The human history of Japan dates back at least 30,000 years. At that point, the four main islands of Japan were connected and land bridges joined them to both Korea in the south and Siberia in the north. The first humans to occupy what is now Japan simply walked in.
While their stories remain in the archaeological record as flint tools and the remnants of settlements, we know almost nothing of their history. The development of writing tells us what the Japanese said about themselves. What little does emerge may be part-myth and part-truth, but it reveals a society often riven by war.
THE JOMON & THE YAYOI
The first culture to develop in Japan was the Jōmon around 10,000 BCE. We do not know what the Jōmon called themselves, but their name comes from their distinctive pottery style of intricately arranged cords, which archaeologists call Jōmon, meaning rope-patterned. Some of the pottery created by the later Jōmon would not look out of place in a modern art gallery. Their stylised pottery statues of people known as dogū so closely resemble spacemen in suits that some take them to be evidence of alien contact.
Contact with space aliens is unlikely, but when contact came between Japan and Asia it spelled the doom of the Jōmon people. Climate change around 1000 BCE saw them driven further south in Japan by cold weather. The Yayoi of China lived in a lush environment that dried out around the same time to create the Gobi desert of today. This destruction of their homelands caused a wave of migration. First settling in Korea, the Yayoi began migrating to Japan around 300 BCE. With their arrival, 10,000 years of Jōmon culture disappeared from the archaeological record.
Not much is known about the displacement of the Jōmon. Was it in a single wave of migration? Were they destroyed by warfare? The alternative is the Yayoi came in smaller numbers over a long period and integrated themselves.
