If you are an international student or a foreign resident in Japan aged 20 to 59, you are legally required to enroll in the National Pension system. Fortunately, if you have a low income or are currently studying, you can apply for a student payment postponement or contribution exemption to avoid financial strain. This guide explains how to register, apply for exemptions, and transition your pension status when you start working in 2026.
Who must enroll in the Japan National Pension system?
Under Japanese law, all residents between 20 and 59, regardless of nationality, must enroll in the National Pension system. This public pension provides basic benefits for old age, disability, and death.
When you move to Japan, you are categorized into one of three types of insured persons:
- Category I: This includes self-employed individuals, students, agricultural workers, and unemployed persons aged 20 to 59 who do not fall under Category II or III.
- Category II: This covers company employees and public sector workers under the age of 70 who are enrolled in the Employees’ Pension Insurance (EPI) system.
- Category III: This applies to economically-dependent spouses of Category II insured persons, aged 20 to 59, who reside in Japan.
If you are moving into Japan, you must be covered as a Category I insured person for the period from your entry until you transition to Category II or III. You must register yourself at the municipal office of your place of residence within 14 days of becoming subject to Category I by submitting the "Application to Enroll in National Pension as Category I Insured Person."
Foreign nationals on specific visas (like medical stays or long sightseeing stays) are exempt. For individual eligibility, confirm directly with your local municipal office or the Japan Pension Service.
How does the Special Payment System for Students work?
If you are an international student with an income below a certain limit, you can apply for the Special Payment System for Students to postpone your contribution payments.
Here is what you need to know about this student postponement:
- Application Process: You must apply for this postponement at the municipal office where you live. Each application covers up to one year, meaning you must reapply every year if you remain a student.
- Pension Validity: The period during which your postponement is approved is considered a valid period, not a period of non-payment.
- Disability and Survivors' Benefits: If you experience a disability or pass away during this approved period, you or your survivors may still receive the Disability or Survivors' Basic Pension. To qualify, you must have filled at least two-thirds of your insured period with paid or exempted months by the second month before the incident, or you must have paid or been exempted for the last 12 months leading up to that second month.
- Impact on Old-Age Pension: While these postponed periods count toward the qualifying period required to receive your future Old-age Basic Pension, they will not be factored into the final calculation of your pension benefit amount unless you pay them back later.
What are the pension contribution exemption options in 2026?
If you are not a student but still face temporary financial difficulties, you can apply for a general contribution exemption or postponement. Approval is based on the previous year's income of yourself, your spouse, or your household head.
For the fiscal year 2026, the available exemption tiers and the remaining monthly amounts you must pay are:
- Full-amount exemption: You pay \0.
- 3/4-amount exemption: You pay the remaining \4,480 per month.
- Half-amount exemption: You pay the remaining \8,960 per month.
- 1/4-amount exemption: You pay the remaining \13,440 per month.
It is critical to pay the remaining portion of your partial exemption. If you fail to pay the remaining due amount, the entire period will be treated as non-payment rather than a partial exemption.
These exempted periods still count toward your pension calculation, but at a reduced rate. For periods from April 2009 onward, the calculations are as follows:
- A full-amount exemption period counts as 1/2 of a full-contribution-paid period.
- A 3/4-amount exemption period counts as 5/8.
- A half-amount exemption period counts as 6/8.
- A 1/4-amount exemption period counts as 7/8.
Like the student system, you must apply for these exemptions at your local municipal office, and each application covers up to one year.
Can I pay back my postponed or exempted contributions later?
Yes, you can recover your past contribution-exempted or postponed periods by making retroactive payments. This allows you to increase your future Old-age Basic Pension amount.
The rules for retroactive payments include:
- 10-Year Limit: You can make retroactive payments for up to the past 10 years.
- Indexing: If you recover contributions three or more fiscal years after the exemption was granted, a specific index rate will be added to your past contribution amount based on how old the contribution is.
- How to Pay: You must contact your nearest Japan Pension Service (JPS) branch office to arrange these payments. It is highly recommended to apply well in advance, as payments submitted right before the deadline might not be processed in time.
What happens to my pension when I start working?
When you graduate and secure a job in Japan, your pension status will change. Your employer will enroll you in the Employees’ Pension Insurance (EPI) system. Once enrolled, you automatically become a Category II insured person under the National Pension system, and your employer will handle the registration. You do not need to perform any extra procedures yourself. Note that you must be covered under Category I from your entry into Japan until you transition to Category II or III.
Finding a place to stay
Before you can register for the National Pension, you must establish a registered address in Japan. It is highly recommended to secure your accommodation after your visa is approved and before you land. Many newcomers stay in a furnished monthly apartment first to settle in quickly. OHAYO Stay offers furnished monthly apartments and rooms in Tokyo; most homes have a minimum stay of 30 nights (shown on each listing). The monthly price includes electricity, gas, water and Wi-Fi. No guarantor, no key money and no agency fee; booking is online with a passport or ID and a credit card. Having your housing secured beforehand ensures you can complete your municipal registration and pension application smoothly within your first 14 days.
