Feminist scholars also note the irony of the name “Nana” (often a girl’s name) attached to a distinctly male archetype. Some have reclaimed this by arguing that the folkloric Nana transcends gender: the virtues of diligence, frugality, and lifelong learning are universal. In recent years, manga and anime adaptations have reimagined Nana Ninomiya as a female character or a non-binary sage, sparking new interest in the old tales.

But who was the real Nana Ninomiya? How did a real-life economist from the late Edo period transform into a folkloric hero and a symbol of the Nippon seishin (Japanese spirit)? This article delves deep into the life, legend, and legacy of Kinjiro Ninomiya, exploring why his story continues to resonate in a world of instant gratification and digital distraction. To understand the legend, one must first separate the man from the myth. Sontoku Ninomiya (1787–1856) was born into a prosperous farming family in the village of Kayama, Sagami Province (modern-day Odawara, Kanagawa Prefecture). However, tragedy struck early. When Kinjiro was just a child, his father fell ill and passed away, followed shortly by the death of his grandfather. The family’s fortunes reversed dramatically. Their land was seized by creditors, and the once-secure household fell into destitution.

These statues were mass-produced from the 1890s to the 1940s as part of the Imperial Rescript on Education’s drive. By 1945, over 80% of public elementary schools in Japan had one. They were placed at entrances or in courtyards, so that every child would walk past this image of disciplined multitasking every single day. The statue was not a monument to be worshipped; it was a mirror to be internalized.

But his greatest contribution was philosophical. In his later years, Ninomiya synthesized his experiences into a system called Hotoku (報徳)—the "Way of Repaying Virtue." He argued that individuals and communities could prosper by integrating three fundamental activities: work (勤労), thrift (節倹), and altruism (推譲). He famously rejected pure charity, believing that handouts weakened the spirit. Instead, he advocated for sukui (help) that required reciprocal effort. This is why his statues are never of a passive scholar, but of an active worker who reads—a symbol of synthesis, not escape. So how did Sontoku Ninomiya become Nana Ninomiya? The answer lies in the Meiji Restoration (1868). The new imperial government needed to forge a modern, unified national identity. They looked to historical figures who embodied loyalty, diligence, and self-improvement. Ninomiya Sontoku was perfect.

Another folk variant, less known but equally revealing, casts Nana as a trickster figure. In this story, a lazy neighbor asks how Nana succeeds. Nana replies, “I simply walk backward.” The neighbor, literal-minded, tries walking backward and trips. Nana laughs and says, “I meant I look backward at my past mistakes while moving forward into the future.” This playful, Socratic wisdom became a hallmark of the folkloric Nana Ninomiya—a figure who outsmarts not through wealth or strength, but through wit and virtue. If you visit any pre-war elementary school in Japan, you might find a bronze statue of a boy with a shaven head, wearing a hanten (work coat) and geta (wooden clogs), carrying a bundle of firewood cross-hatched on his back, with a book—often an open scroll or a small bound volume—held in front of his face. This is the Nana Ninomiya statue.

His brilliance did not go unnoticed. A local magistrate, Suzuki Shigeyoshi, recognized the boy’s potential and hired him as an assistant. Kinjiro’s ability to solve complex administrative problems, from irrigation disputes to tax collection, stunned his elders. By his early twenties, he had restored his family’s fortune and began working as a land reclamation specialist for the Tokugawa shogunate. He revived hundreds of villages, built flood controls, and established mutual aid societies.

There is also the environmental reinterpretation. The rapeseed plant, central to the folk story, is now seen as a symbol of circular economy—seed to oil to light to compost back to seed. In this reading, Nana Ninomiya is not a workaholic but a proto-ecologist, modeling a life of zero waste and deep harmony with the seasons. Visit Odawara City on November 17th, and you will witness the Ninomiya-sai festival. Children dress in Edo-period farm clothes, carrying miniature bundles of firewood and reading aloud from The Analects or modern picture books. They compete in Hotoku essay contests, writing about how they apply thrift and hard work to their own lives—saving pocket money for a family trip, helping a neighbor with groceries, or studying for exams without cram school.
