HOKUYUMARU — Tanker · IMO 9256195

HOKUYUMARU has not broadcast an AIS position for 200 days. The most recent broadcast placed it in the South China Sea, on 23 Apr 2026, 09:09 UTC. It was sailing from NAGOYA to TOKUYAMAKUDAMATSU. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HOKUYUMARU broadcasts MMSI 431800616 and is registered as IMO 9256195, with call sign JG5646. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

HOKUYUMARU is classified as a tanker vessel registered under the JP flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tanker fleet at /vessel-type/tanker and full JP flag list at /flag/jp.
