| Outline of Final Research Achievements |
Traditionally the process of metal diffusion and adoptions in northeast Asia had been considered as slow expansion of it from the center of civilization to its periphery. However, by applying new dating method, this model has been challenged and the results support that much more quick diffusion had been occurred. According to this change, not only the chronology of archaeological materials, but also the process of social changes has reconstructed. It is noteworthy that the characteristic stone weapons and ornaments that show local identities appeared in most of the area, corresponding to the approaching of the metal culture. This phenomenon is in some part common with that of in northwest Europe, which help us to understand the universality and diversity of metal adoption process in prehistoric societies.
