Empowering Your Future: Key Capabilities of DCなび

Regaining Control: Navigating DCなび Access Challenges

⚠️ Forgot Internet Password (JIS&T) or PIN (NRK)

Cause: User has forgotten their password or PIN for their JIS&T or NRK plan.

Solution: For JIS&T, click the 'パスワードをお忘れの方はこちら' (Forgot Password?) link on the login page. You can re-issue it via the JIS&T Internet Service or by contacting the JIS&T Call Center. If you have a registered email with JIS&T, you might be able to reset it online immediately.. For NRK, use the 'ユーザーID・暗証番号 再通知・再設定' (User ID/PIN Re-notification/Re-setting) option. If you have registered your email, you can reset it instantly; otherwise, a new ID will be mailed.

⚠️ Account Locked Due to Incorrect Password Attempts

Cause: Entering the Internet Password or PIN incorrectly too many times will invalidate your account access.

Solution: You must follow the password re-issuance or re-setting procedure as described above for forgotten passwords.

⚠️ Cannot Log In with Previous J-PEC ID/Password

Cause: The login method has changed from older J-PEC IDs to institution-specific credentials.

Solution: You now need to use your Participant Account Number (加入者口座番号) or User ID (ユーザーID) and Internet Password (インターネットパスワード) or PIN (暗証番号), which are provided by JIS&T or NRK.

⚠️ Email Login Fails After Changing ID/PIN Password

Cause: Changing your ID login password (for NRK or JIS&T) can disconnect your email login linkage.

Solution: Log in using your ID (Participant Account Number/User ID) and the newly changed password. Then, navigate to the 'アカウント設定' (Account Settings) menu and update your password there to re-establish email login functionality.

⚠️ Session Invalid / Automatically Logged Out

Cause: The system automatically logs you out after a period of inactivity or if the same User ID is used to log in from another location simultaneously.

Solution: This is a security feature. Simply log in to the portal again to resume your session.

⚠️ Unsure Which Record-Keeping Company (NRK/JIS&T) Your Plan Uses

Cause: Participants may not recall which record-keeping company manages their specific pension plan.

Solution: Check the documents sent to you by your record-keeping company. If you are still unsure, contact the HR or administration department at your workplace for clarification.

⚠️ Registered Email Address Unknown or Email Not Received for Registration/Reset

Cause: You may not remember which email is registered, or verification emails are not reaching your inbox.

Solution: To confirm your registered email, log in with your ID and check the 'アカウント設定' (Account Settings) menu under email management. If registering a new email, ensure your email settings allow receiving emails from the j-pec.co.jp domain. If a temporary registration expires (e.g., after 24 hours), you may need to re-register.
