What is Butter by Asako Yuzuki?
A Brief Overview
Published in 2017 in Japan and translated into English in 2024 by Polly Barton, Butter is a novel inspired by the real-life case of Kanae Kijima, a woman convicted of killing several men she met on dating websites. However, Yuzuki’s version reimagines the narrative through a feminist lens, exploring deeper psychological and societal issues.
At the heart of the story is Rika Machida, a Tokyo-based journalist investigating the crimes of Manako Kajii, a charismatic woman accused of seducing and killing wealthy men using her culinary skills. As Rika delves deeper into Kajii’s world, she begins questioning her own life, ambitions, and the toxic expectations placed on women.
Key Themes Explored in Butter
Food as Power and Expression
Manako Kajii’s relationship with food is central to the narrative. She uses cooking not just as a means of seduction but as a mode of self-expression and rebellion. Food in Butter becomes a metaphor for nourishment, manipulation, sensuality, and control.
Femininity and Societal Expectations
The novel dissects how Japanese society imposes strict standards on women regarding beauty, success, and behavior. Rika’s internal conflict mirrors that of many professional women juggling societal judgment and personal desires.
Media Sensationalism and Misogyny
The depiction of Kajii in the press echoes the real-life portrayal of Kanae Kijima—villainized, objectified, and reduced to a caricature. Yuzuki critiques how media narratives are shaped by gender bias and public voyeurism.
Loneliness and Connection
Despite being accused of heinous crimes, Kajii emerges as a profoundly lonely figure. Her correspondence with Rika opens up an unexpected bond, blurring the lines between hunter and prey, villain and victim.
Plot Summary
Rika Machida is assigned to write a feature on Manako Kajii, a woman awaiting trial for the suspected murder of several men. Intrigued by Kajii’s calm demeanor and her obsession with gourmet cooking, Rika begins a series of prison visits. Kajii refuses to talk about the crimes but is more than willing to discuss recipes, ingredients, and culinary philosophies.
As Rika gets drawn into Kajii’s orbit, her perspective on her own life begins to unravel. She reflects on her joyless job, estranged family relationships, and lack of personal fulfillment. Kajii becomes a mirror reflecting Rika’s hidden desires and fears. Through food, letters, and late-night cooking sessions, the two women form a complicated relationship that challenges the boundaries of morality, identity, and truth.
Real-Life Inspiration: The Kanae Kijima Case
Kanae Kijima, often dubbed the “Black Widow” by Japanese media, was convicted in 2012 of murdering three men she met online. She allegedly used seduction and financial manipulation to control her victims. Yuzuki’s novel does not seek to exonerate or glorify such crimes but uses them as a backdrop to critique the sensationalism and gender politics in Japanese crime reporting.
Why Butter is Resonating in 2025

FAQs
Is Butter based on a true story?
Yes, Butter draws inspiration from the real-life case of Kanae Kijima, a Japanese woman convicted of killing three men she met through online dating platforms.

This layered approach gives Butter its literary strength and emotional depth.
