事前通知

What the registry falls back on when a seller cannot provide their 登記識別情報 and nothing else has settled who they are: the registrar writes to the registered holder, tells them an application has been filed, and asks them to confirm within a set period that it is genuine, and may not complete the registration unless that confirmation arrives[1]. It does not run at all where a qualified agent's 本人確認情報 or a notary's authentication has already established that the applicant is the registered holder[1]. Where the application transfers ownership and the holder's registered address was itself changed recently, a second notice also goes to the previous address on the record[1], sent as mail that may not be forwarded[2]. That second notice is narrower than it sounds: it is not sent once three months have passed since the address change was filed, nor where the change was only to an administrative name or a clerical error, nor where the holder is a company, nor where a 本人確認情報 has already put the applicant's identity beyond doubt[2]. It is a deliberate speed bump aimed squarely at impersonation: forging a document presented at a counter is one problem, and intercepting post sent to the real owner's registered address is a much harder one.
