How to Read Your Nenkin Teiki-Bin Statement

Each year, around your birth month, the Japan Pension Service sends an annual statement to enrolled contributors. The envelope is easy to set aside, but the document inside is one of the most useful pieces of paper in your retirement planning. Understanding what it shows, and what it does not, is a practical first step toward knowing where you stand.

What the Statement Actually Contains

The nenkin teiki-bin shows your total number of contribution months to date, split between the national pension and the employees' pension. It also shows an estimated monthly benefit. How that estimate is calculated differs by age group, and the explanatory leaflet that comes with the statement tells you which method applies.

What it does not show is a breakdown of which specific periods are recorded as paid, unpaid, or exempt. For that level of detail, you need to request a full contribution record (被保険者記録照会) from the Japan Pension Service, either at a pension office or through the Nenkin Net online service.

Common Errors Worth Checking

Gaps in the record are among the most common problems people find. They arise for several reasons: a period of self-employment where contributions were not paid, a job change where the new employer was slow to enroll the employee, or a period of residence abroad. Some gaps can be filled retroactively through voluntary contributions, but the window for doing so is limited.

Name and date-of-birth discrepancies also appear occasionally, particularly for people who changed their registered name after marriage. These are worth correcting before you file for your benefit, as they can slow down the processing of your claim.

Using Nenkin Net to Go Deeper

The Japan Pension Service's Nenkin Net portal allows you to view your full contribution record month by month, check your projected benefit under different scenarios, and receive your annual statement digitally rather than by post. Registration needs your basic pension number (基礎年金番号) and either a My Number card or a separate ID verification step; the Japan Pension Service site describes the current options.

For anyone who is more than a few years from retirement, logging into Nenkin Net once a year and checking the record is a straightforward habit that catches errors while there is still time to correct them.

The statement is a starting point, not the whole picture. If anything in yours looks unexpected, you can write to us to ask whether a consultation would help, or ask the Japan Pension Service directly.
