Memory and Identity: How Erasure Reveals the Self

The Central Thematic Claim

In If Cats Disappeared from the World, Genki Kawamura argues that personal identity is not a fixed, internal essence but rather a fragile construct woven from our relationships, shared experiences, and the physical objects that anchor our memories. The novel’s central thematic claim is that we do not simply possess memories—our memories possess us, and when the external things that hold those memories are erased, pieces of our identity vanish with them.

The narrator, a thirty-year-old postman diagnosed with a terminal brain tumor, initially believes he can trade away parts of the world without losing himself. Through the devil Aloha’s bargain—erase one thing from existence, gain one extra day of life—he discovers the opposite: each erasure strips away another layer of who he is. The novel traces this unraveling through the sequential disappearance of phones, movies, and the threatened loss of cats, culminating in the narrator’s recognition that to preserve his core identity, he must accept mortality rather than continue erasing the world that made him.

Memory as the Foundation of Self

Before the bargain begins, the narrator already lives a life of diminished memory and connection. His role as a postman—handling thousands of letters but forming no lasting bonds—mirrors his internal state. He has become estranged from his father, lost his mother four years earlier, and allows his mobile phone to do what his own mind once did. The evidence chapter from Tuesday makes this explicit: “I had left the work of memory and even my ties to other human beings to my mobile phone.” This confession reveals that even before Aloha arrives, the narrator has outsourced a fundamental human capacity. He cannot recall phone numbers, addresses, or the small details that constitute intimacy.

When forced to make one final call before phones disappear, he discovers only one number stored in his actual memory: that of his ex-girlfriend. This moment crystallizes the novel’s thesis. True memory—the kind embedded in the self rather than a device—attaches only to relationships that genuinely mattered. The hundreds of contacts in his phone represent shallow connections; the one number he remembers by heart represents love, loss, and unfinished emotional business. Identity, Kawamura suggests, is not the sum of all our interactions but the residue of our deepest attachments.

Tracing the Theme Across Three Acts of Erasure

Act One: The Disappearance of Phones (Tuesday)

The erasure of mobile phones functions as more than a technological subtraction—it forces the narrator to confront how much of his relational memory he has surrendered to a device. Without his phone, he cannot confirm meeting times, scroll through old messages, or avoid the awkwardness of genuine presence. He arrives an hour early at the clock tower, a mistake he would never have made with digital assistance.

More significantly, his reunion with his ex-girlfriend becomes an exercise in exposure. She recalls details about him that he has forgotten: his frequent bathroom breaks, his constant sighing, his inability to handle alcohol. These small, unflattering memories belong to her, not him. She holds a version of his identity that he cannot access independently. The novel suggests that identity is distributed across the minds of others—we are, in part, whatever others remember about us. When she asks him to guess her favorite food, animal, and drink, he fails repeatedly. His memory of her has been deliberately suppressed, and with that suppression, a portion of his own history has been lost.

The Buenos Aires trip emerges as the pivotal memory that fractured their relationship. A fellow traveler died, and the narrator’s response—or lack thereof—created a rift that neither could repair. His inability to remember exactly why they broke up demonstrates how people “forget things in order to build new memories,” yet this adaptive forgetting also hollows out the self. The narrator cannot understand who he is because he cannot accurately recall who he was.

Act Two: The Disappearance of Movies (Wednesday)

When movies vanish, the narrator loses not just entertainment but a repository of formative experience. His childhood memory of seeing E.T. with both parents, his mother’s love of Chaplin, the films watched with his ex-girlfriend at the same theater he now collapses in front of—all these are anchored to cinema. Movies are shared memory-objects. They mark periods of life, preserve emotional states, and connect people across time.

The narrator’s choice to watch a blank screen during his final viewing is telling. Rather than selecting a specific film, he projects his own life onto the emptiness. Memories of his mother’s death, his estranged father, and his former relationship play out as an internal movie. This act reveals that the most important narratives are the ones we carry within us, but it also shows how dependent those internal narratives are on external triggers. Without films to catalyze recollection, whole swaths of emotional memory risk going dormant.

His ex-girlfriend’s question—why she rewinds sad movies—receives the correct answer: she hopes for a happier ending. This detail connects to the broader theme of identity as something we constantly revise. We rewind our memories hoping to find better outcomes, to reconstruct a self we can accept. The disappearance of movies threatens this process of revision and reconciliation.

Act Three: The Threatened Disappearance of Cats (Friday)

The devil’s demand to erase cats brings the theme to its crisis point. Unlike phones or movies, cats are living beings with whom the narrator has shared genuine emotional bonds. Lettuce, the cat of his childhood, died on his mother’s lap—a memory so vivid it returns in Chapter 5 with excruciating detail: “His small body trembled as he let out a painful meow.” Cabbage, his current cat, has been his companion through four years of solitude following his mother’s death. To erase cats would be to erase these beings and, by extension, the memories and love they embody.

The narrator’s mother understood this connection implicitly. She told him, “Cats and humans have been partners for over ten thousand years. One thing you realize when you’ve lived with a cat for a long time is that you may think that you own them, but that’s not really the way it is. Cats simply allow us the pleasure of their company.” This insight reframes the relationship: cats are not possessions but co-inhabitants of memory. They witness our lives, absorb our grief, and anchor our sense of home.

When Cabbage speaks, offering to sacrifice himself—“For you, sir, I would gladly disappear”—the narrator faces the ultimate test of identity. Accepting this offer would mean surviving at the cost of everything that makes survival meaningful. His refusal marks the thematic climax: he would rather die as the person shaped by these relationships than live as someone who erased them.

Character Connections to Memory and Identity

The Narrator

The narrator begins as a man who has systematically avoided deep identity formation. His job requires no creativity, his apartment holds few personal artifacts, and his emotional life is attenuated. Through the progressive erasures, he discovers that identity is not a private possession but a shared construction. His ex-girlfriend holds memories of him that he has lost; his mother’s letter reveals qualities he never recognized in himself; his father’s stamp collection connects him to a relationship he has denied.

Aloha, the Devil

Aloha reveals himself in Chapter 6 as “the person you could have been”—“the side of yourself that you’ve never shown to the world.” He embodies the narrator’s unlived possibilities: cheerful, impulsive, free from worry about others’ opinions. This revelation adds complexity to the memory-and-identity theme by suggesting that identity includes not only what we remember but also what we regret. Aloha is a walking repository of roads not taken, and his disappearance at the novel’s end signals the narrator’s acceptance of his actual, imperfect self.

The Ex-Girlfriend

The ex-girlfriend functions as an external hard drive of the narrator’s memory. She remembers his bathroom habits, his sighs, his drinking limitations—the texture of daily life that he has forgotten. She also holds the traumatic memory of Buenos Aires and the gradual dissolution of their relationship. Her role demonstrates that identity is not self-contained; it lives in the minds of those who have known us intimately. When she gives him “homework” to guess her favorite place, she is testing whether he can access the shared memory that once defined them.

The Mother

The mother is the novel’s most powerful memory-figure. Even after death, she shapes the narrator’s identity through the letter she left behind, which lists ten wonderful qualities about him rather than her own desires. Her “magic trick” for dispelling sadness—closing one’s eyes, forcing a smile, then opening them to find the sadness transformed—becomes a recovered memory that literally saves the narrator. When he whispers “Thanks, Mom” for the first time, he reclaims a piece of identity that grief had buried.

The Father

The father represents repressed memory and the identity-wounds that come from unresolved relationships. The narrator has not spoken to him since the day he refused his father’s outstretched hand. Yet the father’s stamp collection, the postcards with a cat resembling Lettuce, and the memory of a firm hand in a movie theater all resurface as the narrator prepares for death. Recovering these memories allows him to reconstruct an identity that includes filial connection, and his final act—writing a letter and then delivering it in person—is an act of identity reclamation.

Symbolic Anchors of Memory

The Wristwatch

The wristwatch belongs to the mother, who asked the father to fix it before she died. He arrived too late with the still-broken watch, and this failure crystallized the narrator’s estrangement. The watch symbolizes time stopped at the moment of loss—a memory frozen in grief. Until the narrator can re-engage with this symbol, forgiving his father’s imperfection, his identity remains stuck.

Cabbage the Cat

Cabbage is the living embodiment of the narrator’s connection to his mother and to the past. When Cabbage forgets the mother entirely—“I don’t recall a thing”—the narrator feels the pain of erasure even before any supernatural disappearance. The photo album he retrieves from the closet represents his desperate attempt to preserve shared memory through physical objects. Cabbage’s survival, and the narrator’s choice to entrust him to his father, represents the transmission of memory across generations.

The Stamp Collection

The stamp collection discovered in Chapter 6 triggers a flood of childhood memories involving the father. Stamps from foreign countries, postcards with cat illustrations—these objects are memory-triggers that reconnect the narrator to a relationship he has denied. The collection explains, retroactively, why he became a postman: he was always seeking connection through the mail, following his father’s silent example.

The Postman Uniform

When the narrator dons his postman uniform for the final journey, he acknowledges that he has become his father’s “spitting image.” The uniform symbolizes identity as both inherited and chosen. He is a postman because of his father’s stamps, yet he has made the role his own. Wearing it while delivering his letter in person transforms him from a passive carrier of others’ messages into an active communicator of his own truth.

Complexity and Contradiction

Kawamura does not present a simple equation where more memory equals stronger identity. The novel acknowledges that forgetting serves a purpose. The narrator notes that “people forget things in order to build new memories. You have to forget some things in order to move on in life.” This adaptive forgetting allows survival after trauma. After his mother’s death, after the breakup, the narrator’s emotional numbing was a defense mechanism. The problem arises not from forgetting per se but from forgetting that severs essential connections.

The novel also complicates the idea that identity is purely relational. Aloha—the unlived self—suggests that identity includes potential selves, the people we might have become. The narrator’s acceptance of his actual life, with all its regrets, is not resignation but wisdom. As Aloha tells him before departing, “There’s a certain beauty in those regrets. They’re proof of having lived.” Identity, then, is not about perfect memory or maximal experience but about owning the particular shape of one’s existence, losses included.

The mother’s letter introduces another layer: identity as gift. Her ten items do not describe what she wanted from life but what she saw in her son. She gave him an identity—kind, persistent, observant—that he had not recognized in himself. This suggests that memory is not only retrospective but constitutive; what others remember about us helps create who we become.

Finally, the narrator’s decision to reject the final bargain and die rather than erase cats resolves the central contradiction of the novel. He has been gaining days of life by making things disappear, but each gained day has made him less himself. The bargain was always a trap: survival through erasure is not survival at all. By choosing death, he paradoxically reclaims his identity in full.

Study Questions and Answers

1. How does the disappearance of phones in Chapter 2 reveal the narrator’s reliance on external objects for memory and identity?

When phones vanish, the narrator realizes he has memorized only his ex-girlfriend’s number out of hundreds of contacts. His admission that he “left the work of memory and even my ties to other human beings to my mobile phone” shows that he has outsourced not just information storage but relational connection itself. Without the device, he cannot access the shallow network of acquaintances stored in it, revealing that his social identity was largely technological rather than genuinely internal. The one number he remembers by heart points to the one relationship that truly shaped him.

2. What does Aloha’s revelation in Chapter 6 add to the novel’s treatment of identity?

When Aloha explains he is “the person you could have been”—“the side of yourself that you’ve never shown to the world”—the novel suggests that identity encompasses not only lived experience but also unlived potential. The cheerful, impulsive Aloha embodies the narrator’s regrets and alternate paths. This complicates the memory-identity theme by proposing that we are shaped just as much by the choices we rejected as by those we made. The narrator’s final acceptance of his actual life, regrets included, represents a mature integration of identity.

3. Why is the narrator’s refusal to erase cats the thematic climax of the novel?

Erasing cats would mean erasing Lettuce, who died on the narrator’s mother’s lap, and Cabbage, who has been his companion through four years of grief. These beings are not abstract commodities but living presences who hold and witness his most significant memories. The narrator’s mother taught him that cats are partners, not possessions, and his refusal to trade their lives for his own demonstrates that he finally understands: a life preserved by destroying what makes it meaningful is no life at all. This choice restores his moral identity.

4. How do the mother’s letter and her “magic trick” function as recovered memories that reshape the narrator’s identity?

The mother’s letter lists ten wonderful qualities about her son rather than her own desires, giving him an identity he had not seen in himself. Her postscript—“Please make up with your father”—offers a directive that reorients his final actions. The magic trick, remembered through Cabbage’s prompting, provides a practical method for transforming sadness: close your eyes, force a smile, and let the inner darkness give way to light. Recovering this childhood memory equips the narrator to face death with emotional resources his mother planted long ago.

5. In what way does the narrator’s decision to deliver his letter in person, wearing his postman uniform, represent a resolution of his identity crisis?

By donning the uniform and bicycling to his father’s house, the narrator acknowledges that he has become his father’s “spitting image” and that his vocation as a postman—silently carrying messages between people—mirrored his father’s emotional distance. Delivering the letter in person transforms him from a passive carrier into an active communicator. He refuses to repeat the mistake of his youth, when he rejected his father’s outstretched hand. This act integrates his inherited identity (son, postman), his chosen identity (letter-writer, Cabbage’s caretaker), and his reclaimed memories into a coherent self, even at the threshold of death.

Conclusion

If Cats Disappeared from the World ultimately argues that identity is not a possession but a practice—something maintained through memory, relationship, and the courage to face loss without erasing it. The narrator begins believing he can trade away pieces of the world and remain intact. He ends by recognizing that “there’s a reason why everything exists in this world. And there’s no reason good enough for making them disappear.” Memory and identity are not separate from the objects, beings, and places that anchor them. To preserve the self, we must preserve the world that remembers us back.
