In the canon of classic children’s literature, few books merge the philosophical with the personal quite as gracefully as Genzaburo Yoshino’s How Do You Live?. The novel was first published in 1937 and has held a profound place in Japanese literary history, mainly for portraying a young boy’s journey toward self-awareness. In 2021, the book was translated into English, giving this once-obscure work a new life. How Do You Live? has been cited by Hayao Miyazaki in many interviews as his favorite childhood book and a source of inspiration for many of his films. With his latest film, The Boy and the Heron, which was initially titled How Do You Live? for international and Japanese markets, Yoshino’s novel inspired yet again, with the film exploring the same themes as the book. And while The Boy and the Heron wasn’t a direct adaptation, the book provides the vital cultural and intellectual backdrop for the Oscar-winning animated film.

How Do You Live? centers on a 15-year-old boy named Junichi Honda, affectionately nicknamed “Copper” after Copernicus, and his uncle, whose guidance comes in the form of a diary. Copper, an academically gifted and kind-hearted teenager, must navigate adolescence, grappling with morality, friendship, and social justice questions. The novel’s structure is unique, interweaving Copper’s daily life in pre-war Tokyo with meditative entries from his uncle’s journal, which explore everything from ethics and economics to science and history. This two-pronged approach makes the book more than just a coming-of-age story—it teaches how to live a thoughtful, ethical life.
The context of the novel’s publication is critical. In 1937, Japan was on the cusp of full-blown militarism as nationalist fervor surged and the country escalated its invasion of China. Against this backdrop, Yoshino’s work is a subtle, even subversive, critique of the era’s dominant political ideology. Yoshino, a leftist intellectual who had spent time imprisoned for his political beliefs, infuses the novel with a humanist philosophy that was at odds with the rising tide of authoritarianism. His exploration of class inequality, empathy, and the value of personal integrity stood in stark contrast to the militaristic values of the time, making How Do You Live? a courageous, albeit risky, act of dissent.
One of the novel’s most poignant moments comes when Copper visits a classmate, Uragawa, who is bullied for his family’s poverty. Through this encounter, Copper gains a deeper understanding of social inequality—an experience that his uncle later contextualizes in his diary as a lesson in the moral responsibility of the privileged. These diary entries, which form the book’s philosophical backbone, offer meditations on topics like wealth disparity, the nature of heroism, and the importance of intellectual curiosity. In Yoshino’s hands, these lessons are not dry lectures but deeply personal reflections on the human condition.

For Hayao Miyazaki, whose films frequently explore themes of environmentalism, pacifism, and the human spirit, How Do You Live? undoubtedly served as a wellspring of inspiration. Miyazaki has often used his films to question Japan’s relationship with modernity and militarism, much as Yoshino did with his novel. The connection between the two artists lies not just in their shared themes but in their insistence on the transformative power of imagination and reflection.
Despite the novel’s clear political undertones, How Do You Live? never loses its focus on the universal dilemmas of growing up. Copper’s struggles—his guilt over betraying a friend and his attempts to make sense of a world that often feels unjust—are timeless. Yoshino’s gentle, poetic prose ensures that the novel resonates across generations. The recent English translation by Bruno Navasky captures the lyricism of Yoshino’s original text and the clarity of its philosophical musings.
As Neil Gaiman notes in his foreword, readers may initially find the novel’s pace slow, especially given its tendency toward introspection. However, this reflective quality is precisely what makes How Do You Live? so enduring. It is not a book driven by action but by thought, asking readers to pause and consider the deeper questions it raises about our responsibilities to ourselves and to others.

In many ways, Yoshino’s novel is a testament to the power of quiet resistance. Published when dissent was dangerous, How Do You Live?‘ offers a model of ethical living that transcends its historical moment. Its core message—that our humanity is defined by how we treat others, especially in times of hardship—remains as relevant today as it was in 1937. For readers in search of a book that challenges, enlightens, and ultimately uplifts, How Do You Live? is a rare gift.
In a final, poignant touch, the novel’s omniscient narrator turns to the reader with a direct question: “How will you live?” This question lingers long after the book is closed, offering not a conclusion but an invitation to reflection—a timeless appeal in an increasingly fractured world.
Genzaburo Yoshino’s legacy, now revived for a global audience, stands not only as a cultural artifact of Japan’s pre-war era but also as a guide to navigating the ethical complexities of life itself. I give this masterpiece, How Do You Live?, 5 out of 5 sobees.
