MIRAI — Other · IMO 6919423

MIRAI has not broadcast an AIS position for 234 days. The most recent broadcast placed it in the East China Sea, on 19 Mar 2026, 02:49 UTC. It was sailing from TOBATA to KANDA ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

MIRAI broadcasts MMSI 431939000 and is registered as IMO 6919423, with call sign JNSR . 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.

MIRAI is a maritime vessel registered under the JP flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full JP flag list at /flag/jp.

MarineRadar shows the latest AIS broadcast from MIRAI above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

MIRAI is classed by NIPPON KAIJI KYOKAI (NKK), the classification society responsible for inspecting the vessel against safety, structural and operational rules. The vessel's design class is inferred from its dimensions, gross tonnage and dead weight, all of which are listed in the Identity and Specifications panels on the vessel page. MIRAI has a gross tonnage of 8,706 GT.
