If you were employed in Japan, part of your salary was automatically deducted for Employees’ Pension Insurance (Kōsei Nenkin).

Many people assume this works like a savings account — but in reality, it is a social insurance system with specific conditions.

How Contributions Are Calculated

The amount you pay into the pension system depends on your salary.

This means your total contributions can become quite significant over time.

Why Your Monthly Deduction Changes

Your pension deduction is not fixed forever.

Bonus Payments Are Also Included

Pension contributions are not limited to monthly salary.

What the Pension Actually Covers

Employees’ Pension Insurance is not just for retirement.

Important

These benefits are designed primarily for people who stay in Japan long-term.

When Can You Actually Receive Pension Benefits?

This is where many people misunderstand the system.

Reality check

If you worked in Japan for only a few years, you may never receive any pension payments — unless you take action.

So What Happens If You Don’t Qualify?

If you leave Japan and do not meet the conditions for a pension, your contributions are not automatically returned.

However, there is a solution:

You may be eligible for a lump-sum withdrawal payment, which allows you to recover part of what you paid.

Don’t leave your contributions behind

If you don’t qualify for a Japanese pension, you may be able to claim a refund instead. We handle the full process for you.
