Japan’s foreign labor policy is often discussed as a domestic issue.
Debates typically focus on labor shortages, economic growth, or social integration within Japan.
However, one crucial perspective is frequently overlooked:
Foreign worker policy is inherently bilateral.
Migration does not occur in a vacuum.
It connects two labor markets, two societies, and two policy systems.
Ignoring this reality leads to structural problems that no amount of domestic regulation can solve.
1. Migration always links two labor markets
When a worker moves from one country to another, the impact is felt in both places.
The receiving country gains labor.
The sending country loses labor — at least temporarily.
But the story does not end there.
Most foreign workers eventually return home.
When they do, their future depends largely on the opportunities available in their home country’s labor market.
If no such opportunities exist, the migration cycle breaks down.
Workers become reluctant to return, and irregular stay becomes more likely.
In other words, what appears to be an immigration control problem may actually be a labor market problem spanning two countries.
2. The structural cause behind runaway workers
Japan has often treated the issue of runaway workers — particularly under the Technical Intern Training Program — primarily as a problem of supervision or compliance.
But the deeper cause is often economic.
Many workers know that if they return home, they will struggle to find employment that matches their experience or income level in Japan.
This reality creates a powerful incentive to remain abroad, even when the legal framework assumes temporary migration.
If policy design does not take this reality into account, enforcement alone cannot solve the problem.
3. The missing link: post-return employment
For many years, Japan’s foreign worker programs formally emphasized “skills transfer.”
In practice, however, the connection between training in Japan and employment opportunities after return has often been weak.
The new Ikusei Shūrō system has largely abandoned the language of skills transfer.
Yet removing that concept entirely may overlook an important function.
Even if skill transfer is no longer the central objective, a pathway to employment after return remains essential for sustainable migration systems.
Without it, temporary migration risks turning into permanent irregularity.
4. Toward a bilateral migration design
A more sustainable approach would treat foreign worker policy as a bilateral institutional design.
This means coordinating not only immigration rules but also labor market policies between countries.
Examples might include:
- cooperation with industries in sending countries
- certification systems recognized in both countries
- training programs linked to actual job opportunities after return
- partnerships between companies operating in both markets
Such arrangements do not eliminate migration pressures entirely.
But they can stabilize the migration cycle.
5. Migration governance in an interdependent world
In an era of demographic decline, Japan cannot rely solely on domestic policy tools to manage foreign labor.
Migration is part of a broader international system of labor mobility.
Recognizing this reality does not weaken national sovereignty.
Rather, it allows countries to design migration systems that are both realistic and sustainable.
The Balanced Coexistence Model emphasizes exactly this kind of institutional balance.
Foreign workers are not merely labor inputs.
They are participants in a transnational economic and social system.
Policies that acknowledge this interconnectedness are far more likely to succeed than those designed within a single country’s borders.
