When people in their 50s order from Rakuten, Amazon Japan, etc., they have to track four stages—domestic shipping in Japan (Yamato, Sagawa), international shipping (EMS, DHL), domestic customs clearance (Korea Customs Service), and domestic delivery (Korea Post, CJ)—on different websites. Because the tracking number formats differ, if they miss the transition point, they may leave the customs hold status unnoticed for 1-2 weeks, and tracking becomes even more complicated when using a forwarding service.
Entering just one order number or tracking number for a Japan direct purchase displays all four stages—domestic shipping in Japan → international shipping → customs clearance → domestic delivery—as a single integrated timeline. Sends immediate KakaoTalk/SMS alerts when customs hold or tax payment is required. Supports forwarding service integration.
