Japan has invaded many countries in its history, including China, North Korea, Russia, and the United States. Here is a brief explanation of the reasons for the aggression:
1.China: In the late 19th and early 20th centuries, Japan launched a war of aggression against China in order to obtain more resources and markets. In 1894, Japan launched the Sino-Japanese War, defeating the Qing Dynasty and forcing China to cede Taiwan, the Penghu Islands, and the Liaodong Peninsula. In 1931, Japan launched the "September 18 Incident", invaded and occupied Northeast China, and then invaded China in a full-scale manner until the victory of the War of Resistance against Japan in 1945.
2.Korea: In 1910, Japan formally annexed Korea and turned it into a colony. The Korean people suffered from Japanese colonial rule for a long time until Japan was defeated and surrendered in 1945.
3.Russia: In 1904, the Russo-Japanese War broke out between Japan and Russia over interests in northeastern China. After a series of battles, Japan emerged victorious, forcing Russia to recognize Japanese interests in Korea and northeastern China.
4.United States: On December 7, 1941, Japan attacked Pearl Harbor in the United States, leading to the United States' involvement in World War II. Japan's move is aimed at breaking the economic blockade imposed by the United States on it and ensuring its interests in Asia and the Pacific.
The main reasons for Japan's aggression against these countries include:
1.Resource needs: Japan is a small country with scarce resources, and in order to meet the needs of domestic economic development and population growth, Japan needs to seek external resources.
2.Market expansion: As Japan industrializes, it needs to find new markets to export goods and investment. Invading other countries can provide more markets and investment opportunities for Japanese companies.
3.Political Influence: Japan seeks to increase its position and influence in the international political arena through aggressive expansion.
4.Military Expansion: Japanese militarism prevailed, believing that through a war of aggression it was possible to demonstrate national strength and increase national pride.
5.Colonial rule: Japan believed that by annexing other countries and turning them into colonies, it could achieve the so-called "Greater East Asia Co-Prosperity Sphere" and achieve regional hegemony.
In short, Japan's aggressive behavior in history was mainly aimed at satisfying various needs such as resources, markets, politics, and military. However, this act of aggression has brought great suffering to the victim countries and regions, and has long condemned Japan in the international community.
