Is Shintoism Japan's national religion?

Shintoism is the indigenous religion of Japan.
Influenced by Buddhism, Confucianism and Taoism, Shintoism later became ideologized.
In the Edo period, there was a view that encouraged the ancient faith in gods described in the Kojiki and the Nihon shoki.
This view, associated with the worship of the emperor as a descendant of the gods, developed into a movement to overthrow the Edo feudal government.
After the Meiji Restoration, Shintoism was protected by the State and the emperor became deified.
However, after World War II, the practice of religion was separated from the state, and Shintoism became just one of many religions in Japan.
