彌生時代
Archaeologists studying the history of the Japanese Archipelago separate the prehistoric history into three eras based on attributes of the discoveries associated with each era. The Jōmun period marks the first cases of pottery found on the archipelago, followed by the Yayoi period and the Kofun period. The Yayoi district of Tokyo, Japan is the namesake of the Yayoi period because archaeologists discovered pottery associated with the time period there.
