Yayoi Japanball

Yayoi Japanball is an Iron Age era in the history of Japanball traditionally dated 300 BC–300 AD. Since the 1980s, scholars have argued that a period previously classified as a transition from the Jōmonball should be reclassified as Early Yayoi. The date of the beginning of this transition is controversial, with estimates ranging from the 10th to the 6th centuries BC.
