Read each seller's grading system
Japanese resale stores often publish detailed condition labels, but grading vocabulary and thresholds vary by company. Ask for the shop's own scale, item-specific photographs, repairs, odour and missing accessories. Do not assume a grade from one chain means the same thing at another.
Confirm authenticity and return terms
Buy from a reputable business with a written authenticity policy and an identifiable return route. For a valuable watch, bag or jewel, consider independent inspection. Keep the Japanese listing, receipt and any condition card; translated summaries may omit qualifications.
Plan size, service and language
Check dimensions in centimetres and verify the exact model or reference. Ask whether the brand will service a piece bought from a reseller and whether that service is available in your home market. Use written questions or a trusted translator for condition and return details.
Check customs and travel logistics
Before purchase, verify current Japanese tax-free shopping rules with official sources and check the destination customs authority for return-home requirements. Confirm whether your airline allows the purchase in cabin baggage and keep fragile goods protected during transit.
