Ground furnace traces of iron production.

The 14th , Nagasaki Prefecture Iki City Board of Education has announced moat village remains of the Yayoi period " Karakami ruins " in ( Iki ) , the ground trace of furnace iron production has been found . Ground furnace remains of the Yayoi period of discovery for the first time in the country . Experts pointed out that there is a possibility of refining furnace that is not clearly identified in the Yayoi period , the city Board of Education to promote research in the future .
According to the city board of education , Roato a thing of the late Yayoi Period ( AD 1-3 century ) , six were found at least . Soil burnt in the range of about 80 cm in diameter on the floor and spread , was confirmed to make the furnace directly to the floor as " above-ground " .
Furnace have been identified in the country in the underground , furnace Karakami remains is similar to refining furnace trace can be seen in the ruins of Korea . Since the iron piece that occur when machining steel product is not found, that there may have been refined iron itself from the perimeter . It is refining of iron began around the late 6th century in Japan .
Miyamoto Professor of Kyushu University ( archeology ) , said " there is a possibility of refining furnace . And if so , an important archaeological sites had produced the iron in Yayoi era " and excavated from such situation .
In Karakami ruins , so far excavated iron rod and tube blowing air into the furnace , the iron as well as " arrowhead " . City Board of Education that " Did you process the iron has entered from the continent , or was refined here , you want to examine further " he said.
There is the Imperial City " Iki country " of which was written in the " Gishi Wajin den " and " Harunotsuji ruins " is Karakami ruins also was a village of  Iki .
History of smelting of iron might actually be largely rewritten . It might be that conveyed the technology people Iki , of the tri- system near the Korean peninsula is brought over from the Korean peninsula . Please complete the further research .




長崎県壱岐市教育委員会は14日、弥生時代の環濠集落跡「カラカミ遺跡」（壱岐市）で、鉄生産用の地上炉跡が見つかったと発表した。弥生時代の地上炉跡は国内で初めての発見。専門家は、弥生時代には明確に確認されていない精錬炉の可能性があると指摘、市教委は今後も調査を進める。
　市教委によると、炉跡は弥生時代後期（紀元１～３世紀ごろ）のもので、少なくとも６基が見つかった。床面に直径約80センチの範囲で焼けた土が広がっており、床面に直接炉を作る「地上式」と確認した。
　国内で確認されている炉は地下式で、カラカミ遺跡の炉は韓国の遺跡に見られる精錬炉跡に似ている。周辺からは鉄製品の加工時に発生する鉄片は見つかっていないため、鉄自体を精錬していた可能性があるという。日本では６世紀後半ごろ鉄の精錬が始まったとされている。
　九州大の宮本教授（考古学）は、出土状況などから「精錬炉の可能性がある。そうであれば、弥生時代に鉄を生産していた重要な遺跡だ」と述べている。
　これまでカラカミ遺跡では、炉に風を送る管や鉄の棒、鉄の「やじり」なども出土。市教委は「大陸から入った鉄を加工したか、ここで精錬したかは、さらに調べたい」としている。
　壱岐市には「魏志倭人伝」に記された「一支（いき）国」の王都とされる「原の辻遺跡」もあり、カラカミ遺跡も一支国の集落だったとされる。
　鉄の精錬の歴史が大きく書き換えられるかもしれませんね。韓半島に近い壱岐、渡来系の人々が韓半島から渡来して技術を伝えたのかもしれませんね。更なる調査研究を進めてください。
