KYOKUSHO MARU — Tanker · IMO 9240902

KYOKUSHO MARU has not broadcast an AIS position for 11 days. The most recent broadcast placed it in the Sea of Japan, on 28 Oct 2026, 03:19 UTC. It was sailing from NIIHAMA ANCH to SAIJO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

KYOKUSHO MARU broadcasts MMSI 431501667 and is registered as IMO 9240902, with call sign JL6605. 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.

KYOKUSHO MARU 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.
