# Avg Transit (days), Japan Post

> Avg Transit (days) for Japan Post stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

**Card class:** [Non-Hero](/nerve-centre/overview#card-classes-explained)  •  **Category:** [Delivery Performance](/nerve-centre/connectors#connectors-by-type)

## At a glance

> Mean elapsed time from first carrier scan to delivered scan for Japan Post shipments over the trailing 30 days, compared against the prior period. It is the door-to-door speed customers feel, blended across domestic Yu-Pack and international EMS. The alert fires above 5 days, which for a mostly-domestic Japan Post operation signals that something has slowed the network or that the international share has grown.

## What it tracks

The card measures `delivered_scan_timestamp - first_scan_timestamp` per shipment, averaged over the rolling 30-day window with a period-over-period comparison, and counts only consignments with both a first scan and a delivered scan (in-flight parcels are excluded until they land). Domestic Yu-Pack within Honshu typically clears in 1 to 2 days; Hokkaido, Okinawa, and remote-island (離島) lanes run longer; EMS to the US, EU, Australia, or elsewhere in Asia adds international line-haul and customs dwell, so it can run 3 to 7 days depending on corridor. Because the figure is blended, a rising international (EMS) share lifts the average even when each lane is performing normally, so read it alongside the service mix. The `>5 days` alert is the prompt to separate a genuine slowdown from a mix shift. When it trips, check [Late Shipments](/nerve-centre/kpi-cards/japan-post/late-shipments) for the contractual miss count, [OTD by Route](/nerve-centre/kpi-cards/japan-post/otd-by-route) for lane concentration, and [Shipments with Tracking-Event Gap (24h domestic / 5d EMS)](/nerve-centre/kpi-cards/japan-post/shipments-with-tracking-event-gap-24h-domestic-5d-ems) in case missing scans are inflating the measured duration. Scan timestamps are carrier-local (JST at origin), and tracking-event ingestion can lag, so very recent deliveries settle into the average over the following hours.

## Reconciling against the source

Reconcile against the per-consignment scan history in the [Japan Post tracking service](https://trackings.post.japanpost.jp/services/srv/search/) (追跡サービス) and the Shipping Management (発送管理) view in the business portal; compute first-scan to delivered-scan per parcel in JST. Differences are usually tracking-event latency or the exclusion of still-in-transit parcels.
