The history of East Asian religions in the United States is inextricably intertwined with the broader history of United States–East Asian relations, and specifically with U.S. imperialism. For most Americans in the 19th and into the early 20th centuries, information about religious life in China, Japan, and Korea came largely through foreign missionaries. A few prominent missionaries were deeply involved in the translation of important texts in East Asian religions and helped promote some understanding of these traditions. The majority of missionary writings, however, condemned the existing religions in these cultures as part of their critiques of the cultures as degenerate and in need of Christianity. In the late 19th and early 20th centuries, when the women’s foreign mission movement was the largest women’s movement in the United States, women missionaries’ representations of East Asian religions as inherent in the oppression of women particularly reached a large audience. There was also fascination with East Asian religions in the United States, especially as the 20th century progressed, and more translations appeared from people not connected to the foreign mission movement. By the 1920s, as “World Friendship” became an important paradigm in the foreign missionary movement, some missionary representations of East Asian religions became more positive, reflecting and contributing to a broader trend in the United States toward a greater interest in religious traditions around the world, and coinciding with a move toward secularization. As some scholars have suggested, the interest in East Asian religions in the United States in some ways fits into the framework of “Orientalism,” to use Edward Said’s famous term, viewing religions of the “East” as an exotic alternative to religion in the West. Other scholars have suggested that looking at the reception of these religions through a framework of “Orientalism” underestimates and distorts the impact these religious traditions have had in the United States. Regardless, religious traditions from East Asia have become a part of the American religious landscape, through both the practice of people who have immigrated from East Asia or practice the religion as they have learned from family members, and converts to those religions. The numbers of identified practitioners of East Asian religions in United States, with the exception of Buddhism, a religion that originated outside of East Asia, is extremely small, and even Buddhists are less than 2 percent of the American population. At the same time, some religious traditions, such as Daoism and some variants of Buddhism (most notably Zen Buddhism), have exercised a significant impact on popular culture, even while a clear understanding of these traditions has not yet been widespread in the United States. Some understanding of Confucianism as well has recently been spread through the propagation of “Confucian” institutes in the United States. It is through these institutes that we may see the beginnings of the Chinese government exercising some influence in American universities, which, while not comparable to the impact of Christian missionaries in the development of Chinese educational institutions in the late 19th and early 20th centuries, nonetheless can illuminate the growing power of China in Sino-American relations in the beginning of the 21st century.
While the term “East Asian” religions is frequently used for convenience, it is important to be aware of potential pitfalls in assigning labels such as “Western” and “Eastern” to religious traditions, particularly if this involves a construction of Christianity as inherently “Western.” At a time when South Korea sends the second largest number of Christian missionaries to other countries, Christianity could theoretically be defined as an East Asian religion, in that a significant number of people in one East Asian country not only practice but actively seek to propagate the religion. Terms such as “Eastern” and “Western” to define religious traditions are cultural constructs in and of themselves.
