2. Japan is located on a narrow island, in the active zone of continental plate collision. It has been threatened by earthquakes and tsunamis for thousands of years. The deepest trench in the world is the Mariana Trench (with an average depth of 8,000 meters and only 200 kilometers away from the Japanese archipelago). Due to the push of the Asian continental plate and the retreat of the Pacific plate, it is expanding to the northeast at the rate of 10cm per year, that is, the Japanese archipelago in the Pacific Ocean. After the earthquake, scientists observed that the trench further accelerated its eastward expansion. The Japanese archipelago, located at the junction of the Pacific Ocean and Asia, is undoubtedly on the edge of the deepest funnel in the world! If there is an undersea earthquake similar to Indonesia once or twice, except for the Ryukyu Islands in the south, the Japanese islands are likely to face extinction and slide into the trench.
Because of this, the Japanese have a deep sense of crisis.
Therefore, Japan has established its own resource reserve system. Japan's fiscal reserves are quite abundant, and its foreign exchange reserves rank first in the world. At present, it has increased to more than 806 billion US dollars, and the gold reserve is also more than 654.38+004 billion US dollars. Material reserves include not only oil, natural gas, coal, uranium, steel and many rare metals, but also grains, wood, soybeans and animal feed. Japan's strategic reserve materials can be divided into legal reserves and arbitrary reserves, as well as national reserves and private enterprise reserves.
