Quick Answer
This is the ねんきん定期便 (Nenkin Teikibin) — an annual pension record notice sent every year (usually in your birthday month) by the Japan Pension Service (日本年金機構, Nihon Nenkin Kikō). It lets you confirm your pension enrollment records (加入記録, kanyū kiroku) and your estimated future pension amount, the 年金見込額 (nenkin mikomigaku). It is a record-confirmation notice, not a bill and not a payment demand. If anything in the records looks wrong, you can check with a pension office (年金事務所, nenkin jimusho) or verify online via Nenkin Net (ねんきんネット), the online pension record service.
What This Document Is
The Nenkin Teikibin summarizes your enrollment and payment status so far in Japan's public pension system (公的年金, kōteki nenkin) — the National Pension (国民年金, Kokumin Nenkin) and Employees' Pension Insurance (厚生年金, Kōsei Nenkin). Typical contents:
- Enrollment records — months enrolled and the premium payment status for each period.
- Total premiums paid (保険料納付額, hokenryō nōfugaku) — the cumulative premiums you have paid.
- Estimated pension amount (年金見込額) — an estimate of the pension you may receive in the future (presented differently for people aged 50 and over versus under 50).
It is different from payment reminder letters (催告状, saikokujō / 督促状, tokusokujō), which alert you to unpaid premiums.

What You Need to Do
- Check that the enrollment period (加入期間) and total premiums paid (保険料納付額) match your actual work and payment history.
- Look at the estimated pension amount (年金見込額) for a sense of your future pension (a reference figure only — it changes with your future payments).
- Use Nenkin Net (ねんきんネット) to check more detailed records online at any time.
- If you find gaps or errors in the records, take the Teikibin to a pension office (年金事務所) to confirm and request a correction.
Possible Deadlines / Where the Amounts Are
- Deadline — the Teikibin itself carries no payment deadline; it is a record-confirmation notice.
- Amounts — see 保険料納付額 for your cumulative payments and 年金見込額 for the future estimate; in all cases the Japan Pension Service's records are authoritative.
Which Official Body to Check With When Unsure
For records, estimated amounts, and corrections, follow the explanations of the Japan Pension Service (日本年金機構) and your nearest pension office (年金事務所); you can also confirm online via Nenkin Net (ねんきんネット). Official explanations take precedence over any third-party interpretation.
