Yes, the Japan Railways (JR) Group requires that your 10-year consecutive residency be proven by a single official document (or one set issued as a single certificate).

To avoid being denied your JR Pass, please understand the "Single Jurisdiction Rule":

• The Principle of Continuity: You cannot combine multiple independent certificates from different consulates to reach the 10-year total. For example, presenting one certificate for 4 years in Vancouver and another for 6 years in Toronto is not accepted by JR.
• Moving Between Jurisdictions: If you have moved between different consular jurisdictions (e.g., from BC to Ontario), your current consulate must be able to include your previous residence history on your new certificate, proving a "continuous" 10-year period under their seal.
• Document Date: The registration date or "Date of Arrival" printed on that single document must be in the same month as your purchase, but 10 years prior (or earlier).

Important: If your official residency document does not explicitly cover the full 10-year period on its own, you will not meet the eligibility requirements for the Japan Rail Pass. Please consult your local Japanese Consulate to ensure they can issue a document that reflects your entire 10-year history before ordering your voucher.
