In the Yayoi period (ca. 5th century BC–3rd century AD), polished stone and metal tools were introduced from China and the Korean Peninsula along with wet rice cultivation. Stone tools included rice reapers for harvesting, a range of polished axes and adzes for making wooden agricultural tools, and polished arrowheads that could have been used as weapons. These tools were subsequently made with iron.
