Why did japan fear new religion?

Answer 1

Japan's fear of new religions historically stemmed from concerns over social stability and political power. The introduction of foreign faiths, particularly Christianity during the 16th and 17th centuries, was perceived as a threat to the established social order and traditional beliefs, leading to fears of disunity and rebellion. Additionally, the potential for new religions to challenge the authority of the ruling shogunate heightened apprehensions, prompting measures such as persecution and isolation to maintain control and preserve cultural integrity.
