Abstract: Shinan shipwreck was discovered at a 20-m sea bottom of southeast offshore of Korea in 1976, carrying over 20,000 items such as china, metal goods, stone and wooden materials, and 28 tons of copper coins. There is evidence that the ship had a wooden plate displaying 3 June 1323, indicating that the ship was a trading ship and sailed from China to Japan (e.g., Hakata in Fukuoka Prefecture and Tofuku-ji Temple in Kyoto Prefecture) in the early 14thC. In the past study, it was speculated that Chinese cedar (Cunninghamia spp., Taxodiaceae) was used to make wooden boxes in the ship; however, no dendchronological analysis was performed to substantiate the origin of the cedar. The objective of this study was to performdendrochronological analysis on the wooden boxes to date and identify its origin. Microscopic wood anatomical re-examination of the boxes in this study revealed that the cedar was in closer proximity to Japanese origin. Further dendrochronological analysis was also conducted on the wood samples from the ship using tree ring patterns of Japanese cedar (Cryptomeria japonicaD.Don, Taxodiaceae) growing in western Japan. As a result, this study found a high agreement between the two chronologies, demonstrating that Japanese cedar was used to make the wooden boxes. Finally, the analysis also dated the outermost ring of sapwood remains of the discovered wooden boxes to be 1316 AD.

The study results demonstrated that dendrochronological analysis can contribute to identifying not only place of origin (i.e., country of origin) of timber or wood products in the past but alsotheir distribution channels.
