The second biggest religion in this country is the Christianity.
While it is not as big as Buddhism, a lot of people have faith in Christianity.
For those who don’t follow either Buddhism or Christianity, it is common that they are born as Buddhists and have a Christian style wedding.
A lot of other people are atheists.
There are some other religious cults in Japan including Soka Gakkai, Kofuku no Kagaku, and so on.
Of all, Soka Gakkai is the biggest and it has one political party called Koumei party.
It could be concluded that a lot of Japanese people don’t have creed in one particular religion but believe the concept of God itself.
