The Yayoi period (弥生時代 Yayoi jidai) is a time in the history of Japan which is traditionally dated 300 BC to 300 AD.
Early evidence of Yayoi culture is found on the island of Kyūshū. Over time, it spread to the island of Honshū.
Iron and bronze were first used in Japan at about the same time. Iron was used for tools and weapons. Bronze was used for ritual objects such as mirrors, daggers and spears.
The Yayoi tools included as axes and hoes for agriculture etc., but also weapons such as arrowheads and swords.
