Shintoism very widely spread religion in Japan. About 83% of the population in fact practices this religion. These practices follow an ancient culture that the Japanese are very proud of; the worship of ancient gods that is.
Japan is such a large population that it is difficult to know the exact amount of worshipers. But the sheer 83 % is enough to know just how much this religion is practiced and how well known it is. Of course this is only Japan, there are also areas in the world where a Torii Gate’s (Shinto’s religious symbol) and smaller shrines are placed.
