Shinbutsu bunri in the context of "Pagoda"

Buddhism was first established in Japan in the 6th century CE. Most of the Japanese Buddhists belong to new schools of Buddhism which were established in the Kamakura period (1185－1333). During the Edo period (1603–1868), Buddhism was controlled by the feudal Shogunate. The Meiji period (1868–1912) saw a strong response against Buddhism, with persecution and a forced separation between Buddhism and Shinto (Shinbutsu bunri).

The largest sects of Japanese Buddhism are Pure Land Buddhism with 22 million believers, followed by Nichiren Buddhism with 10 million believers, Shingon Buddhism with 5.4 million, Zen Buddhism with 5.3 million, Tendai Buddhism with 2.8 million, and only about 700,000 for the six old schools established in the Nara period (710－794).

Shinbutsu-shūgō (神仏習合, "syncretism of kami and buddhas"), also called Shinbutsu-konkō (神仏混淆, "jumbling up" or "contamination of kami and buddhas"), is the syncretism of Shinto and Buddhism that was Japan's main organized religion up until the Meiji period. Beginning in 1868, the new Meiji government approved a series of laws that separated Japanese native kami worship, on one side, from Buddhism which had assimilated it, on the other.

When Buddhism was introduced from China in the Asuka period (6th century), the Japanese tried to reconcile the new beliefs with the older Shinto beliefs, assuming both were true. As a consequence, Buddhist temples (寺, tera) were attached to local Shinto shrines (神社, jinja) and vice versa and devoted to both kami and Buddhist figures. The local religion and foreign Buddhism never fused into a single, unified religion, but remained inextricably linked to the present day through interaction. The depth of the influence from Buddhism on local religious beliefs can be seen in much of Shinto's conceptual vocabulary and even the types of Shinto shrines seen today. The large worship halls and religious images are themselves of Buddhist origin. The formal separation of Buddhism from Shinto took place only as recently as the end of the 19th century; however, in many ways, the blending of the two still continues.

Gion worship (祇園信仰, Gion shinkō) is a Shinto cult. Originally it revolved solely around Gozu Tenno, but during the Separation of Shinto and Buddhism of the Meiji era the government mandated it shift to revolving around Susanoo.

The main shrines are Yasaka Shrine in Kyoto, Hiromine Shrine in Hyogo Prefecture, and Tsushima Shrine in Aichi Prefecture
