Answer:
Japan considered raw materials to be important.
Japan depended on imports to obtain iron.
Japan ensured the security of trade routes.
Japan located major sources of iron in China.
Step-by-step explanation:
All these alternatives show that Japan used iron as a material of paramount importance for the industrial development of its economy. Thus, in considering the strategic need for industry raw materials, especially those that the country did not have, such as iron, Japan adopted trade strategies to ensure the supply of these inputs to its industry. This was done by mapping suppliers, such as China, and adopting and securing sea routes through which inputs and industrial production would flow into international trade.
