Vessel Description

The Kousyu Maru is a small Japanese-flagged coastal cargo vessel operating under the Japanese domestic shipping registry. With a gross tonnage of 499 GT — a common threshold in Japanese coastal shipping that allows operation under a simplified regulatory framework — the vessel is typical of the coaster class widely employed in Japan's extensive inter-island and coastal freight network.

Built in 2014, the vessel is engaged in the transport of general or bulk cargo along Japanese coastal routes, serving the country's reliance on sea transport for domestic goods movement. As a sub-500 GT vessel, she is regulated under Japan's Coastal Shipping Act and operates primarily within Japanese territorial and internal waters.

The vessel is identifiable on AIS networks under MMSI 431005339 and maintains radio communications under call sign JD3682, consistent with Japanese Maritime Administration allocations.


Data Notice: This profile is compiled from publicly available maritime databases (IMO GISIS, MarineTraffic, VesselFinder). Some fields may be incomplete due to limited public disclosure for smaller coastal vessels. Users are advised to verify operational details with the vessel's registered owner or Japanese Coast Guard records.
