Summary
Japan's public pension system is built around the National Pension and Employees' Pension Insurance. The National Pension is the basic layer for people aged 20 to under 60. The Employees' Pension is an additional layer for company employees, public employees, and some part-time workers.
The easiest way to understand the system is as a two-story structure: National Pension on the first floor, Employees' Pension on the second floor.
The two-story structure
Second floor: Employees' Pension Insurance
First floor: National Pension / Basic Pension| Work style | Main public pension coverage |
|---|---|
| Self-employed, freelancers, students | National Pension |
| Company employees and public employees | National Pension + Employees' Pension |
| Dependent spouses of employees | National Pension |
Employees often think they are only in the Employees' Pension, but they are also covered by the National Pension at the same time.
National Pension
The National Pension is the basic public pension. People aged 20 to under 60 generally enroll.
Typical members include self-employed workers, freelancers, students, people not working, company employees, public employees, and dependent spouses.
| Item | National Pension |
|---|---|
| Position | First floor |
| Premium | Fixed in principle |
| Retirement benefit | Old-age Basic Pension |
| Main issue | Amount may be limited, so additional preparation is often needed |
Employees' Pension
The Employees' Pension is the second-floor public pension for employees and public workers. Premiums are linked to salary and bonuses, and the employer generally pays half.
| Item | Employees' Pension |
|---|---|
| Position | Second floor |
| Premium | Earnings-related |
| Employer contribution | Generally half |
| Retirement benefit | Old-age Employees' Pension added to basic pension |
This is why long-term employees often receive more than people covered only by the National Pension.
Why the pension amount differs
Employees pay earnings-based premiums, and employers also contribute. Over many years, this creates an additional pension amount on top of the basic pension.
Self-employed workers and freelancers mainly rely on the National Pension, so they often need savings, iDeCo, National Pension Fund, or NISA-style investing.

Employees are not in the National Pension
They are. Employees' Pension members are also covered by the National Pension.
Employees receive only the Employees' Pension
In retirement, eligible workers receive both the basic and employee pension portions.
Public pensions are always enough
Depending on rent, care costs, and lifestyle, additional preparation may be needed.
Conclusion
The key difference is whether there is an additional second-floor benefit. The National Pension is the common base. The Employees' Pension adds coverage for employees and public workers.
