Nagasaki Prefecture is located in the northwestern part of Kyushu, and islands such as the Goto Islands, Hirado Island, Iki Island, and Tsushima Island are scattered in the flow of the Tsushima Warm Current. 132 km from the mainland of Kyushu across the Genkai Sea and the Tsushima Strait East Channel. The distance to the Korean Peninsula is about 49.5 km across the Tsushima Strait West Channel. 　So far, surveys in Nagasaki Prefecture have been conducted at about three sites located in the intertidal zone of the coast. The excavation survey is conducted when the tide is low, and the survey ends when the tide comes in, which is inevitably inefficient. In addition, at the 'Takashima Undersea Ruins' in Takashima, Matsuura City, a survey was conducted to confirm the traces of the Genko, and many other relics were confirmed. In connection 　With this report, a certain amount of pressed-patterned pottery and stone tools from the early Jomon period was excavated from the seabed at a depth of about 25m during a survey to confirm Genko, and the inclusion layer was confirmed by diving and collected. The vegetation of that time was also reconstructed from the soil of the inclusion layer. The ``Nishikaratsu Undersea Ruins'' in Karatsu City, Saga Prefecture is also an archaeological site located in such an intertidal zone. 　Under these circumstances, Mr. Kazutomo Mizunoe stated that he could not confirm anything that indicated a direct relationship between Jomon pottery between Japan and Korea. This unexpected statement made me feel the need to consider the embossed pattern pottery of the early Jomon period at the Takashima Undersea Ruins located under the seabed. The fact that the embossed patterned pottery culture of the early Jomon period was confirmed 25m below the seafloor in northwestern Kyushu naturally suggests that the same could be said of South Korea on the opposite shore. It seems that there are many difficult aspects to the comparison of the existence of ruins under the sea floor, but it seems necessary to take it into consideration. Of course, I knew about changes in the sea level in the Japan-Korea Strait from textbooks, but I felt it more familiar. It was also confirmed that the Tsugume no Hana Ruins, which faces the Hirado Strait, was formed during the Jomon period when the sea level was higher than it is today.
