1. Japanese Language Requirement for Permanent Residency

Until now, Japan’s permanent residency applications have mainly focused on factors such as:

• Good conduct
• Financial independence and stable income

However, a new policy proposal is considering the introduction of a Japanese language proficiency requirement.

• What may change
  Applicants may be required to demonstrate Japanese language ability sufficient for daily life and social participation — not just long-term residence.

• What you can do
  If you are aiming for permanent residency, starting preparation for exams such as the JLPT (Japanese Language Proficiency Test) early will be a key step toward successfully migrating to Japan.

2. Required Residency Period for Naturalization May Be Extended to 10 Years

For those who wish to acquire Japanese nationality and live as Japanese citizens, this potential change is particularly significant.

• Current requirement: Continuous residence in Japan for at least 5 years
• Proposed change: Extension to 10 years or more

The background to this proposal is the government’s intention to more carefully assess long-term integration into Japanese society.

Naturalization is a major life decision. Staying informed and planning with a long-term perspective is essential.

3. Unpaid Taxes and Social Insurance May Directly Affect Visa Renewal

Another key focus of the proposed policy changes is strict enforcement of public obligations.

Important points

If you have unpaid obligations such as:

• Taxes
• National health insurance premiums
• Other public payments

your visa renewal may be denied.

After achieving “moving to Japan,” the most important thing is to comply with Japan’s rules. Even minor payment delays can have serious consequences for future renewals or permanent residency applications.

4. Stronger Rules, but Expanded Support for Integration

While requirements may become stricter, the Japanese government is also strengthening support to prevent foreign residents from becoming isolated.

• Japanese language support: Expansion of community-based language education programs
• Cultural and lifestyle support: Programs to help foreign residents understand Japanese customs and daily life

These initiatives represent positive steps toward a safer and more inclusive living environment in Japan.
