The religion of Shinto is very different from our own. Although its origins are unknown, it is the oldest religion in Japan and one of the eldest in the world. Shinto has shaped Japanese culture greatly since it’s first recording in 8th century CE by influencing their art, music, and education.
For example, one government has a strong allegiance to one particular religion, they will see other religious people’s views as a threat to political authority. This would only go to cause the state to overlook certain religions depending on their own faith.
