🇯🇵 Japan
Pacific Ocean · General Cargo Port
Voyages from Nagasaki in Japan cross the world's largest ocean basin, where route optimisation and weather routing have significant financial implications — a single transpacific crossing can consume hundreds of tonnes of fuel, and a one-knot speed variation over a 12-day voyage materially affects both cost and schedule. The western Pacific generates more tropical cyclones than any other basin (≈26 named storms annually), with typhoon season June–November producing winds above 150 knots and waves exceeding 15 metres. North Korea sanctions enforcement is a significant compliance concern: UN Security Council resolutions prohibit ship-to-ship transfers to DPRK vessels, and dark-activity (AIS disablement) is a common evasion signal in the East China Sea and Yellow Sea.
Routed sea distances from Nagasaki to the principal global hubs, computed by ArcNautical's routing engine — around land and through the canals a ship actually uses, not great-circle.
Limited port-call data — fewer than 10 distinct vessels observed at Nagasaki in the last 180 days. ArcNautical does not publish a vessel-type breakdown for low-traffic ports to avoid statistically misleading percentages.
Nagasaki falls under the Tokyo MoU. The Tokyo Memorandum of Understanding (Asia-Pacific) maintains the most active publicly-available regional PSC programme. Across the last 24 months, the Tokyo MoU detention dataset records 5,509 distinct vessel detentions (sourced from OpenSanctions, as of 2026-09-06). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
