Nenkin Net is the Japan Pension Service’s online view of your pension record. For many foreign residents, the practical problem is not what the record shows but how to sign in after leaving Japan. Your My Number card is normally returned when you move abroad, and a user ID sent by post can take days to arrive. Set up a route that will still work once you are gone.
Information checked October 1, 2026. This guide summarizes Japan Pension Service (JPS) guidance on registration and login. It does not cover every screen, and procedures can change. Use the official pages linked below when you register.
Two ways to sign in
The JPS login page (Japanese) describes two routes:
- Mynaportal. Sign in to Mynaportal with a My Number card, then open Nenkin Net from the pension menu. No separate Nenkin Net user ID is needed.
- Nenkin Net user ID. Sign in on the JPS website with a user ID and password issued for Nenkin Net.
According to the JPS registration overview (Japanese), the Mynaportal route needs a My Number card and an email address. The user ID route needs your Basic Pension Number and an email address.
Why foreign residents should get a user ID
If you are a foreign resident, your My Number card is normally returned with your overseas moving-out notification. The Mynaportal FAQ says that using Mynaportal after moving abroad requires the overseas version of the card, which is designed for Japanese nationals.
So, even if you already use Nenkin Net through Mynaportal, consider getting a user ID while you are still in Japan. It gives you a sign-in route that does not depend on the card.
Registering with an access key: immediate issue
An access key is a 17-digit number. The JPS access key FAQ (Japanese) says it is provided in the "Nenkin Teikibin" (pension record statement) or issued at a pension office. With it, a user ID can be issued immediately.
The JPS list of what you need (Japanese) names three items: the access key, your Basic Pension Number and an email address. According to the access key registration guide (Japanese), JPS then emails a confirmation link, which is valid for 24 hours after sending.
Access keys expire. The JPS error FAQ (Japanese) says the validity period is three months. If yours has expired, the same page explains that you can continue the application without it. The user ID is then sent by post.
Registering without an access key: allow time for the post
Without an access key, you apply online with your Basic Pension Number and an email address. The JPS step-by-step FAQ (Japanese) says the "User ID notice" usually arrives about five business days after the application, and can take longer around the New Year and Golden Week holidays.
The notice goes to your address on the JPS record. If you apply a few days before your flight, the letter may arrive after you have left. Apply early enough to receive it at your Japanese address, and log in once before you depart to confirm that it works.
If you do not know your Basic Pension Number, see our guide to confirming your Basic Pension Number.
Registration from outside Japan
You can still register. The JPS overseas FAQ (Japanese) says to apply using the "no access key" option. If your entries match the record for your Basic Pension Number, a user ID is issued and mailed to the overseas address you entered. JPS’s page on pension statements sent abroad (Japanese) describes the same arrangement and asks for overseas addresses to be written in the Latin alphabet.
International post can take longer than five business days, so do not leave registration until you urgently need the record.
If you forget your ID or get locked out
The JPS forgotten ID FAQ (Japanese) says that you must register again, because the same user ID cannot be reissued. IDs and passwords are not given out by phone. Store your user ID and password somewhere you will still be able to reach abroad, such as a password manager.
If the screen says your user ID is locked, the lockout FAQ (Japanese) asks you to call the dedicated number for pension statements and Nenkin Net. You will need your Basic Pension Number or the 12-digit inquiry number on your pension statement. The lock is released by the second business day after your request.
The dedicated phone line (Japanese) is 0570-058-555. That number cannot be used from overseas or from numbers starting with 050. Use 03-6700-1144 (Tokyo) instead; from abroad, dial Japan’s country code (+81) and drop the first 0. The line is open on weekdays and the second Saturday of each month, Japan time; check the page for current hours.
A short checklist before departure
- Find your Basic Pension Number.
- Register for a Nenkin Net user ID, with an access key if you have a valid one.
- Use an email address that will keep working after you move.
- Log in once with the user ID and password, not through Mynaportal.
- Save a dated copy of your pension record. Our record-checking guide explains what to look for.
Access to Nenkin Net does not submit a pension claim. If you are deciding whether to claim the lump-sum withdrawal, read our pension refund guide and add the steps to your departure checklist.
