Sorry for asking again, but starting from 500 a. d. what were some of the natural resources of japan?

         Japan has significant coastal waters, which provide the country with fish and other seafood. However, the demand for fish is so high that it must be supplemented with imports from abroad. Although Japan has a small amount of arable land, the country has some of the highest crop yields in the world, producing over 60 percent of its own food each year. The country has adequate supplies of gold, silver, and magnesium, but it must import many of the minerals essential to its booming electronics industry, such as iron ore and copper.
