it: 'Horiki at heart did not treat me like a full human being.' Yet he cannot break away, because Horiki is the only person who will tolerate him. The loneliness of this friendship is captured in a single image: when Yozo visits Horiki's home and eats a bowl of watery jelly, he feels 'unbearably lonely' as he manipulates the peeling lacquer chopsticks. He is surrounded by people—Horiki, his mother, a woman visitor—but he is utterly alone, a parasite in a world that has no place for him. The novel's epilogue confirms this pattern: the Madam of the Kyobashi bar, who knew Yozo for years, says simply, 'I just kept thinking that when human beings get that way, they're no good for anything.'

Women as Temporary Refuge

Women offer Yozo moments of respite from loneliness, but never a cure. He finds in prostitutes 'absolute security' and 'a natural friendliness which never became oppressive,' and he sleeps soundly in their arms. Yet even this comfort is tinged with isolation: he thinks of prostitutes as 'imbeciles or lunatics,' not as fellow human beings. The women who love him—Tsuneko, Shizuko, Yoshiko—each provide a temporary home, but Yozo remains fundamentally alone within these relationships. He describes his loneliness as something women can 'instinctively sniff out,' and this very perceptiveness becomes another cause of his being 'taken advantage of.' After Yoshiko's violation, Yozo's isolation becomes absolute: he loses even the ability to trust the one person who trusted him completely. His final, desperate cry—'Take me away from Yoshiko'—is a confession that intimacy itself has become unbearable. The novel's most poignant image of loneliness may be the moment when Yozo, recovering from a suicide attempt, murmurs 'I'm going home'—but neither he nor the reader knows what place he means.

The Final Isolation: Madness and Exile

Yozo's loneliness culminates in his confinement to a mental hospital, where his delirious wish for 'a place without women' is grotesquely fulfilled: his ward holds only male lunatics, and the nurses are men. He is no longer a criminal, he reflects, but 'a lunatic'—a label that seals his separation from the human world. Even after his release, he is sent to a remote coastal village, where he lives with an ugly old servant named Tetsu, who occasionally 'violates' him. His father's death, which he learns of in the hospital, 'eviscerates' him: 'He was dead, that familiar, frightening presence who had never left my heart for a split second. I felt as though the vessel of my suffering had become empty, as if nothing could interest me now. I had lost even the ability to suffer.' This is the final stage of Yozo's loneliness: not pain, but emptiness. He concludes his notebooks with the words 'Everything passes,' a truth that offers neither comfort nor connection, only the bleak assurance that even suffering will fade. The novel's epilogue, narrated by an unnamed acquaintance, reports that Yozo has disappeared; no one knows if he is alive or dead. His loneliness has become absolute, a state that persists beyond the boundaries of the text itself.
