Undocumented and overstayed foreign workers in Japan

Undocumented and overstayed foreign workers in Japan occupy a precarious position between the demand for their labor and the rules that make their presence vulnerable to punishment. The book traces how economic policy drew workers into Japan, how insecure immigration status could silence them in the face of extortion or exploitation, and how enforcement aimed at immigration violations could obstruct efforts to protect victims and prosecute those exploiting them.

Labor Demand and Changing Policy

In the late 1980s, when Japan’s economy was booming and construction was widespread, an agreement between Japan and Iran allowed Iranians to work in Japan without a visa. The book describes this arrangement as part of an unofficial government policy to supply the country with inexpensive manual labor. Many Iranians came to Japan and remained beyond the period in which their stay was authorized.

Their employment reflected a mismatch in the labor market. Young Japanese workers increasingly avoided jobs described as 3K: kitanai, or dirty; kitsui, or difficult; and kurushii, or painful. When the economic bubble deflated in 1993, the agreement with Iran was canceled, but factories and heavy industry in Chichibu still offered work. The change in policy did not immediately remove the need for the labor already being supplied by Iranian workers; it left some of them working in a less secure position.

The book shows the consequences of that gap when police investigating a murder in Chichibu sought the daughter’s Iranian boyfriend, who was missing. Rather than having a clear lead to him, the Saitama police rounded up every Iranian worker they could find in the area. The search was expected to take time. For workers whose immigration status was already precarious, being drawn into a criminal investigation could therefore mean exposure to immigration enforcement as well as questioning about the case.

Status as Leverage

A separate episode involving Israeli street vendors shows how immigration status could give others leverage over foreign workers. Vendors sold goods near a station, including items brought from Nepal or Tibet and counterfeit brand-name watches and handbags purchased in Thailand. A pair of yakuza demanded a share of one vendor’s earnings in public; the vendor said they took between thirty and thirty-five percent of what he made.

The vendor explained that the collectors estimated earnings by comparing what remained on the stand when they returned. He did not regard going to the police as a viable option: he was in Japan on a tourist visa and feared that reporting the extortion would lead to his own arrest and imprisonment. His account presents a practical trap rather than a simple choice between reporting a crime and remaining silent. The threat of immigration consequences made the worker easier to exploit and allowed the extortion to continue without a complaint.

The same vulnerability appears in the experiences of women recruited from Poland and other parts of Eastern Europe. Veronika said that she had answered an internet advertisement promising hostess work, traveled to Japan, and surrendered her passport after being told it would be kept safe. She later discovered that the work offered was different from what she had been promised. The people controlling her documents invoked her lack of a passport and the risk of being treated as an illegal resident to discourage her from seeking police help. She was also afraid that the men who had recruited her could harm her family. Her account illustrates how deception, control of travel documents, debt, and threats could combine with insecure status to restrict a worker’s ability to leave or seek assistance.

The pressures extended beyond individual recruitment. Veronika described other women who were afraid to approach police because they expected arrest, feared prison, or worried about the consequences of being unable to repay a debt. The book also records a worker’s description of foreign women at her workplace as being forced to work without pay. These accounts make clear that a person’s initial agreement to travel or take a job did not mean that she could freely refuse the conditions imposed after arrival.

Enforcement and the Protection Gap

The conflict between victim protection and immigration enforcement is stated directly in a conversation about obtaining testimony against the operators of a trafficking business. The officer proposed arresting and deporting a woman who came forward on a tourist visa, while using her testimony to pursue the men for immigration violations and other possible offenses. The narrator objected that this approach would make it unlikely that an exploited worker would agree to testify.

A National Police Agency directive called on police to make serious efforts to close human-trafficking operations and care for victims. The officer nevertheless said that there were no criteria for identifying trafficking victims and that police could not simply overlook illegal work and provide shelter. In his account, an officer who declined to arrest a worker for an immigration violation could be accused of neglecting official duty. The result was a structural contradiction: a worker’s testimony might help investigators act against traffickers, but coming forward could expose that same worker to arrest and forced repatriation.

The officer also connected the lack of a victim-identification process to the difficulty of building cases. If people deceived into working were classified only as illegal workers and deported, investigators lost potential witnesses. Immigration enforcement could therefore remove the very people whose evidence might support a prosecution. The book presents this not merely as an individual officer’s reluctance but as a gap between national instructions and the practices available to police on the ground.

Public Disclosure and Consequences

The book’s account of the policy response shifts attention from individual offenders to the government’s handling of the wider problem. The International Labour Organization had conducted a Japanese-government-funded study of human trafficking in Japan. The report criticized the government’s failure to punish traffickers and care for victims, but the government ordered that it remain unpublished.

The narrator obtained a copy through sources and secured a Yomiuri Shinbun front-page story on November 19, 2004, followed by another article the next day. A source said the government had been preparing an action plan and that the reporting prompted substantial revisions to strengthen victim protections. The account does not present publication as a complete remedy; it records a specific change in policy preparation after the gap between official commitments and conditions facing workers had been brought into public view.

The book also notes that the two men at the center of that trafficking investigation eventually went to jail through separate routes. Police raided Slick’s clubs after the drug squad took an interest in him, and he went out of business; information supplied to Japanese Customs and Dutch police contributed to Viktor’s imprisonment. These outcomes contrast with the earlier obstacles to obtaining victim testimony, but they do not erase the vulnerability that made the exploitation possible. Across the episodes, insecure immigration status is shown both as a condition created by labor demand and as a mechanism that could deter reporting, weaken investigations, and shift the immediate burden of enforcement onto workers.
