简介：Japan is not rich in iron resources, but because there is no coal, all the iron they have is made from charcoal. It has excellent iron properties and is perfect for making muskets. The reason why Ming swords are inferior to Japanese samurai swords is not because of technical problems. In the final analysis, it is because of iron quality.
