At a glance
Share of Japan Post consignments delivered on the very first attempt over the trailing 30 days, before any recipient-absent redelivery. A high rate means parcels are reaching addressees first time; a low rate means the network is burning attempts on redeliveries, which adds transit days and cost. The card alerts below 85 percent.
What it tracks
The card computesfirst_attempt_delivered ÷ total_delivered over the rolling 30 days, reading each consignment’s tracking-event stream and scoring 1 only when the first delivery attempt produced a delivered scan with no intervening recipient-absent (ご不在) event. On Japan Post’s domestic Yu-Pack network the first-attempt picture is shaped by Japan’s household pattern: many urban recipients are out during the day, so a first attempt often fails and the parcel routes into Japan Post’s redelivery machinery (the Yubin app, a timed redelivery window, or Konbini convenience-store and locker pickup). That redelivery still reaches the customer, but it does not count here: this card only rewards the first knock. A reading comfortably above 85 percent usually means recipients are choosing locker or convenience-store collection at checkout, or that the merchant ships to a metro mix with high daytime occupancy. A dip below 85 percent points at an address-quality problem, a service mix skewed to attended home delivery, or a seasonal absence spike (Obon in August, the Oshogatsu New Year window). Read it next to On-Time Delivery Rate, since each failed first attempt adds a redelivery cycle that pushes transit days out, and next to Exception Rate, where the recipient-absent events surface. The 30-day window smooths the day-of-week swing in household occupancy.
