Check Your Japan Pension Record on Nenkin Net

Last updated: 19 October 2026 · the Japan Pension Service’s pages

Your Japanese pension record — every month you were covered, with which scheme, and the pension it adds up to so far — is online in Nenkin Net (ねんきんネット), the Japan Pension Service’s own site. There are two ways in: through the My Number portal (マイナポータル) with a My Number card, or with a Nenkin Net user ID from your Basic Pension Number. The same record also comes by post once a year in your birthday month, as the pension statement (ねんきん定期便). What you pay each month is on your payslip and in the take-home calculator; how the system works is in the pension guide.

This is a general explanation. The Japan Pension Service is the authority on your record, and it handles corrections.

Two ways in

• Through the My Number portal. With a My Number card and an email address, you link the portal to Nenkin Net and open it from there. No separate Nenkin Net user ID is needed.
• With a Nenkin Net user ID. You need your Basic Pension Number (基礎年金番号) and an email address. If you have the 17-digit access key (アクセスキー) printed on a recent pension statement, the ID is issued at once; without it, the Japan Pension Service sends the ID to your address by post, so it takes some days.

Both run on a computer or a phone, and the Japan Pension Service has a chatbot for Nenkin Net that answers around the clock. The screens are in Japanese, so the Japanese names in this page are the ones to look for.

What you can see

• Your record (年金記録): each month of cover, under employees’ pension (厚生年金) with each employer, or under the national pension (国民年金) and whether it was paid, exempted or missed.
• Your estimated pension (年金見込額): what the record adds up to, and what it would come to if you went on paying in on assumptions you choose.
• The pension statement in electronic form, and notices the Japan Pension Service has sent you.

The pension statement by post

Everybody covered receives the pension statement (ねんきん定期便) once a year, in their birthday month. Most years it is a postcard with the recent record and an estimate. At 35, 45 and 59 it comes in an envelope with the whole history, month by month, which is the moment to read it through. A recent statement also carries the access key for a Nenkin Net user ID.

What to check

• Every employer is there. Each job should show as months of employees’ pension. A missing employer, or months under a different name or reading of your name, is worth raising.
• The gaps between jobs. A month between two employers is national pension unless a spouse’s employee pension covered you. Unpaid months show as unpaid; an exemption shows as exempted, at a reduced value.
• The ten-year line. A Japanese old-age pension needs ten years of cover in all. If you might leave Japan before that, the record tells you how far you are — the refund if you leave explains the alternative.

If something is wrong, contact the Japan Pension Service or a pension office (年金事務所) with your payslips or the employer’s details.

Questions people ask

Do I need a My Number card to use Nenkin Net?

No. The card lets you go in through the My Number portal without a separate ID, but you can also get a Nenkin Net user ID with your Basic Pension Number and an email address.

Where do I find my Basic Pension Number?

On your Basic Pension Number notice (基礎年金番号通知書), a blue pension book, or national pension payment slips. With a My Number card, the My Number portal shows it too. Otherwise call the Japan Pension Service’s statement line with your annual pension statement to hand, and it posts you a document with the number; it does not give the number by phone or email.

My years in another country are not in the record. Is something wrong?

No. Nenkin Net shows only Japanese pension cover. Periods in a country whose social security agreement with Japan adds periods together count towards the ten-year line only when you claim; the agreements with the United Kingdom, South Korea, China and Italy do not add periods together at all.
