The Stamp Collection: A Silent Language of Love and Reconciliation

Introduction

The stamp collection in Genki Kawamura’s If Cats Disappeared from the World is far more than a childhood hobby. Tucked away in an old cookie tin, it becomes the linchpin of the narrator’s final hours—a tangible link to his estranged father and the catalyst that transforms a dying man’s regret into a deliberate act of reconnection. While the novel brims with items that the devil forces the narrator to erase, the stamps offer a counterpoint: they are not things to be discarded, but treasures that resurface to restore what has been lost.

What Is the Stamp Collection?

The stamp collection is a set of hundreds of stamps from around the world, kept in a repurposed cookie container that the narrator had used as a “box of treasures” as a child. The collection was built largely through gifts from his father. During his elementary school years, his father traveled to Europe and sent postcards from each destination, each bearing a colorful foreign stamp. The narrator would soak the stamps off the postcards and add them to his collection, preserving them as small, delicate mementos of faraway places. One stamp in particular—a picture of a yawning cat that looked like the family pet, Lettuce—stands out in his memory and later becomes the final stamp he affixes to his goodbye letter.

Physically, the stamps are fragile bits of paper, but for the narrator they carry the weight of an entire relationship. As he rediscovers them, he notes that “the stamp collection became very precious to me” and that he would spend ages “imagining all the different countries they’d come from.”

Where the Stamp Collection Appears

The stamps emerge in two pivotal chapters. In Chapter 6, on Saturday, after the narrator has refused to erase cats and accepted his own impending death, he cleans his apartment and prepares for his funeral. During this process, he comes across the old cookie tin. Despite his conviction that whatever is inside “I probably wouldn’t consider treasure anymore,” he hesitates before opening it. When he finally lifts the lid, he finds his childhood stamp collection and unleashes a flood of memories about his father. These memories include the postcards, the yawning-cat stamp, and the quiet way his father would hand him gifts without speaking.

The stamps reappear in Chapter 7, Sunday, when the narrator finishes writing a long letter to his father. He deliberately picks out the yawning-cat stamp from his treasure box and affixes it to the envelope. But standing before a red mailbox, he realizes that mailing the letter is not enough. He returns to the apartment, puts on his postman uniform, and cycles toward his father’s town, determined to deliver the letter in person. The stamp thus becomes not only a seal on his written words but also the final emblem of a chosen, embodied reconciliation.

How the Meaning of the Stamps Evolves

As a child, the stamps represented adventure and a silent bond. The narrator’s father was “so shy and reserved that he rarely spoke” when giving gifts, so the stamps became a way to communicate. The narrator “understood what was on his mind depending on what kind of stamps he gave me.” They were a private language through which a distant father could say, I am thinking of you. The act of receiving a postcard and imagining its journey—from a Parisian shop to the family mailbox—also sowed the seed that later made the narrator a postman. He explicitly states, “it finally dawned on me why I ended up being a postman.”

When he rediscovers the collection as an adult facing death, the stamps take on a different meaning. They are no longer simply childhood treasures; they are proof that seemingly small objects can hold the weight of an entire world. The narrator reflects, “all these individual things make up an entire world.” The stamps, with their images of festivals, horses, doves, and oceans, embody the thousands of unspoken words between father and son. They prompt him to see mailing a letter as a profound act: “Placing a stamp on an envelope … arriving at its destination … what joy it could bring.” This insight pushes him to write a letter and, in doing so, to reclaim the connection his mother had always wanted him to repair.

The final evolution occurs when he places the yawning-cat stamp on the envelope. That stamp, once a source of childhood laughter, now becomes a deliberate choice—a personal symbol that ties together his mother’s deathbed wish, his father’s quiet love, and his own acceptance of mortality. By choosing not to drop the letter in the mailbox but to deliver it in person, he transforms the stamp from a token of distance into a ticket for reunion. The stamps, once used to send words across oceans, now fuel a bicycle ride across the bay.

Character and Theme Connections

The stamp collection weaves together the novel’s central characters and themes.

• The Narrator: The stamps explain his very profession. Seeing them again clarifies why he became a postman—a role that, ironically, he had never fully understood. The rediscovery also spurs his final meaningful action. Read more about the narrator.
• The Father: A man who expressed himself through objects rather than words, the father gave stamps as silent offerings. The collection is his legacy, invisible until the moment his son is ready to see it. More on the father.
• The Mother: Though she does not directly handle the stamps, her influence permeates this object. Her postscript in the letter from Chapter 5—“Please make up with your father”—hangs over the narrator’s discovery. The stamps serve as the instrument to fulfill her final wish. See the mother.
• Cabbage: The cat, as silent witness, stays by the narrator’s side as he opens the cookie tin and writes the letter. His presence underscores the family ties that the stamps represent. See Cabbage.

Thematically, the stamps touch nearly every major idea in the novel:

• Memory and Identity: The stamps unlock suppressed memories of the father and reshape the narrator’s understanding of his own life choices. They answer the question of why he spent his days delivering letters.
• Family Estrangement and Reconciliation: The collection is the bridge across years of silence. Without it, the narrator might never have written the letter or pedaled to his father’s house.
• Mortality and Acceptance: He finds the stamps while arranging his own funeral and throwing away useless belongings. This timing forces him to confront what truly mattered in his life.
• Love and Sacrifice: The stamps echo the mother’s sacrifice—she planned a family trip to reconcile father and son—and the narrator’s own sacrifice in refusing to erase cats. That refusal opened the emotional space for him to reconnect with his father through the stamps.
• Trade-offs and the Cost of Existence: Unlike the items the devil erased, the stamps illustrate what is lost when we let precious connections disappear. The narrator nearly threw the tin away as a meaningless old object; instead, he found a part of himself.

Study Questions and Answers

1. What is the literal story behind the stamp collection, and how did the narrator acquire it?
   The collection began when the narrator’s father gave him Olympic commemorative stamps as a child. Over time, the father brought additional stamps from his travels, including postcards mailed from Europe. The narrator soaked off the stamps and stored hundreds of them in a cookie tin. A particular stamp featuring a yawning cat that resembled Lettuce became a favorite.

2. How does rediscovering the stamps change the narrator’s understanding of his own career?
   As the narrator handles the stamps, he recalls staying awake at night imagining the journey of each postcard—from the mailbox to the plane to his doorstep. In that moment, he realizes that the excitement and wonder he felt as a child planted the seed for his adult job as a postman. The stamps make him see his work not as mere labor but as a connection to a deeper, lifelong fascination with delivering messages.

3. Why does the narrator choose the yawning-cat stamp for his final letter, and what does this choice signify?
   The yawning-cat stamp is the one he remembers laughing at as a child because it looked exactly like the family cat, Lettuce. Selecting it for the letter to his father is an act loaded with personal history—it links the father’s rare gesture of humor, the memory of Lettuce dying on the mother’s lap, and the narrator’s own bond with Cabbage. It signals that he is deliberately using a symbol from their shared past to heal the rift.

4. What role does the stamp collection play in the narrator’s reconciliation with his father?
   The collection acts as a catalyst. Simply finding the stamps unleashes memories that compel the narrator to write the long-postponed letter. The act of selecting a stamp, putting on his postman uniform, and cycling to his father’s house transforms a static memory into a living gesture. The stamps provide both the emotional realization and the practical means—the final stamp on the envelope—to deliver not just words but his actual presence.
