Question 1

Where is SUOU right now?

Accepted Answer

SUOU has not broadcast an AIS position for 4 days. The most recent broadcast placed it in the Sea of Japan, on 4 Sep 2026, 22:44 UTC. It was sailing from AKITA to OMINATO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for SUOU?

Accepted Answer

SUOU broadcasts MMSI 431999676. 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.

Question 3

What type of ship is SUOU?

Accepted Answer

SUOU 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.

Question 4

How can I see the live position of SUOU?

Accepted Answer

Question 5

How often is SUOU's position updated?

Accepted Answer

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.

Question 6

What class is SUOU?

Accepted Answer

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.
