What was the Greater East Asia Co-Prosperity Sphere?
The Greater East Asia Co-Prosperity Sphere (GEACPS) was Japan's concept during World War II of an Asia-Pacific bloc under its control. Announced in 1940, it promoted the idea of "Asia for Asians," envisioning a unified economic, political, and military entity.
Japan aimed to exclude both European imperialism and communist influence, but in reality, Japan exploited many countries within the GEACPS for its war effort. The GEACPS included areas such as Korea, Manchuria, parts of China, French Indochina, and other territories. Japan imposed its culture and language, controlled governments, and exploited resources, causing widespread suffering. The GEACPS ultimately collapsed with Japan’s surrender in 1945.

Which countries and regions did Japan include in the Co-Prosperity Sphere?
The Greater East Asia Co-Prosperity Sphere (GEACPS) was Japan's concept for a self-sufficient bloc in the Asia-Pacific region during World War II. Announced in 1940, it promoted "Asia for Asians" to exclude European imperialism and communist influence, envisioning a unified economic, political, and military zone.
The GEACPS included Korea, Manchukuo (Japanese-controlled Manchuria), parts of China, French Indochina, the Philippines, Singapore, the Dutch East Indies, Thailand, and other Asian countries and territories, as well as parts of the Pacific Islands region. Japan exploited these countries for its war effort, extracting resources and controlling governments, leading to widespread suffering. The GEACPS collapsed with Japan's surrender in 1945.

Why did Japan create the Greater East Asia Co-Prosperity Sphere during World War II?
During World War II, Japan created the Greater East Asia Co-Prosperity Sphere (GEACPS) to unify the Asia-Pacific region under its control. Japan aimed to establish political and industrial dominance while excluding European imperialism and communist influence, using the slogan "Asia for Asians".
The GEACPS arose from Japan's imperialistic goals to secure resources, expand its territory and military, and grow its economy. Japanese leaders believed they were treated unfairly by Westerners due to racial prejudice and resented Western colonization and discriminatory laws against Asians. Japan sought recognition as an equal power after the Meiji Restoration but felt slighted during the Paris Peace Conference after World War I, which further motivated their pursuit of regional dominance. Despite its rhetoric, Japan exploited the resources and people within the GEACPS for its war efforts until its surrender in 1945.

How did the Japanese colonial order affect the daily lives of people in the occupied countries?
During World War II, Japan introduced the Greater East Asia Co-Prosperity Sphere (GEACPS) as a self-sufficient bloc in the Asia-Pacific region under its control, using the slogan "Asia for Asians". However, Japan exploited many countries within the GEACPS for its war effort.
Japan imposed its culture by mandating Japanese as the official language, sending teachers to instill respect for the Japanese emperor, and forcing people to pray at Shinto shrines. Japan also took control of governments, with declared independent countries becoming Japanese puppet states. The Japanese military maintained order, committing atrocities, while propaganda portrayed them as heroic liberators.
The GEACPS served as Japan's economic backbone, exploiting human and natural resources. Civilians were forced to work in arms factories, and countries were compelled to ship agricultural produce to Japan. Natural resources were extracted to supply Japan's war effort, causing widespread terror and suffering for millions.

What methods did Japan use to control and govern the countries in the Co-Prosperity Sphere?
Japan's control over the Greater East Asia Co-Prosperity Sphere (GEACPS) during World War II involved political, cultural, and economic dominance.
Japan imposed its culture by mandating Japanese as the official language, sending teachers to instill respect for the emperor, and forcing prayers at Shinto shrines. Militarily, Japan maintained order through its forces, suppressing dissent with atrocities while portraying themselves as liberators in propaganda.
Economically, the GEACPS served as Japan's backbone, exploiting resources and controlling trade to benefit its war efforts. This extractive colonialism led to widespread suffering within the sphere, ending only with Japan's surrender in 1945.

How did people in the occupied countries respond to Japanese rule and what were some lasting effects?
In Japanese-occupied territories within the Greater East Asia Co-Prosperity Sphere, responses varied from collaboration to resistance. Some leaders initially saw Japan's arrival in Southeast Asia in 1941–42 as an opportunity for independence, while many intellectuals quickly realized it was a "more formidable and ferocious, version of colonial rule".
Japan mobilized local populations for the war effort but faced resistance due to the imposition of Japanese models, leading to disorder and anti-Japanese sentiment. The educated elite gained positions of authority but were restricted.
The occupation had lasting effects, destroying the mystique of Western supremacy but failing to replace it with a Japanese one. Despite complaints of Japanese fascism influencing societies, evidence suggests that Southeast Asians only adopted Japanese concepts when they could be thoroughly integrated locally. The war also ruined any chances that it might be replaced with a Japanese mystique.

Greater East Asia Co-Prosperity Sphere (GEACPS), during World War II (1939–45), the Japanese concept of a unified and self-sufficient bloc in the Asia-Pacific region under Japanese control. It was to be Japan’s ideological new order, which would amount to a self-contained empire stretching from Manchuria to the Dutch East Indies and including China, French Indochina, Thailand, and British Malaya as satellite states. Under the slogan “Asia for Asians,” Japan intended to ensure its political and industrial hegemony over the region while excluding from it both European imperialism and communist influence. In reality, many countries within the GEACPS were exploited by Japan for its war effort. The GEACPS collapsed with Japan’s surrender to the Allied powers in September 1945.
Background
The idea of the GEACPS developed from a series of issues. Japanese leaders had an imperialistic interest in securing natural resources and expanding Japan’s territory, military, and economy. In addition, they believed that Westerners treated the Japanese unfairly, out of racial and ethnic prejudice against Asians, and they resented the Western colonization of Asian countries as well as the discriminatory laws and sentiments against Asians in the United States and other Western countries. Since the Meiji Restoration, a political revolution in 1868 that brought about the modernization and Westernization of Japan, Japanese leaders had sought recognition of their country as a power equal to Western countries. However, the treatment that Japan received from the Western powers during negotiations at the Paris Peace Conference—the meeting that inaugurated the international settlement after World War I—further convinced Japanese leaders that their country was not being regarded as an equal.
Japan had entered World War I in 1914 on the side of the Allied powers, and it had primarily fought German naval forces and captured German-controlled territories in the Asia-Pacific region. Japanese leaders’ primary goals were to expand Japan’s power in that region and to gain the country recognition as an equal of the Western powers. After the Allies won the war in 1918, Japanese leaders expected their country to be rewarded. However, Japan’s representatives at the Paris Peace Conference achieved far less than they had hoped and found themselves being treated unfairly vis-à-vis their Western peers. Whereas they had expected to secure all the formerly German-controlled territories in the Asia-Pacific, they secured only some of them. New Zealand, Australia, and Great Britain gained the other German concessions.

In addition, Japan’s representatives proposed a “racial equality clause” to be included in the covenant of the League of Nations, which was also under negotiation at the conference. The clause stated that all countries, regardless of the race of their people, were equal. This was a Japanese effort to secure recognition of Japan’s equal footing with Western countries. Although the majority of the negotiating parties supported the clause, it was ultimately rejected by the conference chair, U.S. Pres. Woodrow Wilson, ostensibly because the vote in favour of it had not been unanimous. The rejection of the racial equality proposal, as well as Japanese disappointment at not receiving more territorial spoils, played a part in Japanese leaders’ conclusion that their goal of increasing Japan’s influence would be best served by dominating the Asia-Pacific.
Overview
The GEACPS was formally announced to the public by the Japanese foreign minister Yōsuke Matsuoka in August 1940. In the announcement, he introduced the idea of “Asia for Asians,” which entailed the economic, political, and military unification of Asia. Scholars have since observed the similarity of the GEACPS to the Monroe Doctrine: just as that statement of U.S. foreign policy, proclaimed in 1823, included a prohibition of further colonization in the Western Hemisphere, the GEACPS concept sought to end the era of Western colonization in the Asia-Pacific.
As Japanese forces invaded and conquered more and more countries and territories in that region, the GEACPS came to include Korea, Manchukuo (Japanese-controlled Manchuria), parts of China, French Indochina, the Philippines, Singapore, the Dutch East Indies, Thailand, and other countries and territories in Asia as well as parts of the Pacific Islands region.
In November 1943 Tokyo hosted an international summit called the Greater East Asia Conference, which was attended by representatives from puppet regimes in Japanese-occupied countries and territories, such as prime ministers from Manchukuo and Burma. At the conclusion of the conference, a joint declaration with five points was announced. The GEACPS countries were to (1) cooperate to ensure the stability of their region, (2) respect the sovereignty and independence of each participating country, (3) respect one another’s traditions and cultures, (4) cooperate for economic development and prosperity, and (5) work to establish friendly relations with other countries around the world. While this declaration was designed to appear beneficial for all parties, in actuality Japan dominated the GEACPS and engaged in extractive colonialism.

Japan justified its dominant position within the sphere by claiming that the Japanese people were racially superior. For this reason, despite the 1943 joint declaration of respect for the sovereignty and independence of each participating country, Japan imposed its culture on the rest of the sphere. For instance, it mandated Japanese as the official language of the GEACPS, it sent Japanese teachers to the other countries to teach Japanese culture and instill respect for the Japanese emperor, and it often forced non-Japanese people to pray for Japan’s success at Shinto shrines.
In addition to imposing its culture on other countries within the bloc, Japan took control of each country’s government. Countries that Japan declared to be independent, such as Burma and the Philippines in 1943, were actually Japanese puppet states. Japanese leaders sent their military forces to countries within the sphere to maintain order. Despite the atrocities those forces were committing in the areas they occupied, including widespread torture, rape, and mass killings, the Japanese-controlled mass media sector produced propaganda, such as films and print materials, that often portrayed the Japanese as heroic figures—indeed, as liberators of the Asia-Pacific from Western colonialists.
During World War II, Japan used the GEACPS as an economic backbone. Primarily to serve its own interests, it oversaw trade, manufacturing, and financial and monetary affairs within the bloc. It also exploited the GEACPS countries’ human and natural resources. For instance, it forced non-Japanese civilians to work in factories that produced arms for Japan’s military, and it compelled member countries to ship much of their agricultural produce to Japan. In addition, it had natural resources like iron ore, rubber, oil, and coal extracted from GEACPS countries and sent to Japan to supply its war effort.
In the process, millions of people within the sphere experienced widespread terror and suffering. With the Japanese surrender to the Allies on September 2, 1945, the GEACPS collapsed.
