The Digital Agency announced on October 13, 2026, that it has updated the list of financial institutions excluded from some procedures related to the system that links bank and savings accounts to an individual's My Number ^[1]. According to the notice, customers of the listed institutions should be aware that certain services are not available through those banks ^[1].

Specifically, the excluded institutions are not covered when a person tries to register their My Number with a bank by going through another financial institution or through the Mynaportal online portal ^[1]. The exclusion also applies to the provision of information about deposit and savings accounts in the event of inheritance or a disaster, meaning these institutions will not share such account information through the linked system in those circumstances ^[1]. In addition, the excluded banks are not included in the process of accepting inquiries for the provision of account information during inheritance or disaster situations ^[1].

The Digital Agency published the full, updated list of affected financial institutions as a downloadable Excel file on its website, described as a 15-kilobyte document ^[1]. The agency did not specify in this notice which particular banks are newly added to or removed from the list, nor did it explain why any institution is excluded, so readers who want those details should consult the linked Excel file directly ^[1].

For foreign residents in Japan who use the My Number bank account linking system, this update is a reminder to check whether their own bank appears on the exclusion list before relying on cross-institution My Number registration or on inheritance- and disaster-related account information services ^[1]. If a person's bank is on the list, they should not assume these particular conveniences are available and should instead confirm directly with their bank what alternative steps, if any, are required ^[1]. The notice does not provide information on fees, application procedures, or who is eligible for the broader bank account linking system itself, nor does it give a history of previous versions of the exclusion list ^[1]. Anyone affected should refer to the official Digital Agency page and the attached Excel document for the current, authoritative list of excluded institutions ^[1].
