"Up north, south, left west, right east" is a common practice in world cartography, whether it is a paper map or a current electronic map follow this rule, but there is a place in the world where the map is reversed, it looks very different, that is, the Japanese Ministry of Defense. It is one of Japan's government departments and is in charge of defense affairs, acting as the ministry of defense of another country, with the top manager being the Minister of Defense. In the map used by the agency, the orientation of Japan and China has been reversed, and this is the only one that looks at the map in this way.
In the standard world map, Japan is located in the southeast direction of China, and Shanghai is the closest city to Japan, with a straight-line distance of only 690 kilometers. On the map, China looks like a big rooster, while Japan is a bug lying in front of the chicken's head, with the potential to swallow it up. Geographically, Japan is an island nation that has split off from Eurasia and drifted away from the continent as the plates drift. Culturally, Japan studied under the Sheng Tang Dynasty and still retains a large number of Chinese elements. In any case, Japan was suppressed in the southeast direction and could not move.
However, Japan was not willing to be suppressed by China, and after the Meiji Restoration, it quickly moved toward prosperity and strength, completed the capitalist transformation, and showed its fangs to its former teacher. Before the Sino-Japanese Sino-Japanese War, Japan intervened in the affairs of the Korean Peninsula and defeated the Qing government on both land and sea. During the Republic of China period, Japan first captured the three eastern provinces, entered the customs from north to south, and then attacked the interior from Shanghai along the Yangtze River. Under the heroic resistance of the Chinese people, the Japanese army stopped at the boundary of the second and third ladders, and surrendered after exhausting its national strength.
Although Japan was defeated, its ambitions were not dead, and it has not yet made a formal apology and economic compensation to the Chinese, and some right-wingers are still stirring up nationalist sentiments to summon the souls of War II war criminals. Reflected in its foreign strategy, Japan followed in the footsteps of the United States and laid two blockade lines along the southeast coast of China, calling it the "island chain." In the absence of the full development of our navy, submarines will be the main mode of warfare that our country will rely on for a long time in the future. Coincidentally, the direction of the Japanese Maritime Self-Defense Force is anti-submarine, and the four anti-submarine cruisers were also built for this purpose, and the purpose is self-evident.
Japan's north-south length is 4,000 kilometers, stretching our country from the south to the southern tip of Sakhalin Island in the north and almost leveling with Taiwan Island in the south, covering china's passage out of the Pacific Ocean tightly. Drawing a line from Sapporo to the Philippines almost completely covers the four major seas of our country, which is the "first island chain", and on the periphery there is the "second island chain" composed of Guam, Iwo Jima, Australia and New Zealand, and the two island chains lock our country on the west coast of the Pacific Ocean like chains. After the map was turned upside down, the sense of oppression brought about by the two island chains was particularly obvious, and the map of the eastern and central plains of our country was completely placed under the blow of Japan from south to north. China, which is accustomed to looking at maps from the north to the south, suddenly found that there was no danger in the "north" area, and a sense of crisis suddenly came.
