Jōmon Culture: Japan's Ancient Hunter-Gatherers and First Pottery

The Jōmon culture was the prehistoric culture of the Japanese archipelago from about 14,000 to 300 BC, best known for its cord-marked pottery, some of the oldest in the world. Over more than ten thousand years, Jōmon hunters, fishers and gatherers built long-lasting villages, shell mounds and stone circles, and made striking clay figurines called dogū. The culture matters because it shows that pottery, permanent settlement and complex ritual life could develop without full-scale farming.

Background: Japan at the end of the Ice Age

During the last Ice Age, lower sea levels joined parts of the Japanese islands to each other and, in the north, brought them close to the Asian mainland. People had already lived in Japan for tens of thousands of years, making stone tools in what archaeologists call the Palaeolithic period.

As the climate warmed after about 15,000 years ago, sea levels rose and Japan became the island chain it is today. Broadleaf forests of oak, chestnut and walnut spread across much of the land. Rivers, bays and long coastlines offered fish and shellfish, while the forests held deer, wild boar and abundant nuts.

The Jōmon culture grew out of this rich and varied environment. Its people adapted to it so successfully that their way of life lasted, with many regional changes, for longer than the whole of recorded history in most of the world.

The first pottery

The defining feature of the Jōmon is its pottery. Sherds from the Odai Yamamoto I site in Aomori Prefecture, in northern Honshu, have been dated by radiocarbon to roughly 16,000 years ago or a little earlier, although the exact calibration is debated. This places Jōmon pottery among the earliest anywhere, alongside early wares from southern China and the Russian Far East.

The earliest vessels were simple, deep pots with pointed or rounded bases, probably used for boiling food. Cooking in pots made acorns, shellfish and other foods easier to eat and to store. Later Jōmon potters developed a huge range of shapes and decoration.

The name Jōmon means cord-marked. Potters pressed or rolled twisted plant cords into wet clay to create textured patterns. The term goes back to the American zoologist Edward S. Morse, who excavated the Ōmori shell mound near Tokyo in 1877 and described the finds as cord marked pottery, a phrase later translated into Japanese.

In the Middle Jōmon period, potters in central Japan produced spectacular flame-style vessels, known in Japanese as kaen doki, with rims that rise in swirling, flame-like projections. Some of the finest come from sites in Niigata Prefecture, such as Sasayama in Tōkamachi, where a group of these pots has been designated a National Treasure.

Periods of the Jōmon

Archaeologists divide the Jōmon into six periods. The dates below are those commonly cited; they vary between regions and continue to be refined by radiocarbon dating.

The traditional end date of 300 BC is now under revision. Radiocarbon dates suggest that the wet-rice farming of the following Yayoi culture began in northern Kyushu several centuries earlier, perhaps around 1000–800 BC.

Daily life and settlements

The Jōmon were hunter-gatherers, but unlike many such peoples they often lived in permanent or semi-permanent villages. Their houses were pit dwellings: a round or oval floor dug into the ground, with a roof of poles covered in thatch, bark or earth. Villages often clustered around an open central space, sometimes with burial areas.

Food came from many sources. People gathered chestnuts, walnuts, acorns and horse chestnuts, some of which needed soaking or boiling to remove bitter tannins. They hunted deer and wild boar with bows and arrows and used dogs as hunting companions. Along the coasts they fished, harpooned sea mammals and collected shellfish.

The remains of shellfish meals built up into shell mounds, called kaizuka. Several thousand are known across Japan. Because the shells reduce soil acidity, these mounds preserve bones, tools and burials that would otherwise have decayed.

Jōmon people also managed plants. At Sannai-Maruyama, the abundance of chestnut suggests that people encouraged and tended chestnut groves. Studies of seed impressions in pottery show that soybeans and azuki beans became larger over time, a sign of gradual domestication. Small-scale cultivation of plants such as barnyard millet has also been proposed. Even so, the Jōmon never relied on cereal farming.

Sannai-Maruyama and other key sites

The best-known Jōmon settlement is Sannai-Maruyama in Aomori City, occupied from about 3900 to 2200 BC. Excavations from 1992 revealed hundreds of pit houses, large long houses, storage pits, burials and huge quantities of pottery, stone tools and figurines. The remains of a structure with six massive chestnut posts, each about 1 metre in diameter, have become a symbol of the site.

How many people lived there at one time is debated. Estimates range from a few dozen to several hundred, depending on how many houses were in use at once. Either way, the site shows long-term planning, trade and ritual on a substantial scale.

Other important sites include the Ōyu stone circles in Akita Prefecture, two large circles of arranged stones from the Late Jōmon, and the Kamegaoka site in Aomori, known for its Final Jōmon pottery, lacquerware and figurines. In 2021 seventeen sites in Hokkaido and northern Honshu, including Sannai-Maruyama and Ōyu, were inscribed on the UNESCO World Heritage List as the Jomon Prehistoric Sites in Northern Japan.

Dogū, ritual and craft

The most famous Jōmon objects are dogū, small clay figurines. Many show human figures, often with female features, while others have masked faces or bulging, goggle-like eyes. The goggle-eyed type, called shakōki-dogū, is typical of the Final Jōmon in northern Japan, with fine examples from Kamegaoka.

Nobody knows exactly what dogū were for. Researchers have suggested that they were used in fertility, healing or protective rituals. Many were found broken, and some scholars think they were broken deliberately, perhaps to transfer illness or misfortune, though this cannot be proven.

Other ritual objects include stone rods, clay masks and earrings. Jōmon craftspeople also made lacquered wood and pottery using sap from the lacquer tree, decorated in red and black, which shows a sophisticated knowledge of materials. Jade from the Itoigawa area in central Japan was traded widely as beads and pendants.

Population, climate and change

The Jōmon population was never large. A widely cited estimate by the archaeologist Koyama Shūzō, based on site counts, suggests a peak of around 260,000 people across Japan in the Middle Jōmon, mostly in eastern Japan. Numbers then fell in the Late and Final periods, possibly because of cooler climate and reduced food supplies, although all such figures are rough.

From around 1000–800 BC, migrants and ideas from the Korean peninsula brought wet-rice farming, bronze and iron to northern Kyushu. This new way of life, called Yayoi, spread east over the following centuries. Jōmon people did not simply disappear: many adopted farming, mixed with newcomers and passed on parts of their culture. In Hokkaido, hunter-gatherer traditions continued in the Epi-Jōmon culture.

Myths and facts

Myth: Jōmon pottery is definitely the oldest in the world. Jōmon pottery is among the earliest, but older pottery fragments are known from southern China, including Xianrendong Cave, where sherds have been dated to about 20,000 years ago.

Myth: dogū show ancient astronauts. Popular books have claimed that goggle-eyed dogū depict space suits. Archaeologists see them as stylised human figures, and the goggle-like eyes may imitate snow goggles or simply be an artistic style.

Fact: the Jōmon were not simple nomads. Many Jōmon communities lived in the same place for generations, stored food, traded over long distances and built monuments.

Why it matters

The Jōmon form part of a wider story of early pottery and settled life in East Asia. Comparable developments took place in Korea during the Jeulmun pottery period and in China, where the Shangshan culture combined early pottery with the first use of rice.

Unlike the farming societies of the Neolithic Revolution in the Near East, the Jōmon reached a high degree of settlement and craft without depending on crops. This makes them a key case for archaeologists studying how complex societies can arise among hunter-gatherers.

In short, the Jōmon culture shows that pottery, villages and rich ritual life did not require farming. Its people thrived in Japan for more than ten thousand years, and their art, especially flame-style vessels and dogū, remains one of the most distinctive achievements of the prehistoric world. Their genetic and cultural legacy is still part of the population of modern Japan.
