Vessel Description

SHUOUMARU is a small Japanese-flagged general cargo vessel operating within Japan's extensive coastal trading network, known as the "naiko" (domestic coastal shipping) sector. Built in 2014, the vessel is representative of the modern small coastal freighter class commonly employed in Japanese inter-island and coastal supply operations. With a gross tonnage of 499 GT, the vessel falls within the sub-500 GT category, which is significant under Japanese maritime regulations governing manning and certification requirements for coastal trading vessels. The vessel supports Japan's robust domestic maritime logistics infrastructure, which relies heavily on small coastal cargo ships for the movement of goods between ports along the Japanese archipelago.
