Religion in Japan is manifested primarily in Shinto and in Buddhism, the two main faiths, which Japanese people often practice simultaneously. According to estimates, as many as 80% of the populace follow Shinto rituals to some degree, worshiping ancestors and spirits at domestic altars and public shrines. An almost equally high number is reported as Buddhist. Syncretic combinations of both, known generally as shinbutsu-shūgō, are common; they represented Japan's dominant religion before the rise of State Shinto in the 19th century.
The People's Republic of China is officially an atheist state, but the government formally recognizes five religions: Buddhism, Taoism, Christianity, and Islam. In the early 21st century, there has been increasing official recognition of Confucianism and Chinese folk religion as part of China's cultural inheritance. Chinese civilization has historically long been a cradle and host to a variety of the most enduring religio-philosophical traditions of the world. Confucianism and Taoism (Daoism), later joined by Buddhism, constitute the "three teachings" that have shaped Chinese culture. There are no clear boundaries between these intertwined religious systems, which do not claim to be exclusive, and elements of each enrich popular or folk religion. The emperors of China claimed the Mandate of Heaven and participated in Chinese religious practices. In the early 20th century, reform-minded officials and intellectuals attacked all religions as "superstitious"; since 1949, China has been governed by the CCP, a Marxist–Leninist atheist institution that prohibits party members from practicing religion while in office. In the culmination of a series of atheistic and anti-religious campaigns already underway since the late 19th century, the Cultural Revolution against old habits, ideas, customs, and culture, lasting from 1966 to 1976, destroyed or forced them underground. Under subsequent leaders, religious organisations have been given more autonomy.
Chinese folk religion, also known as Chinese popular religion comprehends a range of traditional religious practices of Han Chinese, including the Chinese diaspora. Vivienne Wee described it as "an empty bowl, which can variously be filled with the contents of institutionalised religions such as Buddhism, Taoism, Confucianism and Chinese syncretic religions”. This includes the veneration of shen (spirits) and ancestors, exorcism of demonic forces, and a belief in the rational order of nature, balance in the universe and reality that can be influenced by human beings and their rulers, as well as spirits and gods. Worship is devoted to gods and immortals, who can be deities of places or natural phenomena, of human behaviour, or founders of family lineages. Stories of these gods are collected into the body of Chinese mythology. By the Song dynasty (960-1279), these practices had been blended with Buddhist doctrines and Taoist teachings to form the popular religious system which has lasted in many ways until the present day. The present day government of mainland China, like the imperial dynasties, tolerates popular religious organizations if they bolster social stability but suppresses or persecutes those that they fear would undermine it.
The Eastern religions are the religions which originated in East, South and Southeast Asia and thus have dissimilarities with Western, African and Iranian religions. This includes the East Asian religions such as Confucianism, Taoism, Chinese folk religion, Shinto, and Korean Shamanism; South Asian religions such as Hinduism, Buddhism, Jainism, and Sikhism; and Southeast Asian religions such as Vietnamese folk religion as well as animistic indigenous religions.
Throughout the ages, there have been various popular religious traditions practiced on the Korean peninsula. The oldest indigenous religion of Korea is the Korean folk religion, which has been passed down from prehistory to the present. Buddhism was introduced to Korea from China during the Three Kingdoms era in the fourth century, and the religion pervaded the culture until the Joseon Dynasty when Confucianism was established as the state philosophy. During the Late Joseon Dynasty, in the 19th century, Christianity began to gain a foothold in Korea. While both Christianity and Buddhism would play important roles in the resistance to the Japanese occupation of Korea in the first half of the 20th century, only about 4% of Koreans were members of a religious organization in 1940.
Kejawèn or Javanism, also called Kebatinan, Agama Jawa, and Kepercayaan, is a Javanese religious tradition, consisting of an amalgam of animistic, Buddhist, and Hindu aspects. It is rooted in Javanese history and religiosity, syncretizing aspects of different religions.
The majority of Vietnamese do not follow any organized religion, instead participating in one or more practices of folk religions, such as venerating ancestors, or praying to deities, especially during Tết and other festivals. Folk religions were founded on endemic cultural beliefs that were historically affected by Confucianism and Taoism from China, as well as by various strands of Buddhism. These three teachings or tam giáo were later joined by Christianity which has become a significant presence. Vietnam is also home of two indigenous religions: syncretic Caodaism and quasi-Buddhist Hoahaoism.
Buddhism has interacted with several Eastern religions such as Taoism, Shinto and Bon since it spread from the Indian subcontinent during the 2nd century AD.
Asia is the largest and most populous continent and the birthplace of many religions including Buddhism, Christianity, Confucianism, Hinduism, Islam, Jainism, Judaism, Shinto, Sikhism, Taoism, and Zoroastrianism. All major religious traditions are practiced in the region and new forms are constantly emerging. Asia is noted for its diversity of culture. Islam and Hinduism are the largest religions in Asia with approximately 1.2 billion adherents each.
Taoism or "Do" is thought to be the earliest state philosophy for the Korean people. However, its influence waned with the introduction of Buddhism during the Goryeo kingdom as the national religion and the dominance of neo-Confucianism during the Joseon dynasty. Despite its diminished influence during those periods, it permeated all strata of the Korean populace, integrating with its native animism as well as Buddhist and Confucian institutions, temples, and ceremonies. The Taoist practice in Korea developed, somewhat in contrast to China, as an esoteric meditative practice in the mountains taught by the "mountain masters" or "mountain sages".
Religion in Taiwan is characterised by a diversity of religious beliefs and practices, predominantly those pertaining to the continued preservation of the ancient Chinese culture and religion. Freedom of religion is inscribed in the constitution of the Republic of China (Taiwan), and ranks high at 9.2 on the Freedom Scale in 2018 according to the World Bank. The majority of Taiwanese people practice a combination of Buddhism and Taoism often with a Confucian worldview, which is collectively termed as Chinese folk religion.
In the study of comparative religion, the East Asian religions or Taoic religions, form a subset of the Eastern religions. This group includes Chinese religion overall, which further includes Ancestral Worship, Chinese folk religion, Confucianism, Taoism and popular salvationist organisations, as well as elements drawn from Mahayana Buddhism that form the core of Chinese and East Asian Buddhism at large. The group also includes Japanese Shinto, Tenrikyo, and Korean Muism, all of which combine Shamanistic elements and indigenous ancestral worship with various influences from Chinese religions. Chinese salvationist religions have influenced the rise of Japanese new religions such Tenriism and Korean Jeungsanism; as these new religious movements draw upon indigenous traditions but are heavily influenced by Chinese philosophy and theology.
Malaysian folk religion refers to the animistic and polytheistic beliefs and practices that are still held by many in the Islamic-majority country of Malaysia. Malaysian folk faith is practiced either openly or covertly depending on the type of rituals performed.
The Tai folk religion, or Satsana Phi, or Ban Phi is a form of animist religious beliefs intermixed with Buddhist beliefs traditionally and historically practiced by groups of ethnic Tai peoples. It is a syncretic mixture of Buddhist and Hindu practices with local traditional beliefs in mainland southeast Asia. Tai folk religion was a dominant native religion in mainland Southeast Asia until the arrival of Buddhism and Hinduism.
Polytheism is the belief in multiple deities, which are usually assembled into a pantheon of gods and goddesses, along with their own religious sects and rituals. Polytheism is a type of theism. Within theism, it contrasts with monotheism, the belief in a singular God who is, in most cases, transcendent. In religions that accept polytheism, the different gods and goddesses may be representations of forces of nature or ancestral principles; they can be viewed either as autonomous or as aspects or emanations of a creator deity or transcendental absolute principle, which manifests immanently in nature. Polytheists do not always worship all the gods equally; they can be henotheists, specializing in the worship of one particular deity, or kathenotheists, worshiping different deities at different times.
Chinese ancestor veneration, also called Chinese ancestor worship, is an aspect of the Chinese traditional religion which revolves around the ritual celebration of the deified ancestors and tutelary deities of people with the same surname organised into lineage societies in ancestral shrines. Ancestors, their ghosts, or spirits, and gods are considered part of "this world". They are neither supernatural nor transcendent in the sense of being beyond nature. The ancestors are humans who have become godly beings, beings who keep their individual identities. For this reason, Chinese religion is founded on veneration of ancestors. Ancestors are believed to be a means of connection to the supreme power of Tian as they are considered embodiments or reproducers of the creative order of Heaven. It is a major aspect of Han Chinese religion, but the custom has also spread to ethnic minority groups.
In religious studies and folkloristics, folk religion, popular religion, traditional religion or vernacular religion comprises various forms and expressions of religion that are distinct from the official doctrines and practices of organized religion. The precise definition of folk religion varies among scholars. Sometimes also termed popular belief, it consists of ethnic or regional religious customs under the umbrella of a religion, but outside official doctrine and practices.
Northeast China folk religion is the variety of Chinese folk religion of northeast China, characterised by distinctive cults original to Hebei and Shandong, transplanted and adapted by the Han Chinese settlers of Liaoning, Jilin and Heilongjiang since the Qing dynasty. It is characterised by terminology, deities and practices that are different from those of central and southern Chinese folk religion. Many of these patterns derive from the interaction of Han religion with Manchu shamanism.
Religious syncretism is the blending of religious belief systems into a new system, or the incorporation of other beliefs into a religious tradition.
