Why Japan's Port Bottleneck Moved From the Berth to the Gate

Vessel wait times at Tokyo and Yokohama have normalized to roughly a day, leading many international shippers to assume Japan's port bottlenecks have resolved. Cargo movement on the ground tells a different story. The constraint hasn't disappeared — it has shifted from berth capacity to the sea-land interface: terminal gates, truck availability, and warehouse receiving.

This is the entrenched reality of Japan's "2024 Problem," the industry's shorthand for the Work Style Reform Act's cap on commercial truck driver overtime. Combined with an aging driver workforce, the cap has tightened drayage capacity nationwide. NX Research Institute estimates a transport-capacity shortfall of roughly 14.2% in FY2024, rising toward 34.1% by FY2030 without further countermeasures — though industry and government efforts have already offset part of the near-term gap. The Kanto corridor, which feeds Japan's largest metropolitan consumption network, is feeling this most acutely, with terminals reporting truck queues that stretch several hours during peak windows.

The result is a paradox importers don't see on a vessel tracker: containers discharge quickly, then sit. Yard dwell and gate turnaround times at Tokyo and Yokohama have lengthened, and reefer plug utilization at Yokohama runs high enough that even short delays raise real questions for temperature-sensitive cargo. Much of this is a timing problem as much as a capacity one — Japanese delivery customs concentrate truck arrivals into the same afternoon windows, which is why Tokyo Port has pushed CONPAS, a gate reservation system, and off-peak pickup incentives to spread the load.

For importers, this changes what "on time" means. Vessel ETA and customs clearance no longer guarantee physical availability at the warehouse — a distinction that matters most for wine, cold-chain goods, and seasonal inventory tied to windows like Golden Week or year-end gifting season. A cleared, discharged container can still be a container going nowhere until a truck slot opens up.

ARC2N coordinates freight, customs clearance, and inland drayage across Japan through an established network of licensed local operators. Because we handle end-to-end import operations — both for overseas brands entering Japan and for our own wine portfolio from Australia, Spain, and Chile — we treat the truck appointment as part of import planning, not a task that starts after the vessel arrives. We reserve drayage slots weeks ahead of ETA, align customs release timing with carrier and terminal availability, and route cold-chain shipments to avoid unnecessary plug changes and yard exposure. Acting as a single point of contact across customs, terminal, and drayage keeps cargo moving out of the gate instead of waiting on it.

Is your Japan supply chain still planning around berth schedules, or are you accounting for what happens after the container hits the ground?
