Title

The 17th Century Wooden Shipwreck off Hatsushima Island, Japan

Description

The Asian Research Institute of Underwater Archaeology (ARIUA) at Fukuoka and Tokyo University of Marine Science and Technology, which is a member institution of the UNESCO Underwater Archaeology Unitwin Network, have researched upon the 17th century wooden shipwreck off Hatsushima Island in front of Atami city, Shizuoka Prefecture, since 2011. The shipwreck lies on the seabed at the depth of 20 metres, 200 metres from the western shore. It consists mainly of a cargo of roof tiles or grinding bowls and some parts of the wooden hull. Judging from them, the original vessel seems to have been a 17th or 18th century wooden freighter or kaisen ( 廻船 ), which left a port of western part of Japan for the capital town of Edo; most of well made roof tiles were not made in eastern part at that time. Because most of the roof tiles are high-quality and one of them is marked by the wild ginger trefoil coat of arms of the Shogunate family, they might mean to have been used for the Edo Shogunate castle. In 2011 and 2012, archaeologists with financial assistance from the Nippon Foundation, did the submersible survey upon this wreck site, about which local fishermen had already known to identify its exact position. In 2013, then, its bathymetry was made with a multibeam sonar. In order to make a precisely measured drawing of the 5 metre square wreck site, an AUV in 2013 and a ROV in 2015, both of which were developed uniquely by Tokyo University of Marine Science and Technology, and divers in 2016 were deployed to collect numerous underwater photos to generate 3D photogrammetric models with photogrammetry software Agisoft ‘PhotoScan’.
