Butter by Asako Yuzuki is worth reading for its unique blend of true crime, food writing, and feminist social commentary. Named Waterstones Book of the Year in 2024, the novel offers vivid, descriptive language around food and a mesmerizing character study. While the pacing is deliberately slow and contemplative, readers who appreciate nuanced explorations of identity, misogyny, and the relationship between women and food will find Butter deeply rewarding.
Butter by Asako Yuzuki is inspired by the real 2012 case of Kanae Kijima, known as "The Konkatsu Killer". Kijima was a Japanese woman convicted of killing three romantic partners, allegedly using her cooking skills to seduce lonely businessmen. While Asako Yuzuki drew inspiration from this sensational case, Butter is a fictionalized exploration that uses the premise to examine deeper themes of gender, food, and power in contemporary Japan.
Butter by Asako Yuzuki explores identity, gender politics, and feminism in modern-day Japan through the lens of food and female relationships. The novel examines how societal expectations shape women's relationships with their bodies, food, and pleasure. Key themes include obsession, loneliness, misogyny, and how food connects us to childhood, community, and future generations. The book challenges capitalistic structures and questions what it means for women to fully enjoy life.
In Butter by Asako Yuzuki, butter symbolizes authenticity, pleasure, and rejection of artificial substitutes—both in food and in life. The convicted killer Manako Kajii famously states she cannot tolerate "feminists and margarine," positioning butter as representing genuine indulgence versus society's cheaper alternatives. Throughout the novel, butter becomes a metaphor for embracing real experiences and pleasures that women are often discouraged from enjoying. It challenges protagonist Rika to reconsider what authenticity means in her own life.
Butter by Asako Yuzuki examines how patriarchal expectations limit women's autonomy over their bodies, careers, and desires in contemporary Japan. Protagonist Rika works as the only woman in her news office, constantly navigating workplace sexism while neglecting her own needs. The novel contrasts different responses to misogyny: Rika's self-denial versus Kajii's unapologetic indulgence. Asako Yuzuki critiques how society polices women's bodies, appetites, and life choices while exploring the complex relationship between female empowerment and transgression.
In Butter by Asako Yuzuki, journalist Rika Machida develops a dangerously intimate bond with convicted killer Manako Kajii through their exchanges about food and cooking. What begins as journalistic research transforms into something closer to mentorship, with Kajii teaching Rika to appreciate culinary pleasures and question her self-denial. Their relationship becomes obsessive and boundary-blurring, forcing Rika to confront uncomfortable similarities between herself and the convicted murderer. The dynamic explores power, manipulation, and feminine solidarity.
In Butter by Asako Yuzuki, food serves as a vehicle for self-discovery, sensuality, and rebellion against societal constraints. Through detailed descriptions of meals—from simple rice with butter to elaborate beef stew—Asako Yuzuki connects food to identity, memory, and bodily autonomy. For protagonist Rika, who survives on instant ramen, learning to cook and savor meals becomes an act of awakening to her own desires. Food represents the transgressive pleasure of women claiming space and appetite in a restrictive society.
Butter by Asako Yuzuki's deliberately slow pacing may frustrate readers expecting a fast-paced thriller despite its true crime premise. Some critics note the novel's contemplative, character-driven approach requires patience as it prioritizes food descriptions and philosophical musings over plot advancement. The book's exploration of Japanese gender dynamics may also feel culturally specific to Western readers unfamiliar with contemporary Japanese society. However, readers who embrace its literary ambitions generally find the methodical pacing enhances the story's seductive, unsettling atmosphere.
Readers who enjoyed Butter by Asako Yuzuki might appreciate Kitchen by Banana Yoshimoto for its Japanese literary perspective on food and identity, or Convenience Store Woman by Sayaka Murata for explorations of women defying societal expectations in Japan. The Thick and the Lean and Land of Milk and Honey offer similar food-centric narratives examining power and consumption. For true crime with literary ambition, try My Sister, the Serial Killer by Oyinkan Braithwaite or The Silent Patient by Alex Michaelides.

In the midst of Japan's nationwide butter shortage, journalist Rika Machida finds herself drawn into the world of Manako Kajii, a plus-sized woman accused of murdering three men she met through dating services. What begins as professional curiosity evolves into dangerous obsession as Rika discovers there's something admirable in how Kajii demanded good treatment despite societal expectations-a sharp contrast to the self-restraint Rika observes in successful women around her and feels in herself. That constant pressure to remain small, both physically and metaphorically. When Kajii finally agrees to meet at the women's detention center, she establishes clear boundaries-she won't discuss her case but will talk about food, her passion. Upon hearing Rika has been using margarine during the butter shortage, Kajii launches into a passionate diatribe, eyes flashing with genuine anger: "I cannot tolerate feminists and margarine." She instructs Rika to make rice with premium Echire butter and soy sauce, describing the experience with almost religious reverence: "When I'm eating good butter I feel somehow as though I were falling...The body plummets, starting from the very tip of the tongue." This moment marks the beginning of Rika's dangerous seduction into a world where pleasure takes precedence over restraint, where food becomes almost erotic in its intensity, and where the boundaries between indulgence and destruction begin to blur ominously.
