Paleolithic age of Japanese archipelago
About 20 thousand years ago, the earth was in the ice age, when the temperature was the lowest and the ground was covered with vast ice sheets.
At that time, the Japanese archipelago was still connected to the mainland, just on the other side of Hokkaido. Because of glaciers, the sea water is reduced, and the sea surface is about 100 meters lower than it is now. For example, the Strait of Ma is much narrower than it is now.
The average temperature is also seven degrees lower than now. It is said that the temperature in Japan at that time was about the same as that in Siberia now.
At that time, humans hunted mammoths, bighorn deer and other large animals. In some places in Nagano, Japan, a considerable number of mammoth fossils have also been unearthed, which are thought to be 50 thousand to 30 thousand years ago. At that time, humans probably came to the Japanese archipelago from the mainland because they chased animals.
At that time, people used stone tools, such as knives and cones, to hunt and live. For example, in hunting, a cone-shaped stone tool is tied to the front end of a wooden stick to make a simple javelin.
Later, with the gradual increase of the earth's temperature, Japan entered the rope age.
More rain and humid climate have formed a rich forest environment. In terms of food intake, there are also forest specialties such as pine cones, wild fruits and wild fungi. Moreover, hunting animals have changed from large animals to agile medium-sized animals such as deer, wild boar and birds. There is a saying that they were eaten and extinct. In short, in order to kill this small and agile animal, bows and arrows appeared. In addition, there are traps, traps and so on.
At that time, people still had a lot of food, not only nuts and wild fruits mentioned above, but also canoes made for fishing and shellfish in the water. Abundant mountain products and marine resources also make it unnecessary for human beings to maintain their lives through migration, and primitive villages were also formed during this period.
The primitive houses in Japan are called "living in vertical caves". In short, it is a semi-basement that is dug in the ground and then built with thatch around it.
There is also a very distinctive vessel called "pottery". Among them, the utensils used for processing food are inverted triangular utensils with thick top and thin bottom. The advantage is that it is heated more evenly in the fire, but it always looks unstable.
Speaking of "earthenware", the "rope writing" in the rope writing era was not tied on a rope (although I thought so before), but was printed on earthenware to form a pattern, which was generally considered as a sacrificial earthenware, and this pattern was not used at ordinary times.
The fire is in the middle of the "vertical cave" and then the food is cooked in the "earthen pot", which is just a feeling that modern people eat hot pot.
