Shinto - Buddhist synthesis -
In Japan long times ago, Buddhism which came from abroad, and Shinto, which is a folk religion, occasionally came together in a synthesis. Because Buddhism is not a theistic doctrine and Shinto principally worships nature, there are no contradictions in synthesizing them. This is called Shinbutsu-shugo.
This tendency continued for a long time after Buddhism was introduced in the 6 century, with Shinto shrine supporting the constriction of Buddhism temple. When Japan was began to function as modern nation state in 1868, Shinbutsu-shugo was prohibited because the government set a policy of strengthening Shinto, but now , it is quite common to set up both Buddhist family alters and Shinto family alters in the same house or to have wedding with Shinto rituals funerals with Buddhism rituals.
