Greater East Asia Co-Prosperity Sphere

Greater East Asia Co-Prosperity Sphere was a pan-Asian concept and geopolitical entity created by Imperial Japan during World War II, aiming to unite East Asia and Southeast Asia under Japanese Empire leadership, with Tokyo as its capital, and Hirohito and Hideki Tojo as its key leaders, in collaboration with other Axis powers like Nazi Germany and Fascist Italy. The idea was heavily influenced by Japanese nationalism, Shintoism, and Bushido, as well as the works of Kita Ikki and Okawa Shumei, who were inspired by Sun Yat-sen and the Kuomintang. This concept was also linked to the Meiji Restoration and the Taisho period, which saw the rise of Japanese militarism and the invasion of Manchuria.

Concept and origins

The concept of the Greater East Asia Co-Prosperity Sphere was rooted in Japanese imperialism and the desire to expand Japan's influence in Asia, as seen in the First Sino-Japanese War and the Russo-Japanese War, with the support of Japanese politicians like Itō Hirobumi and Yamagata Aritomo. The idea was also influenced by the Washington Naval Conference and the London Naval Treaty, which limited Japan's naval power and led to the Japanese withdrawal from the League of Nations. The Second Sino-Japanese War and the Nanking Massacre further solidified Japan's aggressive expansion, with the Kwantung Army playing a key role, and the Soviet Union and Mongolia responding with the Battle of Khalkhin Gol. The Tripartite Pact with Germany and Italy marked a significant step towards the creation of the Greater East Asia Co-Prosperity Sphere, with Adolf Hitler and Benito Mussolini as key allies, and the Soviet–Japanese Neutrality Pact ensuring Japan's eastern border was secure.

Implementation and structure

The Greater East Asia Co-Prosperity Sphere was implemented through a series of military campaigns and diplomatic maneuvers, including the invasion of Indochina and the attack on Pearl Harbor, which drew United States, United Kingdom, and Netherlands into the conflict, with Franklin D. Roosevelt, Winston Churchill, and Queen Wilhelmina as key leaders. The Japanese government established the Greater East Asia Ministry to oversee the administration of the occupied territories, with Aoki Kazuo and Shigemitsu Mamoru as key officials, and the Imperial Japanese Army and Imperial Japanese Navy as the primary military forces. The Puppet states of Manchukuo, Wang Jingwei regime, and Thailand were also established, with Puyi and Wang Jingwei as key leaders, and the Indian National Army and Azad Hind as allies.

Economic and resource exploitation

The Greater East Asia Co-Prosperity Sphere was designed to exploit the natural resources of the occupied territories, including oil from Indonesia and Malaysia, rubber from Malaya and Indochina, and minerals from China and Korea, with the South Manchurian Railway and the North China Transportation Company as key infrastructure. The Japanese government also implemented a system of forced labor and requisitioning of local resources, with the Kempeitai and the Tokkeitai as key enforcers, and the Nanjing Treaty and the Treaty of Shimonoseki as key agreements. The Greater East Asia Co-Prosperity Sphere was also intended to create a self-sufficient economy for Japan, with the Yen bloc as a key component, and the Bank of Japan and the Bank of Korea as key financial institutions.

Propaganda and ideology

The Greater East Asia Co-Prosperity Sphere was promoted through a sophisticated propaganda campaign, which emphasized the idea of Asian solidarity and the need to liberate Asia from Western colonialism, with the Dōmei and the Taisei Yokusankai as key organizations, and Tokyo Radio and the Asahi Shimbun as key media outlets. The Japanese government also promoted the idea of Hakkō ichiu, or "all eight corners of the world under one roof," which emphasized the unity of Asia under Japanese leadership, with the Meiji Shrine and the Yasukuni Shrine as key symbols. The Greater East Asia Co-Prosperity Sphere was also linked to the Japanese concept of Kokutai, which emphasized the unique cultural and spiritual identity of Japan, with the Kokuryūkai and the Genyōsha as key organizations.

Opposition and resistance

The Greater East Asia Co-Prosperity Sphere faced significant opposition and resistance from various groups, including the Chinese Communist Party, the Kuomintang, and the Malayan Peoples' Anti-Japanese Army, with Mao Zedong, Chiang Kai-shek, and Chin Peng as key leaders. The Allies also launched a series of military campaigns against Japan, including the Guadalcanal campaign and the Philippines campaign, with Douglas MacArthur and Chester Nimitz as key commanders, and the Battle of Midway and the Battle of Leyte Gulf as key battles. The Soviet Union also declared war on Japan in 1945, with Joseph Stalin as the key leader, and the Battle of Manchuria as a key campaign.

Dissolution and legacy

The Greater East Asia Co-Prosperity Sphere was dissolved in 1945, following the defeat of Japan in World War II, with the Potsdam Declaration and the Japanese Instrument of Surrender as key documents, and the Occupation of Japan as a key consequence. The Treaty of San Francisco and the Treaty of Taipei marked the formal end of the Greater East Asia Co-Prosperity Sphere, with John Foster Dulles and Shigeru Yoshida as key negotiators, and the United Nations and the International Court of Justice as key institutions. The legacy of the Greater East Asia Co-Prosperity Sphere continues to be felt in East Asia and Southeast Asia, with ongoing debates over historical memory and war reparations, and the Asean and the East Asia Summit as key regional organizations.
