SEVEN ISLAND TOMO — Wing In Grnd · IMO 8819160

SEVEN ISLAND TOMO has not broadcast an AIS position for 8 days. The most recent broadcast placed it in the Sea of Japan, on 29 Oct 2026, 00:22 UTC. It was sailing from TOKYO to KISARAZU. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SEVEN ISLAND TOMO broadcasts MMSI 431009153 and is registered as IMO 8819160, with call sign JM5778. 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.

SEVEN ISLAND TOMO is classified as a wing in grnd vessel registered under the JP flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full wing in grnd fleet at /vessel-type/high-speed-craft and full JP flag list at /flag/jp.
