| 内容記述 | The Japanese archipelago is surrounded by the sea. This geographical factor by definition, greatly influences on the biological and physical environments and man's daily activities. But such marine conditions as surface temperature, salinity and currents have been subjected to change as the consequence of sea level fluctuations during the alternations of Glacial and Interglacial stages. This article attempts to clarify the relationships between those marine changes and the evolution of Japanese civilization and biological and physical environments since 50,000 years BP. An eco-historical study of the man and sea relationships explains the following characteristic historical "turnabouts" : Ca. 33,000 years BP. Before 33,000 years BP, the climate was cool and moist, with the increasingly elevated winter precipitation. Owing to heavy snowfall, glaciers developed in the high mountains. After 33,000 years BP the climate became cold and dry. The maximum cold epoch lasted from 21,000 to 18,000 years BP, and a dry climate prevailed. Snowfall on the Sea of Japan coast decreased to more than one-third of present precipitation. That decrease of winter precipitation was caused by a fall in sea level that weakened and sometimes interrupted the entrance of the warm Tsushima Current which promoted a heavy snowfall. In archaeological terms, the characteristic turnabout in the composition of stone implements occurred around 33,000 years BP. Before that time, choppers, chopping tools and handaxes were dominant elements of the stone implements, where- as after 33,000 years BP a new blade technique appeared. I suppose that this characteristic change of stone implements around 33,000 years BP was closely related with the environmental transition from an oceanic to a continental climate. Ca. 12,000 years BP. That was an opening epoch for the oceanic climate in Japan, during which the indication of increasing snowfall emerge. This climatic amelioration was caused by the beginning of entrance of the warm Tsushima Current into the Sea of Japan. But at that time the rise of sea-level was not enough to permit a full-scale entrance of the Tsushima Current that occured about 8,500 years BP. Corresponding with this start of the oceanic climate, around 12,000 years BP, the oldest earthernware appeared in southwestern Japan. It is noteworthy that the invention of this oldest earthernware coincides with the opening period of the oceanic climate. I conclude that the invention of earthernware in Japan arose when man's daily activities depended on the products of temperate broad-leaved forest which were suited to the oceanic climate. Ca. 2,500 years BP. The Jomon culture flourished under the warm climatic condition that lasted from 8,500 to 4,500 years BP. But after this warm epoch, the climate became cool and moist. Especially at about 2,500 years BP, there occurred one of the peaks of this late post-glacial climatic deterioration. One of the characteristic phenomena was that, the agricultural activity started in the midst of this climatic deterioration. The incidence of archaeological evidences of buckwheat cultivation by the Latest Jomon man increases after this climatic change. I suppose that this climatic deterioration in late postglacial time caused a southward migration of the human beings. People knowing the technique of buckwheat cultivation probably migrated southward, especially from the Manchuria, and arrived at the Japanese archipelago by passing through the Sea of Japan. |
