• Request Change of Residency Status: Inform the bank representative about the error code ‘512U’ and your intention to change from “Non-resident” to “Resident.” 
• Verification and Update: The bank will verify your documents and update your residency status accordingly. 

Over Six Months in Japan (Non-Working Individuals) 

If you have been in Japan for over six months but do not have employment, you can still change your status to “Resident” by following these steps: 

• Gather Required Documents: Ensure you have the following documents ready: 
• 1. Bankbook (issued by the bank where you hold your account) 
  2. Residence card (Zairyu Card) 
• Visit the Nearest Bank: Go to the nearest bank that supports residency status changes.

• Request Change of Residency Status: Inform the bank representative about your intention to change from “Non-resident” to “Resident” due to being in Japan for over six months. 
• Verification and Update: The bank will verify your documents and update your residency status accordingly.
