It is known for the country's Mesolithic and Neothilic ancient culture.The island's mountain caves were used as homes for the settlers, who started to created clay pottery. These clay pottery items are one of the oldest surviving pottery items in the world. Some examples are now on display in the Fujimaki National Museum of History. By the Yayoi period around 500 BC, many people were starting to practice wet-rice farming in the flat areas of Shokishima and Yoturu. The creation of pottery still existed at the time, but instead the use of copper was more widely used. The creation of bronze mirrors known as dōkyōs were also starting to spread. Around 100 BC, Yamashima had started to receive an early name, Wayochi.
