Many people from overseas might have an idea that Japan is a Buddhist country.
Is it so?
The answer is Yes, but not really.
Buddhism was introduced to Japan from Korea (originally from India, through China) in the middle of 6th century.
But before that, Japanese people had long been polythestic, and worshiped "KAMI", gods and goddesses, and supernatural powers for more than 10,000 years. (it is proven by archeological discoveries)
This indigenous spiritual tradition is called "Shinto", or Shintoism.
Even today, there are more than 80,000 Shinto shrines all over Japan. Surprisingly, the number was over 20, 0000, before Meiji Restoration or Japan's modernization with Western influences from 1868.
