Tracking updates depend on the destination country's postal service scanning the item. | Wait up to 5 business days for the first scan in the destination country. Check directly with the destination country's postal carrier if available. | If no update 15 business days after dispatch from Japan, contact Japan Post to initiate an inquiry. | | Tracking number changes at border | Some destination country carriers assign a new tracking number when they receive the package from Japan Post, causing the Japan Post number to appear stale. | Contact the destination country's post office with the original Japan Post tracking number to obtain the local tracking reference. | Japan Post can investigate if requested via their inquiry form. | | Package stuck 'in customs' | The package requires additional documentation, duties payment, or inspection by destination country customs. | Watch for a customs notification from the destination postal service. Provide documentation or pay duties as requested. | If held more than 10 business days with no customs notification, contact both Japan Post and the destination country's customs authority. | | Website slow during peak seasons | High query volumes during holiday seasons and major sales events (e.g., Black Friday) can slow the Japan Post tracking portal. | Try tracking at off-peak hours. Use a third-party tracking aggregator as an alternative. | No escalation needed; this is a temporary system load issue. | ## Japan Post Tracking FAQs ### How do I track a Japan Post EMS shipment?
