🇯🇵 Japan
Pacific Ocean · General Cargo Port
In the last 180 days, ArcNautical recorded 27 vessel arrivals at Hiroshima, with Cargo accounting for 59% of port calls — higher than the Pacific Ocean regional average of 52%. Voyages from Hiroshima 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.
Across 27 distinct vessel arrivals, 27 carry a confirmed AIS ship-type code. The most common categories at Hiroshima:
Hiroshima 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 5,331 distinct vessel detentions (sourced from OpenSanctions, as of 2026-06-14). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
