A very early pottery tradition
Jomon is the name given to a long prehistoric period in Japan, usually dated from more than ten thousand years ago until roughly the last few centuries before the common era. The word means “cord-marked” and refers to the patterns pressed into the clay surfaces of its pottery. Jomon vessels are among the oldest known ceramics in the world, and exact dates for the beginning are revised as new radiocarbon results appear, so it is safest to speak in broad terms.
The name is a Japanese rendering of “cord-marked,” a description first used in the late nineteenth century for decorated shards from a shell mound near Tokyo. It later became the standard label for the culture and the period.
How the cord marks were made
The typical Jomon surface carries impressions made by pressing or rolling twisted cord against wet clay. Rope-like cords were sometimes wrapped around sticks and rolled across the surface, leaving repeated patterns. Other techniques included incising lines with sticks or shell edges, pinching, adding strips of clay, and making small punched dots. Potters shaped vessels by building them up from coils or lumps of clay rather than throwing them on a wheel, and the wheel was not part of this tradition.
These pots were fired in open fires or shallow pits, not in the kilns described elsewhere in the discussion of how pottery is fired. Open firing typically reaches lower temperatures, so Jomon pottery is earthenware: porous, fairly soft and usually brown, gray or reddish.
Shapes and change over time
Archaeologists divide the Jomon period into several phases (often called Incipient, Initial, Early, Middle, Late and Final), though the labels and dates differ somewhat between sources. Across them, pottery changes in noticeable ways.
- Early vessels were often small, with rounded or pointed bases, and fairly plain.
- Deep, bucket-like pots with flat bottoms became common, well suited to cooking over a fire.
- Elaborate Middle Jomon vessels have dramatic rims with sculptural projections, often called “flame-style” in modern descriptions. They are especially associated with the Niigata region, though similar tendencies appear elsewhere.
- Later vessels sometimes became finer and more varied in form, including spouted vessels and shallow bowls.
Regional styles varied, which helps archaeologists identify where a fragment came from and roughly when it was made.
What the pots suggest about daily life
Jomon people are generally understood to have been hunter-gatherers and fishers who also gathered nuts and other plant foods, and many lived in settlements that were relatively settled for extended periods. Ceramic cooking pots fit that way of life. Pottery makes it possible to boil food, soften tough plant material and prepare nuts such as acorns, which often need processing to become palatable. Soot and food residues on the interiors of some vessels support the view that many were used for cooking, although the details of which foods were prepared vary by site.
At the same time, the most striking pieces were probably not everyday pots. Highly decorated vessels may have served for ceremonies or special gatherings, but this is an interpretation; the evidence is incomplete, and scholars hold different views. Jomon sites also yield clay figurines called dogu, whose purpose is debated, along with ornaments and other objects.
Jomon and later Japanese ceramics
After the Jomon period came the Yayoi period, associated with rice farming and with new influences from the Asian mainland. Yayoi pottery is typically smoother, more thinly walled and less decorated than Jomon ware, a change often linked to different uses and techniques. Later developments, such as the arrival of the tunnel kiln and hard gray Sue ware in the Kofun period, moved ceramics toward high-fired stoneware. These shifts are part of the larger story laid out in the cultural timeline of Japan.
It would be too simple to describe Jomon pottery as the direct ancestor of every later tradition. Many techniques changed or were introduced, and later potters drew on mainland knowledge. Still, some modern artists and designers have found inspiration in Jomon forms, valuing their energy and directness.
Seeing Jomon pottery today
Jomon vessels are held in museums in Japan and abroad, and some regions have local archaeological sites with displays and reconstructed dwellings. Viewing them in person gives a sense of their scale and the hand of the maker. The patterns are not simply decoration; they are evidence of choices that people made long before written records, and archaeologists continue to refine the picture.
