The Japanese archipelago experienced the introduction of bronze during the beginning of the Early Yayoi period (≈300 BC), which saw the introduction of metalworking and agricultural practices brought in by settlers arriving from the continent. Bronze and iron smelting techniques spread to the Japanese archipelago through contact with other ancient East Asian civilizations, particularly immigration and trade from the Korean peninsula and ancient Mainland China. Iron was mainly used for agricultural and other tools, whereas ritual and ceremonial artifacts were mainly made of bronze.
