East Asia

East Asia is a geocultural region of Asia. It includes China, Japan, Mongolia, North Korea, South Korea, and Taiwan, plus two special administrative regions of China, Hong Kong and Macau. The economies of China, Japan, South Korea, and Taiwan are among the world's largest and most prosperous. East Asia borders North Asia to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To its east is the Pacific Ocean.

East Asia, especially Chinese civilization, is regarded as one of the earliest cradles of civilization. Other ancient civilizations in East Asia that still exist as independent countries in the present day include the Japanese, Korean, and Mongolian civilizations. Various other civilizations existed as independent polities in East Asia in the past but have since been absorbed into neighbouring civilizations in the present day, such as Tibet, Manchuria, and Ryukyu (Okinawa), among many others. Taiwan has a relatively young history in the region after the prehistoric era; originally, it was a major site of Austronesian civilisation prior to colonisation by European colonial powers and China from the 17th century onward. For thousands of years, China was the leading civilization in the region, exerting influence on its neighbours. Historically, societies in East Asia have fallen within the Chinese sphere of influence, and East Asian vocabularies and scripts are often derived from Classical Chinese and Chinese script. The Chinese calendar serves as the root from which many other East Asian calendars are derived.

Major religions in East Asia include Buddhism (mostly Mahayana), Confucianism and Neo-Confucianism, Taoism, ancestral worship, and Chinese folk religion in Mainland China, Hong Kong, Macau and Taiwan, Shinto in Japan, and Christianity and Musok in Korea. Tengerism and Tibetan Buddhism are prevalent among Mongols and Tibetans while other religions such as Shamanism are widespread among the indigenous populations of northeastern China such as the Manchus. The major languages in East Asia include Mandarin Chinese, Japanese, and Korean. The major ethnic groups of East Asia include the Han in China and Taiwan, Yamato in Japan, Koreans in North and South Korea, and Mongols in Mongolia. There are 76 officially-recognized minority or indigenous ethnic groups in East Asia; 55 native to mainland China (including Hui, Manchus, Chinese Mongols, Tibetans, Uyghurs, and Zhuang in the frontier regions), 16 native to the island of Taiwan (collectively known as Taiwanese indigenous peoples), one native to the major Japanese island of Hokkaido (the Ainu) and four native to Mongolia (Turkic peoples). The Ryukyuan people are an unrecognized ethnic group indigenous to the Ryukyu Islands in southern Japan, which stretch from Kyushu to Taiwan. There are also several unrecognized indigenous ethnic groups in mainland China and Taiwan.

East Asians comprise around 1.7 billion people, making up about 33% of the population in continental Asia and 20% of the global population.^{[needs update]} The region is home to major world metropolises such as Beijing–Tianjin, Busan–Daegu–Ulsan–Changwon, Guangzhou, Hong Kong, Osaka–Kyoto–Kobe, Seoul, Shanghai, Shenzhen, Taipei, and Tokyo. Although the coastal and riparian areas of the region form one of the world's most populated places, the population in Mongolia and Western China, both landlocked areas, is very sparsely distributed, with Mongolia having the lowest population density of a sovereign state. The overall population density of the region is 133 inhabitants per square kilometre (340/sq mi), about three times the world average of 45/km² (120/sq mi).^{[when?][citation needed]}

China was the first region settled in East Asia and was undoubtedly the core of East Asian civilization from where other parts of East Asia were formed. The various other regions in East Asia were selective in the Chinese influences they adopted into their local customs. Historian Ping-ti Ho referred to China as the cradle of Eastern civilization, in parallel with the cradle of Middle Eastern civilization along the Fertile Crescent encompassing Mesopotamia and Ancient Egypt as well as the cradle of Western civilization encompassing Ancient Greece.

Chinese civilization emerged early, and prefigured other East Asian civilisations. Throughout history, imperial China would exert cultural, economic, technological, and political influence on its neighbours. Succeeding Chinese dynasties exerted enormous influence across East Asia culturally, economically, politically and militarily for over two millennia. The tributary system of China shaped much of East Asia's history for over two millennia due to Imperial China's economic and cultural influence over the region, and thus played a huge role in the history of East Asia in particular. Imperial China's cultural preeminence not only led the country to become East Asia's first literate nation in the entire region, it also supplied Japan and Korea with Chinese loanwords and linguistic influences rooted in their writing systems.

Under Emperor Wu of Han, the Han dynasty made China the regional powerhouse in East Asia, projecting much of its imperial influence onto its neighbours. Han China hosted the largest unified population in East Asia, the most literate and urbanised as well as being the most economically developed, as well as the most technologically and culturally advanced civilization in the region at the time. Cultural and religious interaction between the Chinese and other regional East Asian dynasties and kingdoms occurred. China's impact and influence on Korea began with the Han dynasty's northeastern expansion in 108 BC when the Han Chinese conquered the northern part of the Korean peninsula and established a province called Lelang. Chinese influences were transmitted and soon took root in Korea through the inclusion of the Chinese writing system, monetary system, rice culture, philosophical schools of thought, and Confucian political institutions. Jomon society in ancient Japan incorporated wet-rice cultivation and metallurgy through its contact with Korea. Starting in the fourth century AD, Japan adopted Chinese characters, which remain integral to the Japanese writing system. Utilizing the Chinese writing system allowed the Japanese to conduct their daily activities, maintain historical records and give form to various ideas, thoughts, and philosophies.

During the Tang dynasty, China exerted its greatest influence on East Asia as various aspects of Chinese culture spread to Japan and Korea. The establishment of the medieval Tang dynasty rekindled the impetus of Chinese expansionism across the geopolitical confines of East Asia. Similar to its Han predecessor, Tang China reasserted itself as the center of East Asian geopolitical influence during the early medieval period which spearheaded and marked another golden age in Chinese history. During the Tang dynasty, China exerted its greatest influence on East Asia as various aspects of Chinese culture spread to Japan and Korea. In addition, Tang China also managed to maintain control over northern Vietnam and northern Korea.
