Surrender of Japan in the context of "Victory over Japan Day"

Taiwan, officially the Republic of China (ROC), is a country in East Asia. The main island of Taiwan, also known as Formosa, lies between the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. It has an area of 35,808 square kilometres (13,826 square miles), with mountain ranges dominating the eastern two-thirds and plains in the western third, where its highly urbanized population is concentrated. The combined territories under ROC control consist of 168 islands in total covering 36,193 square kilometres (13,974 square miles). The largest metropolitan area is formed by Taipei (the capital), New Taipei City, and Keelung. With around 23.9 million inhabitants, Taiwan is among the most densely populated countries.

Taiwan has been settled for at least 25,000 years. Ancestors of Taiwanese indigenous peoples settled the island around 6,000 years ago. In the 17th century, large-scale Han Chinese immigration began under Dutch colonial rule and continued under the Kingdom of Tungning, the first predominantly Han Chinese state in Taiwanese history. The island was annexed in 1683 by the Qing dynasty and ceded to the Empire of Japan in 1895. The Republic of China, which had overthrown the Qing in 1912 under the leadership of Sun Yat-sen, assumed control following the surrender of Japan in World War II. But with the loss of mainland China to the Communists in the Chinese Civil War, the government moved to Taiwan in 1949 under the Kuomintang (KMT).

Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. Its territory comprises one main island, 63 satellite islands and islets, and one outlying islet. The country is about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east and the Straits of Johor along with the State of Johor in Malaysia to the north.

In its early history, Singapore was a maritime emporium known as Temasek; subsequently, it was a major constituent of several successive thalassocratic empires. Its contemporary era began in 1819, when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, Singapore came under direct British control as part of the Straits Settlements. During World War II, Singapore was occupied by Japan in 1942 and returned to Britain as a Crown colony following Japan's surrender in 1945. Singapore gained self-governance in 1959 and in 1963 became part of the new federation of Malaysia, alongside Malaya, North Borneo and Sarawak. Ideological differences led to Singapore's expulsion from the federation two years later; it became an independent sovereign country in 1965. After early years of turbulence and despite lacking natural resources and a hinterland, the nation rapidly developed to become one of the Four Asian Tigers.

The division of Korea began at the end of World War II on 2 September 1945, with the establishment of a Soviet occupation zone and a US occupation zone. These zones developed into separate governments, named the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea), which fought a war from 1950 to 1953. Since then the division has continued.

By the early 20th century, both countries were one single nation: the Korean Empire. During World War II, the Allied leaders had already been considering the question of Korea's future following Japan's eventual surrender in the war. The leaders reached an understanding that Korea would be removed from Japanese control but would be placed under an international trusteeship until the Koreans would be deemed ready for self-rule. In the last days of the war, the United States proposed dividing the Korean peninsula into two occupation zones (a U.S. and Soviet one) with the 38th parallel as the dividing line. The Soviets accepted their proposal and agreed to divide Korea, which led to the declaration of General Order No. 1.

Japanese militarism (日本軍国主義, Nihon gunkoku shugi) was the ideology in the Empire of Japan which advocated the belief that militarism should dominate the political and social life of the nation, and the belief that the strength of the military is equal to the strength of a nation. It was most prominent from the start of conscription after the Meiji Restoration until the Japanese defeat in World War II, roughly 1873 to 1945. Since then, pacifism has been enshrined in the postwar Constitution of Japan as one of its key tenets.

The Constitution of Japan is the supreme law of Japan. Written primarily by American civilian officials during the occupation of Japan after World War II, it was adopted on 3 November 1946 and came into effect on 3 May 1947, succeeding the Meiji Constitution of 1889. The constitution consists of a preamble and 103 articles grouped into 11 chapters. It is based on the principles of popular sovereignty, with the Emperor of Japan as the symbol of the state; pacifism and the renunciation of war; and individual rights.

Upon the surrender of Japan at the end of the war in 1945, Japan was occupied and U.S. General Douglas MacArthur, the Supreme Commander for the Allied Powers, directed Prime Minister Kijūrō Shidehara to draft a new constitution. Shidehara created a committee of Japanese scholars for the task, but MacArthur reversed course in February 1946 and presented a draft created under his own supervision, which was reviewed and modified by the scholars before its adoption. Also known as the "MacArthur Constitution", "Post-war Constitution" (戦後憲法, Sengo-Kenpō), or "Peace Constitution" (平和憲法, Heiwa-Kenpō), it is relatively short at 5,000 signs, less than a quarter the length of the average national constitution if one compares it with constitutions written in alphabetical word-based languages.

The Bonin Islands, also known as the Ogasawara Islands (Japanese: 小笠原諸島), is a Japanese archipelago of over 30 subtropical and tropical islands located around 1,000 kilometers (620 mi) SSE of Tokyo and 1,600 kilometers (1,000 mi) northwest of Guam. The group as a whole has a total area of 84 square kilometers (32 sq mi) but only two of the islands are permanently inhabited, Chichijima and Hahajima. Together, their population was 2,560 as of 2021. Administratively, Tokyo's Ogasawara Subprefecture also includes the settlements on the Volcano Islands and the Self-Defense Force post on Iwo Jima. The seat of government is Chichijima.

Because of the Bonins' isolation, many of their animals and plants have undergone unique evolutionary processes. They have been referred to as the "Galápagos of the Orient" and were named a Natural World Heritage Site in 2011. When first reached during the early modern period, the islands were entirely uninhabited, although subsequent research has found evidence of some prehistoric habitation by Micronesians. Upon their repeated rediscoveries, the islands were largely ignored by the Spanish, Dutch, and isolationist Japanese until finally being claimed by a passing British captain in 1827. American, European, and Hawaiian colonists arrived from the Kingdom of Hawaii in 1830. Subsequently, Meiji Japan successfully colonized and reclaimed the islands in 1875, but Bonin Islanders' community continued up to World War II, when most islanders were forcibly relocated to Honshu. Following Japan's defeat, the U.S. Navy occupied the island, bulldozing existing Japanese homes and restricting resettlement until full control of the Bonins was returned to Japan in 1968. Ethnically, the island is now majority Japanese but remains unusually diverse, which is reflected in the local Creole language known as Bonin English. Improved transportation has made agriculture more profitable and encouraged tourism, but the development required for an airport remains a contentious local issue.

North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and borders China and Russia to the north at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone (DMZ). The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like South Korea, claims to be the sole legitimate government of the Korean Peninsula and adjacent islands. Pyongyang is the capital and largest city.

The Korean Peninsula was first inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Silla and Balhae in the late 7th century, Korea was ruled by the Goryeo dynasty (918–1392) and the Joseon dynasty (1392–1897). The succeeding Korean Empire (1897–1910) was annexed in 1910 into the Empire of Japan. In 1945, after the Japanese surrender at the end of World War II, Korea was divided into two zones along the 38th parallel, with the north occupied by the Soviet Union and the south occupied by the United States. In 1948, separate governments were formed in Korea: the socialist and Soviet-aligned Democratic People's Republic of Korea in the north, and the capitalist, Western-aligned Republic of Korea in the south. The North Korean invasion of South Korea in 1950 started the Korean War. In 1953, the Korean Armistice Agreement brought about a ceasefire and established a demilitarized zone (DMZ), but no formal peace treaty has ever been signed. Post-war North Korea benefited greatly from economic aid and expertise provided by other Eastern Bloc countries. However, Kim Il Sung, North Korea's first leader, promoted his personal philosophy of Juche as the state ideology. Pyongyang's international isolation sharply accelerated from the 1980s onwards as the Cold War came to an end. The fall of the Soviet Union in 1991 then brought about a sharp decline to the North Korean economy. From 1994 to 1998, North Korea suffered a famine with the population continuing to suffer from malnutrition. In 2024, the DPRK formally abandoned efforts to reunify Korea.

South Korea, officially the Republic of Korea (ROK), is a country in East Asia. It constitutes the southern half of the Korean Peninsula and borders North Korea along the Korean Demilitarized Zone, with the Yellow Sea to the west and the Sea of Japan to the east. Like North Korea, South Korea claims to be the sole legitimate government of the entire peninsula and adjacent islands. It has a population of about 52 million, of which half live in the Seoul metropolitan area, the ninth most populous metropolitan area in the world; other major cities include Busan, Daegu, and Incheon.

The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early seventh century BC. From the mid first century BC, various polities consolidated into the rival kingdoms of Goguryeo, Baekje, and Silla. The lattermost eventually unified most of the peninsula for the first time in the late seventh century AD, while Balhae succeeded Goguryeo in the north. The Goryeo dynasty (918–1392) achieved lasting unification and established the basis for the modern Korean identity. The subsequent Joseon dynasty (1392–1897) generated cultural, economic, and scientific achievements and also established isolationism starting from the mid-17th century. The succeeding Korean Empire (1897–1910) sought modernization and reform but was annexed in 1910 into the Empire of Japan. Japanese rule ended following Japan's surrender in World War II, after which Korea was divided into two zones: the Soviet-occupied northern zone and the United States-occupied southern zone. After negotiations on reunification failed, the southern zone became the Republic of Korea in August 1948, while the northern zone became the communist Democratic People's Republic of Korea the following month.

The Communist Party of China (CPC), commonly known as the Chinese Communist Party (CCP), is the founding and ruling party of the People's Republic of China (PRC). Founded in 1921, the CCP won the Chinese Civil War against the Kuomintang and proclaimed the establishment of the PRC under the chairmanship of Mao Zedong in October 1949. The CCP has since governed China and has had sole control over the country's armed forces and law enforcement. As of 2024, the CCP has more than 100 million members, making it the second largest political party by membership in the world.

In 1921, Chen Duxiu and Li Dazhao founded the CCP with the help of the Far Eastern Bureau of the Russian Communist Party (Bolsheviks) and Far Eastern Bureau of the Communist International. Although the CCP aligned with the Kuomintang (KMT) during its initial years, the rise of the KMT's right-wing under the leadership of Chiang Kai-shek and subsequent massacres of tens of thousands of CCP members resulted in a split and a prolonged civil war between the CCP and KMT. During the next ten years of guerrilla warfare, Mao Zedong rose to become the most influential figure in the CCP and the party established a strong base among the rural peasantry with its land reform policies. Support for the CCP continued to grow throughout the Second Sino-Japanese War. After the Japanese surrender in 1945, the CCP emerged triumphant in the communist revolution against the Nationalist government. The CCP established the People's Republic of China on 1 October 1949 and the remnants of the Nationalist government retreated to Taiwan shortly after.
