What is the religion of Japan?

The two main religions in Japan are Shintoism and Buddhism. Christianity is also practiced by a small portion of the population, and other religions are also present in smaller numbers. After Japan’s defeat in World War II, Emperor Hirohito renounced the divine character attributed to royalty by Shintoism, and the country’s new postwar constitution now upholds religious freedom for all Japanese citizens. According to the recent survey on percentages of religions in Japan, while many people say that their religions are Buddhism, high percentage of people think they are non-religious.

After several generations of deities born from the Cosmos itself, the last couple, Izanagi and Izanami, who played the role of creation in the Shinto tradition, finally emerged. The word Shinto, which can be translated to English as “the way of the gods”. When Shinto is written in Japanese, it consists of two ideograms. The first ideogram, which is also pronounced as kami, means god, deity, or divine power, and the second character means way or road.

Although the word, kami can be used to refer to a single god, it can also be used collectively to designate a group of gods. The kami are part of all life forms and manifest themselves in various forms. There are kami in nature that reside in sacred rocks, falls, rivers, trees, mountains, and in other natural phenomena. The absence of sacred writings in Shintoism reflects the lack of religious moral commandments, but emphasizes purity in ritual and the purification of those who practice it.
