How many Christian churches are there in Japan?

Answer 1

There are an estimated 70 million Christians in China. The majority of them attend what are known as house churches; churches that are not recognized by the Chinese government, and that meet in houses. So it is very hard to say how many churches there are in China, since we would have to know how many of these house churches there are, and they meet in secret, so we can't possibly know just how many there are.

Answer 2

According to the Japanese Church Information Service, in 2009 there were 7,879 churches with a membership of 548,643 and an average weekly attendance of 279,932.
