Japan has an eclectic and ecumenical approach to religion, with many seemingly incompatible beliefs mixed together or existing side by side. When you visit Japan, you’ll see many places of worship that reflect the respective religious traditions. Here we take a look at the main Japanese religions.
Shintō
Shintō represents the indigenous animistic belief system of the Japanese archipelago, evolving over millennia without a central founder or written scripture. Its earliest practices take the form of local nature worship, where spirits known as kami reside within natural structures like mountains, trees, and waterfalls. The English name for Shintō places of worship is ‘shrine’ (jinja). By the late fifth century, local clans used Shintō beliefs to legitimize their authority, culminating in the imperial lineage claiming direct descent from the sun deity Amaterasu. Large sacred sites such as Konpira Shrine were the object of pilgrimages during the Edo Period. Shintō shifted significantly in 1868 during the Meiji Restoration, when the state forcibly separated it from Buddhism to establish State Shintō as an ideological instrument of national unity and imperial devotion. Post-war reforms dismantled state control, turning shrines into independent religious corporations. Unlike standard religious models, Shintō doesn’t require exclusive membership or moral dogma. It functions as a collection of ritual purifications, seasonal festivals, and local community rites to maintain harmony between humans and nature.
Buddhism
Buddhism is a practice that originated in northern India and travelled south. The English name for Buddhist places of worship is ‘temple’ (o-tera). Buddhism arrived in Japan from the Korean kingdom of Baekje around 538, triggering political conflict before securing imperial patronage. Over the following centuries, various Chinese sects adapted to Japanese culture, generating distinct traditions. The early Heian period saw the establishment of Tendai and Shingon esoteric Buddhism in the ninth century, imported by the monks Saichō and Kūkai. Shingon introduced elaborate esoteric rituals and mandala imagery, asserting that enlightenment could be achieved in one’s current physical body. The Shikoku Pilgrimage associated with Kūkai has endured for centuries. During the unstable Kamakura period in the twelfth and thirteenth centuries, Buddhism expanded beyond the aristocracy. Pure Land Buddhism (Jōdo-shū and Jōdo Shinshū), founded by Hōnen and Shinran, simplified practice to the repetition of the chant Namu Amida Butsu, offering universal salvation. Zen Buddhism (Rinzai and Sōtō), imported from China by Eisai and Dōgen, emphasized strict seated meditation (zazen) and martial discipline, gaining rapid support among the ruling samurai class. Japanese Buddhism diverged sharply from its Asian mainland counterparts during the Meiji era, when legal mandates permitted priests to marry, eat meat, and pass temple leadership through hereditary succession. This liberalisation occurred after the sometimes violent separation of Shintō and Buddhism in the early Meiji period.
Shugendō
Shugendō is a syncretic, mountain-dwelling spiritual tradition that emerged around the seventh century, traditionally attributed to the legendary mystic En no Gyōja. It fuses pre-Buddhist Shintō nature and mountain worship with Esoteric Buddhism (Shingon and Tendai), Taoist magic, and local shamanism. Practitioners, known as yamabushi (“those who lie in the mountains”), view rugged mountain peaks as living mandalas and physical manifestations of Buddhist deities. Rather than focusing on textual study or temple doctrines, Shugendō emphasizes rigorous ascetic training (shugyō) in the wilderness—including cold-water purification beneath freezing waterfalls, hanging over cliff edges, and endurance marches across dangerous mountain peaks—to cultivate supernatural spiritual power and achieve enlightenment within one’s physical body. Shugendō practitioners worship at both shrines and temples. During the Meiji period, the government outlawed Shugendō in 1872 as part of its effort to forcibly separate Shintō and Buddhism. Despite this suppression, the tradition survived by affiliating with established Tendai and Shingon temples, and it experienced a resurgence in the post-war period. Today, active mountain pilgrimages continue in sacred ranges such as Mt. Haguro in Yamagata, the Mt. Ōmine region in Nara, and Mt. Ishizuchi on Shikoku.
Christianity
Christianity entered Japan in 1549 with the Portuguese Jesuit missionary Francis Xavier. It expanded rapidly in western Kyūshū, securing roughly 300,000 converts before the Tokugawa shogunate issued a complete ban in 1614, perceiving the foreign faith as a precursor to European colonization. Believers maintained their faith through underground networks known as Hidden Christians (kakure kirishitan), adapting their rituals to avoid detection. They disguised Christian iconography as traditional imagery, carving statues of the Virgin Mary to resemble the Buddhist deity Kannon, and passed down oral prayers called orasho across generations without written texts or ordained priests. When Japan reopened its borders in the mid-nineteenth century and lifted the ban on Christianity, these communities emerged with practices that had evolved into a distinct syncretic tradition, separate from both Roman Catholicism and mainstream Protestantism. Today, Christians account for less than one percent of Japan’s domestic population, yet Christian-style wedding ceremonies remain popular across the country. Christians worship in a ‘church’ (kyōkai).
New religions
The mid-nineteenth century marked the emergence of shinshūkyō, or new religious movements, triggered by the social upheaval of Japan’s rapid modernization. Early groups such as Tenrikyō, founded in 1838 by Nakayama Miki, and Ōmoto, established in 1892 by Deguchi Nao, originated from charismatic figures who claimed direct divine revelation. These organizations combined elements of Shintō folk belief, ancestor worship, and faith healing, offering structured communities during periods of urban migration. Tenrikyō worships in temple-like buildings known as ‘churches’ (kyōkai).
In the post-war era, Sōka Gakkai emerged as a prominent lay organisation rooted in the thirteenth-century Nichiren Buddhist tradition. It grew by focusing on daily chanting, active proselytizing, and community network building. Practitioners worship in dedicated community centres and private homes. Sōka Gakkai eventually founded its own national political party, Kōmeitō, which has served as a coalition partner in the Japanese government for decades.
Cults
The late twentieth century saw the emergence of shin-shinshūkyō, or secondary new religions, which integrated modern media, pop culture, and apocalyptic doctrines. Founded in 1986 by Ōkawa Ryūhō, Happy Science (Kōfuku-no-Kagaku) blends elements of various global religions, new-age philosophy, and belief in spirit communication. The organization operates its own political arm, the Happiness Realization Party, and publishes literature claiming its leader channels messages from historical figures. In contrast, Aum Shinrikyō, established by Matsumoto Chizuo (cult name: Asahara Shōkō) in 1987, combined Esoteric Buddhist terminology, yoga, and apocalyptic prophecy. The group recruited young scientists and university graduates before committing the March 1995 sarin gas attack on the Tokyo subway system. Despite the subsequent execution of its leadership and severe legal restrictions, splinter factions like Aleph and Hikari no Wa continue to operate under strict government surveillance.
Foreign-founded religious movements have also established significant footholds in post-war Japan. The Family Federation for World Peace and Unification, commonly known as the Unification Church, was founded in South Korea in 1954 by Moon Sun Myung and expanded into Japan during the late 1950s. The organization drew widespread scrutiny for its aggressive fundraising methods, spiritual sales tactics (insekkyō), and mass arranged marriages. Japan became the primary source of global revenue for the movement, funding its political lobbying efforts and international operations. The group’s deep ties to high-ranking politicians within the ruling Liberal Democratic Party came under intense public investigation following the 2022 assassination of former Prime Minister Abe Shinzo. This event led to government audits, legal reforms targeting predatory donation practices, and formal court requests to dissolve the church’s status as a tax-exempt religious corporation in Japan.
