The History of Japan’s Black Markets: From the Jomon Period to the Digital Age

Introduction: The Invisible Economy and the Human Condition

The black market is a phenomenon deeply woven into the fabric of Japanese society throughout its history, representing more than just illegal economic activity. It symbolizes a broader narrative of human desire, necessity, and curiosity challenging formal institutions and regulations. This report defines the black market as a form of illicit trade, comprising unrecorded, unreported, or informal economic activities that emerge in response to institutional rules, regulations, and prohibitions. The analysis is predicated on the idea that a formal “white market” and a government with a monopoly on enforcement must first exist for a black market to take root.

At its core, this report tells the story of the constant, and often futile, struggle of rulers and governments to control the flow of goods, ideas, and actions. Throughout history, demand has consistently triumphed in this conflict. This is underpinned by the double-edged sword of human curiosity, which, according to psychological theories, is an intrinsic human drive that intensifies when forbidden. Psychological reactance theory suggests that when people feel their freedom is restricted, they are motivated to restore it, making the forbidden item or act more appealing. This is closely related to the scarcity principle, where the value of an item skyrockets due to its limited availability. This psychological dynamic was at play, for example, during the Edo period’s isolationist policy, or sakoku. The government’s attempt to exclude Christianity and foreign goods amplified the demand for banned texts and rare imports, transforming the black market into a space of psychological rebellion.

Part 1: Ancient Proto-Markets (Jomon to Heian Periods)

To understand the history of Japan’s black markets, we must first start with a time before the state and its laws existed. In the Jomon period (c. 14,000–300 BCE), there was no centralized government, legal code, or official currency. However, vibrant trade networks existed across regions. Goods like obsidian (a volcanic glass used for sharp tools), jade ornaments, asphalt, and rare seashells from the south were traded over long distances. While the concept of a “black market” didn’t exist, this system of exchange proves that the fundamental human impulse for commerce exists independently of institutional regulation. It shows that the desire for the rare, the beautiful, or the useful was a natural force that predated the rise of the state.

The black market concept only emerged with the formation of the state. From the Yayoi to the Kofun and Heian periods, political centralization began with the rise of the Yamato court, which made the first attempts to control overseas trade, particularly with mainland Asia. The introduction of the ritsuryo system (a legal and administrative system modeled on Chinese codes) formalized commercial activity and social order, for the first time defining “legal” and “illegal” and creating the conditions for black market activities.

The Wako, or “Japanese pirates,” who emerged during this period were the first major organized black market players in Japanese history. They were not merely raiders but also “pirate-merchants,” who exploited the vacuum created by China’s Ming dynasty’s haijin policy (sea ban) to facilitate illicit commerce. The rise of the Wako clearly illustrates the historical pattern of a government’s attempt to control markets unintentionally creating powerful criminal forces.

Part 2: The Edo Period: The Golden Age of Smuggling (1603–1868)

The Edo period is the most prominent example of the black market’s development in Japan, showcasing the conflict between strict state control and human desire. The Tokugawa shogunate’s sakoku policy was primarily aimed at excluding the influence of Christianity, solidifying central power, and preventing powerful daimyo (feudal lords) from gaining strength through foreign trade. It also sought to protect traditional culture and promote self-sufficiency. However, the isolation was not absolute. Official trade was maintained with the Dutch and Chinese at Nagasaki, the Koreans at Tsushima, the Ainu at Matsumae, and the Ryukyu Kingdom at Satsuma.

The most interesting contradiction of this policy was that while the shogunate intended to centralize power, it inadvertently created an environment for some daimyo, like the Satsuma and Tsushima domains, to profit immensely from unauthorized trade. This is a perfect example of how top-down prohibitions fail to account for local economic incentives and the unstoppable pressure of demand.

Smuggling was conducted by Chinese ships “feigning distress” on the southwestern coasts of Japan. There were also merchants like Zeniya Gohei and even powerful domains like Satsuma, which relied on illicit trade for their finances. Penalties for smugglers were severe, including crucifixion, but the profits were too great to deter the activity. Enforcement was described as a “paper screen with holes in it,” with officials often looking the other way or even colluding.

The black market was not only a result of foreign trade restrictions but also of domestic, class-based sumptuary laws (shashi kinshirei). Wealthy commoners would circumvent these laws and flaunt their wealth by wearing plain cotton kimonos with luxurious silk linings. This is a perfect example of how human curiosity and desire for status can outwit regulation.

The Dutch interpreters on Dejima played a crucial role in this era’s black market. They were not just translators but government officials with diverse duties, including overseeing trade agreements, settling disputes, and monitoring the Dutch. Their position as the sole point of contact between two isolated worlds gave them access to both valuable information and forbidden goods, making them ideal “fixers” for smuggling. The government’s attempt to strictly control the system inadvertently gave those who managed the bottleneck new opportunities for illicit activity.

The roots of the modern Yakuza can also be traced to this period, with the emergence of two groups in the mid-Edo era: the tekiya, or peddlers of illegal and stolen goods, and the bakuto, who engaged in gambling. Their rise was a social response to the merchant class accumulating wealth while being placed at the bottom of a rigid social hierarchy. The Yakuza filled a societal gap by creating their own power structure outside the official class system, providing services like allocating peddling spots and security.

Part 3: From the Meiji Restoration to WWII: Scarcity and the Shadow Economy

The Meiji Restoration shifted the nature of Japan’s black markets from controlling ideas and luxury goods to supplying necessities created by political upheaval and economic collapse. The chaos of this era created new black market opportunities. Figures like the foreign merchant Thomas Glover smuggled weapons and steamships to rebel forces like the Satsuma and Choshu domains, helping to shape Japan’s political future as the shogunate’s authority waned. This is an example of how political vacuums and a demand for technology (firearms) can create new illicit economies. Glover’s actions were a modern reflection of the Edo-period interpreters, as he was a foreign “fixer” who exploited a political gap for profit.

During and after World War II, “black markets” (yami-ichi) proliferated in the burned-out cities. While many believe they suddenly appeared from the chaos of the war’s end, they actually grew incrementally from the “economy of scarcity” created by wartime controls and rationing that began in the late 1930s. The yami-ichi became a lifeline for people who couldn’t get essentials like rice, sweet potatoes, sugar, and clothing through official channels.

The black markets were not always seen negatively; they functioned as an “informal safety net” for the unemployed, war orphans, and widows, sustaining people’s lives. Interestingly, while the government officially tried to stamp them out, there was a degree of complicity as an “emergency measure” for economic recovery. This is a complex example of how a state is forced to rely on informal systems when its public economy collapses.

Part 4: The Age of Globalization and Technology

Modern black markets have fundamentally changed due to globalization and technology. Japanese organized crime, the Yakuza, has diversified its activities from the Edo-period street vendors and gamblers to more profitable, white-collar crimes including international drug trafficking and money laundering. Their declining official membership numbers don’t signify their demise but rather a shift to more secretive, lucrative ventures.

The role of the “fixer” in modern black markets persists across eras. The case of Ippei Mizuhara, the former interpreter for baseball player Shohei Ohtani, who embezzled millions, can be seen as a modern parallel to the Edo-period Dutch interpreters. Mizuhara was a trusted intermediary between two isolated worlds: Japanese culture and the US business and legal systems. This shows how the human role of exploiting gaps in systems that the government tries to strictly control remains essentially unchanged.

EraLogistics/Smuggling MethodCharacteristics/Changes

Meiji PeriodSteamships, railwaysIntroduction of Western technology revolutionized smuggling. Weapons and imports could be transported faster and in larger quantities.
Post-WWIICity stalls (yami-ichi), military surplusThe collapse of rationing and scarcity led to the physical emergence of black markets in city centers.
Modern EraInternational mail/parcels, Dark Web, drones, cryptoGlobalization and digitalization allow for anonymous, cross-border transactions. Shift from physical smuggling to cybercrime.

Part 5: Philosophical Reflections and Future Outlook

The history of Japan’s black markets is a physical manifestation of fundamental human curiosity and desire—driven by psychological reactance and the scarcity principle. When governments create taboos around ideas, art, or, in the modern era, drug use, the black market provides a means to bridge that “information gap” and satisfy that desire.

We can imagine a future with the AI revolution where humanity’s basic needs and intellectual curiosity are satisfied. In a world where information is universally accessible and the impulse for material acquisition for survival is gone, the black market’s very raison d’être might crumble. This holds the potential for humanity to evolve spiritually without being driven by the “dialectical interplay” between scarcity and opportunity.

Technology might even fill the gaps that the black market exploits, finding a “sweet spot” between the “black” and “white” markets. Technologies like blockchain could bring transparency and security, potentially building a more equitable system for distributing goods and knowledge. If technology can solve scarcity and provide universal access to both material and intellectual knowledge, the fundamental conditions that have produced black markets from the Jomon period to today may no longer exist.

Conclusion: The Persistent Shadow

From its beginnings to the modern era, the history of Japan’s black market has been an adaptable and fluid phenomenon. It began the moment a state-controlled boundary was established and has been driven by the human desire to cross that boundary.

The existence of the black market remains constant even as the times change. Whether it was the smuggling of the Edo period, the yami-ichi of the post-war era, or the modern digital underworld, the form may change, but its essence is always to fill the gaps in demand that government regulations fail to meet.

Ultimately, the black market is a mirror of human nature. As long as society creates scarcity and defines what is “forbidden,” the black market will be the persistent shadow. While the dance between state enforcement and black market avoidance continues, the fundamental forces of human desire and curiosity will always remain.
