“I’m enrolled in a defined contribution (DC) or defined benefit (DB) pension plan to save for retirement, but when exactly do I start receiving payments, and how long will they last?”

1. Japan’s Pension System and the Role of DC and DB
Japan’s pension system is often likened to a “three-tiered” structure.
- Tier 1: National Pension (Basic Pension)
- Tier 2: Employees’ Pension (for company employees, civil servants, etc.)
- Tier 3: Private Pensions (DC, DB, etc.)
The DC (Defined Contribution) and DB (Defined Benefit) pension plans discussed here fall under this “third tier.”
They serve as a supplementary mechanism to complement public pensions (first and second tiers) and help ensure a more comfortable retirement.
While public pensions are generally payable starting at age 65, private pensions in the third tier are characterized by flexibility in the timing and duration of benefit payments, depending on the specific plan.
2. When Do Old-Age Benefits Begin?
One of the greatest advantages of private pensions is the option to start receiving benefits earlier (or later) than with public pensions.
For iDeCo (Individual-Type DC) and Corporate-Type DC
A DC (Defined Contribution Pension) is a system in which you invest contributions made by yourself or your employer, and receive the returns on those investments in the future.
- Timing of Benefit Commencement
In principle, you can begin receiving benefits at any time between the ages of 60 and 75, according to your preference. - If You Continue Working After Age 60
If you continue to pay contributions as an insured person (i.e., continue working) after turning 60, it is common practice not to start receiving benefits immediately, but to begin receiving them after losing eligibility (such as upon retirement). - Benefits of Delaying the Start of Benefits
Since you can delay receiving benefits until age 75, you can continue investing your funds during that time or adjust the timing of your benefits based on your other income.
In the Case of a DB (Defined Benefit Corporate Pension) Plan
A DB plan is a system in which the amount of benefits you will receive in the future is predetermined based on factors such as years of service and job title.
The start date for receiving benefits is determined by your employer’s “regulations.”
Typical examples are as follows.
- Retirement at age 60 (with 20 or more years of membership)
Generally, you can begin receiving benefits immediately upon reaching age 60. - Early Retirement Before Age 60 (20 or More Years of Membership)
Even if you retire early, as long as you meet the eligibility requirements (membership period), you will generally begin receiving benefits at age 60. - When the Mandatory Retirement Age Is 65
If your company’s mandatory retirement age is 65, you will generally begin receiving benefits at age 65.
However, depending on the terms of your plan, you may be able to choose to receive benefits early, starting at age 60.
3. How long is the “benefit period” for old-age benefits?
The benefit period—that is, “how many years you will receive the pension you’ve worked so hard to accumulate”—is also a key factor that influences your cash flow in retirement.
For iDeCo (Individual-Type Defined Contribution) and Corporate-Type Defined Contribution Plans
In most cases, the benefit period for a defined contribution plan is set by the individual as a “fixed-term annuity.”
- Setting the Term
Generally, the term is set between 5 and 20 years. - Term Intervals
While this varies by the administering institution (such as a bank or securities firm), it is customary to be able to select terms in one-year increments. - Flexibility in Choice
The beneficiary can choose the term based on their personal circumstances, such as “receiving payments concentrated over 10 years to coincide with the full repayment of a mortgage” or “receiving payments over the five years leading up to the start of public pension benefits.”
In the case of a DB (Defined Benefit Corporate Pension)
For a DB plan, you will select your benefit payment period from a set of predefined options.
- Fixed-Term Annuities
These are annuities that provide payments for a fixed period, such as a “10-year fixed-term annuity,” “15-year fixed-term annuity,” or “20-year fixed-term annuity.” - Lifetime Annuities
These are annuities that provide payments for the rest of your life. - Differences by Plan
The available payment periods vary depending on the defined benefit (DB) plan rules of the company you were employed by.
In some cases, only a lifetime annuity is available, while in others, you may choose from multiple payment periods.
Benefits from the Corporate Pension Federation
If you transfer your pension assets to the Corporate Pension Federation (using the portability system) due to early retirement or similar circumstances, the rules for receiving benefits are slightly different.
- Payment Structure
As a general rule, payments are made as a lifetime annuity, similar to public pensions. - Restrictions
Unlike standard corporate pension plans (such as defined contribution or defined benefit plans for current employees), you cannot defer the start of payments.

We have summarized the differences between the two plans in a table.
| Item | iDeCo・Employer-Sponsored Defined Contribution Plan | DB (Defined Benefit Corporate Pension Plan) | Corporate Pension Federation |
| Effective Date of Benefits | Optional for ages 60 to 75 | As specified in the regulations (generally age 60, etc.) | Generally, age 65 (same as the public pension system) |
| Benefit period | 5 to 20 years (optional) | Fixed-term annuity (10–20 years) or lifetime | Lifetime Annuity |
| decision-making authority | Decided at the individual’s request | In accordance with the regulations | as required |
| postponement | Available (up to age 75) | This may be permitted under the terms of service | Not allowed |
5. Key Points to Check in Your Personal Pension Plan to Avoid Mistakes
The details of private pension plans vary significantly depending on your employer and the financial institution you choose.
When planning for your retirement, be sure to check the following points.
- Check the Terms and Conditions
Be sure to review your employer’s employee benefits website or any handouts provided.
Defined Benefit (DB) plans, in particular, tend to have strict company-specific rules. - Check Your Enrollment Period
For DB plans, there may be requirements such as “20 years of enrollment” to qualify for benefits.
Those considering leaving their job mid-career should pay special attention to this. - Run a Benefit Simulation
For Defined Contribution (DC) plans, use the plan administrator’s website; for DB plans, use your company’s pension portal to estimate your future benefit amounts.
Summary: Choosing a Payout Method That Fits Your Life Plan
Defined Contribution (DC) and Defined Benefit (DB) plans are powerful tools for supplementing retirement living expenses, which public pensions alone often fail to cover.
The appeal of DC plans lies in the flexibility they offer: between the ages of 60 and 75, you can freely decide “when to start” and “over how many years” to receive your benefits, tailoring them to your lifestyle.
DB plans offer the reassurance of “lifetime” benefits, depending on the plan, as well as stable payments timed to coincide with retirement.
The key is to accurately understand which plan you are enrolled in and what options are available to you.
Review the terms and conditions of your plan and consult with your provider to ensure you are on track to prepare for your ideal retirement.
