I. Overview of the Pension System Reform Bill and Implementation Dates

According to the official website of the Ministry of Health, Labour and Welfare, the proposed amendments cover a wide range of areas, with the main points outlined as follows:

1. Expansion of social insurance coverage (removal of the 1.06 million yen income cap)
2. Revision of the in-employment old-age pension system
3. Changes to the survivor’s pension system
4. Increase in the wage cap used to calculate premiums and pension amounts
5. Revision of the child addition benefit

It’s important to note that each of these changes has a different scheduled implementation date.

Regarding the purpose of the reform, the Ministry explains:
“The aim is to strengthen the functions of the pension system in light of social and economic changes by creating a system that is neutral to working styles and gender differences, and responsive to the diversification of lifestyles and family structures. At the same time, the reform seeks to ensure financial stability in old age through enhanced income redistribution and the expansion of private pension systems.”

1. Expansion of Social Insurance Coverage (Removal of the 1.06 Million Yen Income Cap)

The government is reviewing the eligibility requirements for enrollment in Employees’ Pension Insurance and Health Insurance for part-time workers at small and medium-sized enterprises and for those working at sole proprietorships.

Until now, the conditions for part-time and short-hour workers to join social insurance included prescribed weekly working hours, monthly wages of 88,000 yen or more, employment at companies with more than 50 employees, and not being a student.

Under the current revision, these requirements will be simplified.

Specifically, the “wage requirement” (monthly earnings of 88,000 yen or more) will be abolished. This change responds to concerns over the so-called “1.06 million yen annual income barrier.” The timing of enforcement will be decided by a government ordinance within three years after the law is promulgated, based on the situation of regional minimum wage increases across the country.

In other words, once the wage requirement is removed, anyone working 20 hours or more per week will be eligible for social insurance coverage. However, since minimum wages continue to rise, trying to earn less than 88,000 yen per month while working 20 hours or more would mean earning an hourly wage of 1,015 yen or less. Considering ongoing minimum wage increases, this effectively means the wage requirement has already been practically abolished.

Next, the company size requirement will be gradually eliminated. Currently, only part-time workers at companies above a certain size are eligible for social insurance. This will be phased out over 10 years, so that ultimately, part-time workers who work 20 hours or more per week will be covered regardless of their employer’s size.

The eligibility expansion schedule is as follows:

• Companies with 36 to 50 employees: from October 2027

• Companies with 21 to 35 employees: from October 2029

• Companies with 11 to 20 employees: from October 2032

• Companies with 10 or fewer employees: from October 2035

Additionally, the scope of sole proprietorships required to enroll in social insurance will be broadened.

Currently, only sole proprietorships employing five or more people in 17 legally designated industries are subject to social insurance. From October 2029, in principle, all sole proprietorships employing five or more people will be subject to coverage, regardless of industry.

However, transitional measures will exclude existing businesses at the time of enforcement in October 2029 for a certain period.

Support measures for newly covered individuals and employers are also being considered, but it should be noted that these may be temporary.

As support for employers, a program is being considered to provide career advancement subsidies (up to 750,000 yen per employee) to those who increase employee income through longer working hours or wage raises. This is planned for implementation within fiscal 2025.

For workers, a special, temporary transitional measure will be introduced to reduce their insurance premium burden to a government-set ratio for three years, aiming to reduce adjustments in working hours to avoid insurance costs.

2. Revision of the In-Employment Old-Age Pension System

With the increasing number of elderly people working while receiving pensions and to address labor shortages, the government will revise the in-employment old-age pension system.

The in-employment old-age pension system reduces pension payments for elderly workers who earn a certain level of wages. Under the current system, if the combined amount of an elderly worker’s monthly wages (including one-twelfth of annual bonuses) and their Employees’ Pension exceeds 500,000 yen, half of the excess amount is deducted (pension payment is reduced).

Under the proposed revision, the income threshold for pension reduction will be raised from the current 500,000 yen to 620,000 yen. This new threshold is designed with the assumption of individuals who continue working while receiving a pension and earn wages comparable to the average salary of people in their 50s.

This revision is scheduled to take effect from April 2026.

3. Revision of the Survivor’s Pension

The survivor’s pension is a pension received by surviving family members when a person insured under the Employees’ Pension Insurance or the National Pension system passes away. There are two types of survivor’s pensions: the Basic Survivor’s Pension (遺族基礎年金) and the Employees’ Survivor’s Pension (遺族厚生年金), which differ in eligibility requirements and who qualifies as a beneficiary.

The main goal of revising the Employees’ Survivor’s Pension is to eliminate gender disparities. Under the current system, there were differences between men and women regarding the eligibility conditions and benefit periods for spouses without children to receive the Employees’ Survivor’s Pension.

Under the revised system, spouses without children who are under 60 years old (wives or husbands between the ages of 20 and 50 without children under 18) will generally be eligible for a fixed-term benefit for five years. Additionally, men under 55 without children, who were previously excluded, will become newly eligible.

The system will also consider fixed-term beneficiaries by, for example, increasing old-age Employees’ Pension benefits through death-related pension division and introducing a new fixed-term benefit supplement. The income requirement will be removed, allowing recipients to receive benefits regardless of their earnings.

If necessary, there will be mechanisms to continue benefits beyond the five-year period. Those who already have the right to receive benefits, elderly people aged 60 or older, and spouses aged 20 to 50 with children under 18 will maintain their current benefit conditions. These changes will be phased in over 20 years starting from April 2028.

Regarding the Basic Survivor’s Pension, it will be revised so that children can receive benefits regardless of the circumstances of the caregiver.

This means that children eligible for the Basic Survivor’s Pension will be able to receive it without being affected by factors such as the remarriage of the surviving parent, the parent’s income exceeding the threshold, the child being adopted by a direct relative or similar, or the child being taken in by a former spouse after the parent’s death.

4. Raising the Wage Cap Used for Calculating Insurance Premiums and Pension Amounts

In the Employees’ Pension Insurance system, insurance premiums and pension amounts are basically calculated based on wages (remuneration). However, there is an upper limit set on the “standard monthly remuneration” used as the basis for these calculations.

Currently, the upper limit for the standard monthly remuneration is 650,000 yen. For those earning wages above this limit, the effective insurance premium rate relative to their actual wages has been lower.

The Ministry of Health, Labour and Welfare explains the purpose of this revision as: “to ensure contributions are made in accordance with wages and to enhance future pension benefits.”

Specifically, the upper limit of the standard monthly remuneration will be raised in stages. It will increase from the current 650,000 yen to 680,000 yen (starting September 2027), then 710,000 yen (September 2028), and finally 750,000 yen (September 2029).

While insurance premiums for individuals and companies falling under the new upper limits will increase, future pension benefits will also rise accordingly.

5. Revision of the Child Addition

The pension system includes a provision to increase the pension amount for pension recipients who are raising children. Under the current system, pension recipients with children already receive this addition, but the upcoming revision will raise the amount of the child addition.

Currently, based on the fiscal year 2024 annual amounts, the addition is 234,800 yen per year for the first and second child, and 78,300 yen per year for the third child and beyond. After the revision, the addition will be a uniform 281,700 yen per year for each child. This increase will apply also to those who are currently receiving pensions.

In addition, people who currently receive only the old-age basic pension, which did not include a child addition, will also become eligible for this addition. These revisions are scheduled to take effect from April 2028.

II. Other Major Revisions

In addition to the main revisions mentioned above, there are several other changes.

1. Revision of the Private Pension System

Regarding the individual-type defined contribution pension plan (iDeCo), under the current system, only National Pension insured persons who are not yet receiving the old-age basic pension or old-age benefits from iDeCo can join. Due to differences in working styles, there are variations in the upper age limits for joining.

To create a simpler and more understandable system, the eligibility requirements will be expanded. Specifically, the revision plans to allow people aged 60 and over but under 70—who wish to continue using iDeCo for building retirement assets and who are not yet receiving the old-age basic pension or iDeCo old-age benefits—to join or continue contributions to iDeCo.

2. Revision of the Lump-sum Withdrawal Payment System

The Lump-sum Withdrawal Payment system is designed with the specific circumstances of foreigners in mind, who often have short stays in Japan and whose insurance premium payments may not easily lead to receiving old-age pension benefits. The payment is made as a lump sum based on the insured period (with a current maximum payment period of 5 years), and receiving this payment cancels the insured period accrued up to that point.

However, considering the trend of longer stays by foreigners, there is discussion about raising the maximum payment period from the current 5 years to 8 years. Additionally, for foreigners who may spend their old age in Japan, if they leave the country with a re-entry permit, they will not be able to claim the Lump-sum Withdrawal Payment during the validity period of that permit.

3. Allowing Deferment of Old-Age Pension for Survivors’ Employees’ Pension Recipients

Until now, people receiving survivors’ employees’ pension (遺族厚生年金) were not allowed to defer the receipt of their own old-age pension. However, considering the increased employment of elderly people and from the perspective of allowing them the option to increase their pension benefits, it is planned to permit survivors’ employees’ pension recipients to apply for deferment of their old-age pension benefits. This revision is scheduled to be implemented in April 2028.

4. Extension of the National Pension Payment Deferral System

Until June 2030, eligibility for the deferral system has been determined based on the income of the individual and their spouse, regardless of the income of the household head they live with. This system allows for the deferred payments to be made later when the individual is actually able to pay the insurance premiums.

This time, the limited-time measure will be extended for an additional five years, allowing use of the system until June 2035.

5. Expansion of Eligibility for Voluntary Enrollment in the National Pension for Older Adults

For those without entitlement to the old-age basic pension, the system allowing voluntary enrollment in the National Pension after age 65 until the required qualification period is met will be expanded. The eligible birthdate range will be extended to include people born up to April 1, 1975, and the system will be extended accordingly.

6. Extension of the Deadline for Requesting Division of Pension Rights at Divorce

The deadline for requesting division of the Employees’ Pension Insurance records at the time of divorce will be extended from 2 years to 5 years. This change is in line with the extension of the statute of limitations for property division claims under civil law.
