Japan's energy security is one of the most important part of its security policy in general. Small energy resources made the Japa¬nese use imported ones, like oil and LNG more economically. In most part energy resources come form the Persian Gulf (oil) or from South-East Asia (LNG). The result is that the import can be thre¬atened by disturbance of the sea lines of communication. Other challenges, including cut-throat competition from PRC and India and reduced availability to the resources in general, help in developing alternative sources of energy or in promoting energy conservation.
