The japanese forging techniques were incredibly advanced, but japan is incredibly lacking in most forms of natural resources, especially coal and iron. I thought this was well known, and its detailed in a number of texts dealing with the japanese empire.solidstatemind said:Okay, I have to ask what is your source for this statement? Nothing I read in my studies, nor anything I have seen on the Internet has suggested that the ore in Japan was either terribly scarce or of lesser quality-- quite the opposite in fact: the Japanese pioneered several forging techniques which are still in use today.EMFCRACKSHOT said:As for the forging process, it is indeed different, due to the poor quality and scarcity of metal ores in japan.
The lengthy forging process and numerous foldings of the blade were designed to remove the impurities from the metal, producing steel that was comparable in quality to european steel.
lack of coal, iron ore etc was a key factor in the japanese expansion into china.
