Dōhoko (ritual spear blade)

This bronze spear blade is said to have been excavated at Okamoto-chō, Kasuga City, in modern Fukuoka Prefecture. The blade has no attachment hole at the end, which suggests that it had no practical use but, like dōtaku and mirrors at the time, was made for burial in a ceremony possibly connected with agriculture. Its form is copied from a Chinese original.

Iron and bronze were introduced into Japan at about the same time, so there was no recognizable 'Bronze Age' predating the use of iron. Iron was quickly recognized as the stronger of the two metals, more suitable for producing tools and weapons. Bronze was used for ritual objects such as mirrors, daggers and spears such as this one.
