Nenkin Teikibin and Nenkin Net Statements

Your pension record arrives through two channels: a paper notice every birth month and an online portal that never closes.1 Foreign residents who learn to read both catch missing employment months years before those months cost them money or paperwork.

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at the Japan Pension Service site. This article is general information, not tax, legal, or immigration advice; for a missing-month or disputed-record case, consult a licensed sharoshi before the claim stage.

Overview​

The Japan Pension Service reports each insured person's record through the yearly ねんきん定期便 (nenkin teikibin, "Pension Coverage Regular Notice") and the always-on 年金ネット (nenkin netto, "Nenkin Net") portal, the two reporting faces of the social insurance system.1 Both draw on the same underlying record: coverage length, anticipated benefit, and contributions paid.1 Either channel can anchor a cross-check; together they make missing months visible.

The paper notice: Nenkin Teikibin​

The Teikibin arrives in the birth month every year with an explanatory brochure (a month early for readers born on the 1st).2 Contents scale with age. Readers under 50, except at milestone ages, see participation months, the estimated benefit on the current record, premiums paid, and the last 13 months of detail.2 The age-35 and age-45 mailings add full participation history, monthly salary status for Employees' Pension, and National Pension payment status.2

From 50 onward the estimate assumes continued participation to 60 on current terms, and adds a lump-sum estimate figure.2 The age-59 mailing is the full pre-retirement set on the same assumption.2 Keep the milestone envelopes; they are the snapshots future disputes reference.

The birth-month pensioner report is a different form

Pensioners without a registered My Number file a separate yearly status report in their birth month, and missing it suspends payment until received.3 That obligation belongs to benefit recipients, not to contributors reading a Teikibin.

The online portal: Nenkin Net​

Nenkin Net has run since February 2011 as the 24-hour window into the same record: coverage history, covered months, benefit-calculation base income, contributions, and payment history.4 Later upgrades added future-benefit estimates under scenarios such as working while receiving or delaying the start, electronic viewing of mailed letters and notices inside the portal, and reissue of tax-deduction slips.14

Access runs through the standard identity rails, with My Number linkage letting the Service confirm registry data for continuing eligibility.3 Readers without home internet can check records at JPS branches and at some municipal offices and post offices.1 A dedicated dial supports Teikibin and Nenkin Net questions specifically.1

Cross-checking your record​

The routine is simple and worth doing yearly. Open the Teikibin or Nenkin Net, walk every employment period since arrival, and confirm each month with the corresponding employer's records.1 Mid-career hires with pre-Japan histories should expect those foreign years to be absent; only Japanese coverage, plus any totalization-counted months, enters the Japanese record.56

One structural blind spot needs stating. Mutual-aid association periods do not appear in Nenkin Net or Teikibin records, so public servants and private-school staff must track those years through the association channel.1 Corrections otherwise run through employer-side records, which is why fixing a missing month gets harder the longer the employer is gone.

Statements as immigration evidence​

The same printouts double as residence paperwork. The Nenkin Net monthly payment status, plus premium receipts for any National Pension months, is the standard pension evidence set for permanent residency applications covering the review window.7 Pull the set before the gyoseishoshi asks for it, reconcile every month, and attach explanations for anything unproducible.7

An unchecked record can sink permanent residency

Reviewers read the same monthly grid you can print at home, and gaps you never noticed read as arrears to them. Reconcile the two-year review window before filing anything with immigration, where pension and tax compliance decide outcomes, and read the compliance entry for the full evidence sequence.

Good to know​

Mutual-aid periods do not appear in these records​

Nenkin Net and the Teikibin exclude mutual-aid association coverage by design.1 Association members who assume one portal shows everything will undercount their own history at claim time.

The age-35, 45, and 59 mailings carry extra detail​

Milestone ages trigger the history and pre-retirement estimate variants.2 Even readers who shred routine mail should file these three; they compress the most verification value per envelope.

Fix missing months while the employer still exists​

Record corrections lean on employer-side evidence, and defunct employers make proof far harder.1 A ten-minute check each birth month beats a reconstruction project at age 64.
