Important Notes on Part-Time Jobs in Japan for Foreign Workers

Have you ever considered earning extra income through a part-time job in Japan? Although salaries in Japan are generally stable, you might want additional earnings to cover living expenses or enjoy a more comfortable lifestyle.

In this article, HSB JAPAN will help answer questions about taking on a part-time job while having a full-time position and guide you on how to find a suitable job.

1. Can You Work Part-Time in Japan?

The answer is yes, but it depends on the type of work and the regulations set by both your company and the Immigration Services Agency of Japan. Before taking on a part-time job, consider the following:

Check Your Employment Contract and Company Policies

First, review your employment contract and company regulations (shugyo kisoku/就業規則) to determine whether your employer allows part-time work. If permitted, you may need approval from your manager or HR department. If not, taking on a part-time job could violate your contract and even lead to dismissal.

Most companies do not allow employees to work for competitors, as this can impact trust and result in serious consequences.

Check Your Visa Type

Each visa type has different rules regarding part-time work:

• Engineer/Humanities/International Services Visa: You may take on a part-time job if it aligns with your expertise (e.g., programming instruction, specialized writing, translation).
• Highly Skilled Professional Visa: Requires a Work Permit for Activities Outside Visa Status from the Immigration Services Agency before engaging in additional work.

2. What Is a Work Permit for Part-Time Jobs?

A Work Permit for Activities Outside Visa Status (shikakugai katsudo kyoka/資格外活動許可) is an official approval from the Immigration Services Agency that allows you to work outside your primary visa’s scope. To qualify, you must meet the following conditions:

• The part-time job must not interfere with your full-time job.
• Your main employer must approve it.
• You must not work in prohibited industries (bars, nightclubs, pachinko parlors).
• You must not have a criminal record.

There are two types of permits:

• General Work Permit: Allows up to 28 hours per week, commonly issued for students and dependents.
• Specific Work Permit: Issued for jobs outside the primary visa’s scope but within professional fields.

Holders of work visas such as Engineer/Humanities/International Services are not allowed to engage in unskilled jobs such as restaurant service or convenience store cashier work.

3. How to Apply for a Work Permit?

If your part-time job requires a permit, you must prepare the necessary documents and submit them to the Immigration Services Agency. The required documents include:

• Application form (PDF/Excel)
• Employment contract for the part-time job
• Residence card and passport
• Other relevant documents

The processing time can take two weeks to two months, and you must not start working while waiting for approval.

4. How to Find a Part-Time Job in Japan?

If you decide to seek a part-time job, consider the following approaches:

• Use freelance job search apps.
• Look through social media and Vietnamese communities in Japan.
• Network with local communities and attend events to expand your opportunities.

5. Do You Need to File Taxes for a Part-Time Income Under 200,000 Yen?

If your annual part-time income is below 200,000 yen, you are not required to file income tax. However, if you apply for medical tax deductions or hometown tax deductions, you must report this income.

Additionally, resident tax (juminzei/住民税) must be paid regardless of your part-time income level.

Many people mistakenly believe that income under 200,000 yen does not need to be declared. To avoid financial risks, consult a tax expert or a reliable service provider.
