How to Prove Overseas Work Experience for Japan's HSP Points

Can your professional experience outside Japan count toward the Highly Skilled Professional (HSP) points system? What if your former employer cannot issue a detailed employment certificate?

These are common questions from foreign professionals preparing to apply for Japan's Highly Skilled Professional status or permanent residency through the HSP points-based route.

Many applicants have worked for several companies across different countries before moving to Japan. Although they may have substantial professional experience, obtaining acceptable documentation from former employers can be challenging.

At IMS Legal Professional Corporation, we regularly assist foreign professionals with HSP points assessments, employment history reviews, and permanent residency applications.

This article explains how overseas professional experience is evaluated, what documents may be useful, and how to prepare when employment records are incomplete.

1. Does Overseas Work Experience Count Toward HSP Points?

Yes. Relevant professional experience gained outside Japan can count toward the HSP points calculation.

You do not necessarily need to have worked in Japan to claim professional experience points.

However, not every previous job automatically qualifies.

The Immigration Services Agency of Japan evaluates professional experience according to the applicable HSP activity category and the nature of the work performed.

For example, an IT engineer who worked overseas before joining a technology company in Japan may be able to count that experience if the previous duties are relevant to the professional activities being assessed.

Applicants should distinguish between:

• Total years of employment
• Years of relevant professional experience
• Years of experience supported by documentary evidence

These figures are not always identical.

For further information about the HSP points system, please refer to the Immigration Services Agency of Japan's official HSP points information.

2. What Documents Can Prove Overseas Work Experience?

The most useful document is generally a certificate issued by a current or former employer confirming both the employment period and the nature of the work.

A well-prepared employment certificate should ideally include:

1. The employee's full name
2. The employer's name
3. The exact employment start and end dates
4. The employee's position or job title
5. A description of the principal duties and responsibilities
6. The issuing date and information identifying the employer or authorized issuer

Depending on the circumstances, other documents may also help establish the employment relationship or explain the nature of the work.

• Employment contracts
• Appointment or offer letters
• Employer-issued job descriptions
• Promotion or transfer letters
• Other official employment records

Important: These documents should not automatically be assumed to replace an employment certificate. Their sufficiency depends on the information they contain and the circumstances of the application.

3. What if My Employment Certificate Does Not Describe My Job Duties?

This is one of the most common documentation problems encountered by applicants with international careers.

Some employers issue standardized certificates stating only the employee's name, job title, and employment dates.

Although such a certificate may establish the period of employment, it may not adequately demonstrate that the applicant performed work relevant to the HSP category.

For example, a certificate stating that an applicant worked as a "Manager" may not explain whether the position involved software development, engineering, research, business administration, or another type of activity.

Where possible, applicants should request an additional document describing their responsibilities.

This might be a detailed certificate of employment or a separate employer-issued statement.

If obtaining such a document is difficult, the available records should be reviewed before deciding whether additional evidence may be necessary.

The important question is not simply whether you worked for the company, but whether the documents establish the professional experience for which you are claiming points.

4. What if My Former Employer Has Closed or Will Not Issue a Certificate?

Obtaining employment records can be particularly difficult when an applicant worked overseas many years ago.

Common situations include:

• The former employer has closed permanently.
• The company has merged or changed its name.
• The human resources department cannot access old records.
• The employer issues only a basic employment verification letter.
• The applicant no longer has contact with former supervisors.

In these circumstances, applicants should first collect whatever reliable records remain available.

These are examples of potentially useful supplementary evidence, not a guaranteed list of acceptable substitutes.

The Immigration Services Agency may request further clarification or additional documents.

5. Do Gaps Between Jobs Affect HSP Points?

A gap between two jobs does not necessarily invalidate the professional experience gained before or after the gap.

However, applicants should not count periods during which they were not engaged in qualifying professional work as though they were periods of employment.

Consider the following example:

The employment gap should be identified rather than included in the total qualifying experience.

Applicants should calculate their professional experience using exact dates, not rounded estimates.

This is particularly important when the total is close to a threshold in the HSP points table.

6. Does Part-Time Employment Count Toward HSP Professional Experience?

Part-time employment requires careful individual assessment.

The relevant questions include the actual duties performed, contractual arrangements, employment period, and whether the experience qualifies under the applicable HSP category.

Applicants should not assume that every part-time job counts in full simply because it involved professional duties.

Similarly, they should not automatically exclude a period without reviewing its circumstances.

If your employment history includes part-time contracts, changes from part-time to full-time employment, or overlapping jobs, it is advisable to have the documents reviewed before finalizing the points calculation.

7. Can I Use Overseas Experience When Applying for Permanent Residency?

Yes. Relevant overseas experience may also be important when applying for permanent residency through the HSP points-based route.

Depending on the route, applicants may need to demonstrate that they satisfied the required HSP points threshold at both the current assessment date and a specified date in the past.

• 80 points or more: A preferential permanent residency route involving a shortened residence requirement of one year, subject to the applicable conditions.
• 70 points or more: A preferential permanent residency route involving a shortened residence requirement of three years, subject to the applicable conditions.

Applicants should not assume that their current points automatically establish their historical points.

Professional experience, salary, age, and other scoring factors may differ between the relevant assessment dates.

An applicant who has enough points today may still need additional documentation to establish the required score one or three years earlier.

Holding Highly Skilled Professional residence status itself is not necessarily required in every case to apply for permanent residency using the points-based preferential route.

Eligibility depends on the applicable requirements and the applicant's immigration history.

8. What if I Cannot Prove All My Claimed Work Experience?

If the available documents do not adequately establish a particular period of professional experience, the Immigration Services Agency may decline to award the points claimed for that period.

This can be particularly important when an applicant's score is close to 70 or 80 points.

For example, an applicant who calculates 80 points but cannot substantiate part of their professional experience may fall below the required threshold.

Therefore, we recommend reviewing supporting documents before relying on a particular score to determine permanent residency eligibility.

In some cases, an applicant may still have sufficient points without claiming every period of employment.

In other cases, obtaining additional evidence or reconsidering the application timing may be necessary.

9. Practical Checklist Before Applying

• Have you listed all employers and exact employment dates?
• Have you identified which positions are relevant to your HSP activity category?
• Do your employment certificates describe your duties, not just your job titles?
• Are there any unexplained gaps or overlapping employment periods?
• Can you document overseas employment that ended several years ago?
• Have you calculated your experience at each required assessment date?
• Have you checked whether your points remain sufficient if any claimed period is excluded?

Preparing these details early can help identify documentary weaknesses before the application is submitted.

10. Frequently Asked Questions

Can I count work experience from multiple countries?

Yes. Relevant professional experience from different countries may be considered, provided the periods and nature of the work can be adequately established.

Can I use an employment contract instead of a certificate of employment?

An employment contract may be useful supporting evidence. However, it may not establish the actual duration of employment or all duties performed. Whether it is sufficient must be assessed individually.

Do I need employment certificates from every previous company?

You should obtain adequate evidence for the employment periods you intend to claim. If you do not need points from certain periods, the documentary requirements may differ.

Can I count work experience that is unrelated to my current profession?

Not necessarily. The professional experience must satisfy the requirements of the relevant HSP category. Unrelated employment should not automatically be included.

What happens if my former employer refuses to cooperate?

You can review other available employment records and consider whether additional evidence can be obtained. However, alternative documents are not guaranteed to be accepted.

Can I submit additional employment evidence after filing?

Immigration may request or accept supplementary documentation during examination, depending on the circumstances. However, applicants should not rely on later submissions to establish facts or eligibility that did not exist at the relevant assessment date.

Conclusion: Documentation Matters as Much as Your Experience

Having extensive professional experience does not necessarily mean that all of it will be recognized for HSP points purposes.

For applicants with international careers, the main challenge is often proving the relevant employment periods and professional duties through reliable documentation.

This is especially important for permanent residency applications where even a small difference in the accepted points can affect eligibility.
