Shōko and Eriko arrive in Hakone for a trip that Eriko has planned. To endure it, Shōko mentally detaches, treating Eriko less like a person and more like an object. At a soba restaurant, Eriko meticulously photographs her own untouched meal for the blog, as Shōko has already eaten most of hers. When they discuss a TV show, Eriko criticizes Shōko’s taste, stating she cannot enjoy anything she cannot relate to. Eriko then launches into a monologue comparing the societal pressure on women to compete with one another to invasive species in an ecosystem. She proposes that she and Shōko become an “invincible duo” (274) to fight this system.
At their hotel, Shōko lies about having her period to avoid sharing the public bath. Unfazed, Eriko pressures her by offering tampons until Shōko relents. In the empty bath, Eriko reveals that she adores her strict but supportive parents before she begins swimming naked, thereby breaking bathing etiquette and horrifying Shōko, who concludes that Eriko is deeply immature and behaves like a child. As she sits curled in a corner, feeling her own identity weaken, Shōko finds herself trapped in a deeply uncomfortable and bizarre situation.
Lying awake in the hotel room, Eriko reflects on the trip from her perspective. She is frustrated by Shōko’s lack of gratitude and emotional engagement. She has a painful realization: Shōko’s blog prose was not elusive because of a rich inner world, but because Shōko has narrow interests and little to say. Feeling embarrassed by her intense obsession with such a shallow person, Eriko longs for the comfort of her home and mother. The fear of growing old while remaining emotionally immature terrifies her. Despite her disappointment, she clings to the idea that she and Shōko can form a powerful partnership, compensating for each other’s weaknesses. She is left with a deep sense of loneliness, however, aware that Shōko does not share her vision for their friendship.
Now back in her own apartment, Shōko reads Eriko’s blog post about the Hakone trip. She finds the writing sterile and desperate, noting that the blog’s traffic has hit an all-time low. It is revealed that Shōko faked severe period pain on the trip’s second day to go home early, leaving Eriko to finish the tour alone for the sake of the blog’s content. Feeling trapped and certain Eriko will soon contact her again, Shōko drafts an email to Nori, a fellow blogger, asking for advice on how to deal with an obsessive fan who has taken control of her blog. Later, she suggests to her husband Kensuke that they have a baby, offering to get a part-time job to help financially. When she tries to kiss him, however, she is overwhelmed by the memory of kissing Hashimoto and recoils. She considers confessing everything but decides against it, terrified of destroying her marriage which she views as her only sanctuary.
Shōko and Eriko meet again at a Denny’s, where Shōko calmly announces her intention to quit the blog permanently to protect her private life. Enraged by this rejection, Eriko once again threatens to release the photo of Shōko kissing Hashimoto. After they leave, Eriko insists that Shōko give her a ride on the back of a bicycle as she did before. Shōko struggles under Eriko’s increased weight, causing them to crash. As Shōko cowers on the ground, Eriko catches her own reflection in a darkened shop window and is shocked to see how much weight she has gained. This moment of clarity forces her to recognize that her obsession is futile and that their friendship is impossible. She deletes the blackmail photo from her phone in front of Shōko, tells her she is no longer needed, and walks away alone. Shōko watches her go, crying.
After Eriko ended the blackmail, Shōko felt a wave of exhilaration and confessed her infidelity to Kensuke. Devastated, he told her he could no longer live with her. Now, Shōko is on a train to her estranged father’s house, having received no word from Kensuke. She sends a desperate message to the blogger Nori, mentioning her potential divorce. Upon arriving in her hometown, she has a chance encounter with her cousin, Miwa, who is also divorced and living with her parents. They exchange numbers and make plans to meet. Shōko then reaches her father’s house and finds it unlocked and in a state of horrific decay. Overwhelmed by despair, she collapses, feeling destined to be consumed by the home’s loneliness. Moments later, she discovers her father’s cold, unmoving body. Her first reaction is an intense, overwhelming sense of liberation, though she notices a rash developing on the fingertips that touched him.
Eriko’s colleague, Yasuyuki Sugishita, visits her at her parents’ home. Earlier that day, Eriko’s mother had a breakdown, screaming that she had sacrificed her career and life for her ungrateful husband and daughter. Sugishita notes Eriko’s significant weight gain, and she admits to having had an eating disorder. He complains that his wedding to Maori has been postponed because Maori is prioritizing her friends and wedding planning over him. Eriko realizes he came seeking an ego boost, which her changed appearance has denied him. He complains that “a woman’s worst enemy is other women,” (328) and Eriko reflects that Sugishita, like herself, is fundamentally broken in his expectation of unconditional affection. Before leaving, Sugishita delivers a message: Naomi, the local coordinator from their work trip in Tanzania, was very concerned when she heard Eriko was on leave. The unexpected news of Naomi’s kindness touches Eriko deeply.
At a soba restaurant in Hakone, Eriko delivers an articulate monologue on how society forces women to compete like invasive species, proposing that she and Shōko “become an invincible duo” (274) to fight this system. This speech reveals a critical disconnect between Eriko’s intellectual understanding and her emotional reality. She identifies the patriarchal framework that fosters female rivalry—a dynamic encapsulated in the Japanese cultural trope of doro-doro friendships—yet her proposed solution is another form of consumption and control rather than genuine solidarity between herself, Shōko, and other women. The speech is an explicit invocation of the symbol of the Nile perch, casting women as creatures pitted against each other in an unnatural ecosystem created by outside forces. In her desperate attempt to forge a powerful alliance, however, Eriko ironically becomes the invasive predator herself, trying to take over Shōko’s life. This contradiction is foreshadowed moments earlier, when she dismisses a TV show because she “couldn’t really relate to the main character” (271), exposing a worldview where empathy is contingent on self-recognition. Eriko cannot forge a true bond because she is incapable of seeing Shōko as anything other than a mirror or a project, a failing that emphasizes the theme of The Impossibility of Self-Actualization Under Patriarchy. Even when a character can diagnose the illness, the patriarchal values of competition and control are so deeply internalized that she cannot conceive of a cure that isn’t itself toxic.
The Hakone trip and its aftermath expose the illusion at the heart of the blog. As a document of their trip, the blog becomes pure fiction, with Eriko meticulously photographing untouched food and writing “cheerful, perfectly illuminated prose” (294) about a journey Shōko found unbearable and cut short. The subsequent plummet in site traffic demonstrates that the blog’s appeal was rooted in an authenticity Eriko cannot replicate, even if she can use Shōko’s phrasing and style. Her writing is sterile because it is a performance of friendship, rather than the product of one, a failure that speaks to the theme of The Dangers of Parasocial Relationships. Eriko’s obsession was built on a curated digital identity she fundamentally misunderstood. She consumed the blog as a reflection of her own desires, projecting a rich interiority onto a woman who, she painfully realizes, “really had nothing to say” (289). When Shōko reads Eriko’s post, she hears the writer’s “screams of desperation” (294), recognizing the deep loneliness driving the performance. Shōko’s decision to quit blogging is a definitive rejection of this parasocial dynamic, an attempt to reclaim her private life from the demands of an audience and an obsessive fan who tried to possess it.
The narrative structure of the Hakone chapters, which alternates between Shōko’s and Eriko’s perspectives, emphasizes their deep and mutual incomprehension. In Chapter 25, Shōko mentally reduces Eriko to a “human-shaped bolster” and a “puppet” (266) to endure the trip, seeing her behavior in the onsen as proof that Eriko is emotionally a “child” (282). Conversely, in Chapter 26, Eriko’s internal monologue reveals her frustration with Shōko’s passivity and her crushing disappointment upon realizing Shōko’s online persona was a void. This dueling point-of-view technique creates a dramatic irony where the reader is the only one aware of the vast gulf between their experiences. They share a room, a meal, and a bath, yet remain utterly isolated within their own subjective realities. This structural choice illustrates the theme of The Alienating Nature of the Modern World, showing how physical proximity fails to guarantee connection. Their inability to bridge this internal distance demonstrates that their relationship was never a dialogue. It was always two competing monologues, a core dynamic of their failed friendship.
Eriko’s psychological breakdown is precipitated by a stark encounter with her own physical body. The bicycle crash, a failed attempt to restage their first joyful ride, occurs because Shōko can no longer bear Eriko’s literal and metaphorical weight. Thrown to the ground, Eriko catches her reflection in a shop window and is horrified by her own changed appearance, a moment of anagnorisis that shatters her delusion. The physical self she has neglected in her obsession becomes undeniable proof that the “Eriko Shimura that existed in her imagination” (309) is gone. This moment of clarity is contextualized by her mother’s earlier breakdown, a raw outburst that reveals the supposedly idyllic family home is also a site of female repression and sacrifice, a truth which eluded Eriko for much of her life. Later, when her colleague Sugishita lazily repeats the misogynistic trope that “a woman’s worst enemy is other women” (328), Eriko’s quiet reflection that he, too, is broken shows significant growth. She has moved from imposing her worldview on others to recognizing a shared human frailty.
This section culminates with both protagonists achieving a brutal form of liberation through the collapse of their primary social structures. After Eriko frees her, Shōko feels a “heady exhilaration” (316) that prompts her to confess her infidelity to Kensuke, an act that promptly destroys her marriage, her “only sanctuary” (295). Forced to return to her family home—a site of decay and entrapment—she discovers her father’s prone body. Rather than feeling grief, she is surprised to feel an overwhelming sense of liberation, a psychologically honest response to the end of a lifetime of oppressive paternal influence; her mind immediately goes to the song Ding-Dong! The Witch Is Dead, framing his death as the defeat of a tyrant. Both women are stripped of their defining relationships: Shōko of her husband and father, Eriko of her obsessive focus. They are left alone, yet this isolation creates an opening for something new. Shōko’s brief, positive encounter with her cousin Miwa, a woman in a similar situation, offers the first glimmer of a healthy, reciprocal female bond based on shared reality, a stark contrast to the toxic fantasy she has just escaped.
