The Jōmon Pottery (縄文式土器 Jōmon-shiki Doki) is a type of ancient pottery which was made during the Jōmon period in Japan. The term "Jōmon" (縄文) means "rope-patterned" in Japanese, describing the patterns that are pressed into the clay.
The pottery vessels crafted in Ancient Japan during the Jōmon period are generally accepted to be the oldest pottery in Japan.
Bits of pottery discovered in a cave in the northwest coast of modern-day Kyushu date back to as far as 12,700 BCE in radiometric dating tests. It is believed by many that Jōmon pottery was probably made even earlier than this date. However, due to ambiguity and multiple sources claiming different dates based on different dating techniques, it is difficult to say for sure how far back Jōmon Pottery was made. Some sources claim archaeological discoveries as far back as the 14th millennium BCE.
The Jōmon Period in Ancient Japan lasted until roughly 300 BCE. From there, it is divided into six periods: Incipient Jōmon, from 10,500-8,000 BCE, Earliest Jōmon, from 8,000-5,000 BCE, Early Jōmon, from 5,000-2,500 BCE, Middle Jōmon, from 2,500- 1,500 BCE, Late Jōmon, from 1,500-1,000 BCE, and Final Jōmon, from 1,000-300 BCE. There are over 80 sites in Japan where Incipient Jōmon pottery vessels have been found, but the majority of Jōmon pottery remains come from the later periods.
