Sorry for my comments. I think, it's good for us, Korean and japanese to communicate each other with brand-new informations on the excavations.
I think, the date of ผeขโี should be far back to the earlier days.In Korea, the remains such as ผeขโี was called Eฒ่`ฒE And as you know, in Eฒ่WใSE the narrow bronze dagger (ื`บ) was regarded as the typical symbol of the stage. Before then, the Lute type bronze dagger (๚i`บ) was used at that time, Eฒ่`ฒE So, the general pattern for the culture of Eฒ่WใSEwas very similar to those of middle age of the Yayoi period, and the scholars think that Eฒ่WใSEwas BC 300 to AD 0.
In Korea, the beginning of the Yoyoi culture seemed to have correlation with the Eฒ่`ฒ๎ศฐฬ at that stage, people used the bronze daggars, do the rice cultivation and used the plain potteries (ณถyํ). And the period of the Eฒ่`ฒEis thought to be BC 1000 or more to BC 300 in the case of the southern part of the Korean peninsula.
Recently, some archaeologist found the rice paddies even as early as BC 13 century, in the region adjacent to Puyo (v้P) (์ๅ p~แข).This means that the characteristics of the Korean bronze period, that is, using of the plain pottery, bronze tools, and the rice cultivation was establised much earlier than we think.
I think that ผeขโี could be dated back to much earlier times, because in the remains, the excavated bronze dagger was belonging to the oldest types even among the ๚i`บ.
So, some scholoars even thought that the date of the remains is likely to be BC 8C. this suggestion was supported by the various results using radioisotope tests.I think, BC 4C might be too conservative for the remains because at that period, ๚i`บ was not used even in the southern part of the Korean peninsula.
