Introduction
Japan has introduced a new requirement(Japan to require language proficiency proof for engineer, specialist visa KYODO NEWS 2026-04-04):
Applicants for the status of Engineer/Specialist in Humanities/International Services may now be required to demonstrate Japanese language proficiency at approximately the B2 level (equivalent to JLPT N2), particularly for roles that require Japanese.
At first glance, this appears to be a reasonable tightening of standards.
After all, language ability is closely tied to job performance and workplace integration.
However, within the framework of the Balanced Coexistence Model, the key question is not whether language requirements are justified.
The question is how they function within the system.
Are they a tool for integration?
Or are they becoming a substitute for addressing deeper structural problems?
The Background: A Response to System Abuse
The policy revision is clearly a response to a growing issue.
Individuals entering under a status intended for skilled work have, in some cases, been employed in unskilled or unrelated roles.
This represents not merely individual misconduct, but a structural distortion:
- Employers misclassify job roles
- Oversight is uneven
- The system relies heavily on ex-post verification
In this context, requiring higher Japanese proficiency seems like a rational filter.
If a job truly requires Japanese, then language ability should align with that requirement.
Language as a Proxy for Compliance
However, the introduction of a language requirement risks turning language into a proxy indicator for something else: compliance.
Instead of directly verifying whether:
- the job content matches the visa category
- the employment conditions are appropriate
- the employer is acting lawfully
the system may begin to rely on language ability as a shortcut.
This creates a structural shift:
from verifying reality → to screening profiles
While efficient, this shift can be misleading.
A person with high Japanese proficiency can still be placed in inappropriate work.
Conversely, a person with lower proficiency may still be performing legitimate, specialized tasks.
The “Cat-and-Mouse” Problem
There is also a dynamic risk.
Employers may respond strategically:
- Redefining jobs as “non-Japanese-required” roles
- Structuring tasks to formally avoid language dependency
- Continuing questionable practices under a different label
In other words, the introduction of a language requirement may not eliminate the underlying problem.
It may simply shift its form.
This is a classic “cat-and-mouse” dynamic between regulation and circumvention.
Alignment with the Balanced Coexistence Model
The Balanced Coexistence Model does not reject language requirements.
On the contrary, it recognizes that language plays a crucial role in social integration.
However, the model imposes a critical condition:
Language requirements must function as part of an integration infrastructure, not as a gatekeeping shortcut.
This means:
- Language ability should be connected to actual social and professional participation
- The state should provide accessible pathways to acquire language skills
- Evaluation should be continuous and context-sensitive, not one-time and rigid
If these conditions are met, language becomes a bridge.
If not, it becomes a barrier.
What Should Be Verified Instead
From the perspective of system design, the core issue lies elsewhere.
What truly needs to be verified is:
- The consistency between job description and actual work
- The integrity of employer behavior
- The continuity and stability of the individual’s employment and residence
These are harder to measure than language ability.
But they are also far more directly linked to the purpose of the status.
Replacing these checks with language thresholds risks misaligning the system.
Toward Explainable and Observable Employment
A more sustainable approach would be to enhance observability in the system.
This could include:
- Better documentation of job content
- Data linkage between employment records and immigration status
- API-based verification mechanisms across institutions
In such a system, compliance is not inferred indirectly.
It is observed directly.
Language ability can still play a role—but as one component among many, not the central filter.
Conclusion
The introduction of a Japanese language requirement reflects a legitimate concern.
But its effectiveness depends entirely on how it is positioned within the system.
If used as a shortcut, it risks masking deeper structural issues.
If embedded within a broader integration infrastructure, it can strengthen both trust and functionality.
The Balanced Coexistence Model reminds us:
Immigration policy should not rely on proxies.
It should be built on systems that make reality visible.
Language, in this sense, should not decide who is allowed in.
It should help determine how people can belong.
