Japan is a super society. A friend who travels to Japan often for work, told me they are the most genuinely considerate people you can imagine. I worry about the future of the US, but I don't worry about Japan.
I'm not sure how you got the statistic that 63% believe in God in Sweden. Sweden and Norway are the promised land for atheists. Almost nobody believes in God there. A lot depends on the phrasing of the question in these surveys.
In Sweden we are not many maybe about 9 mill,
Norway 61/2- 7,
Roughly, easy checked.
But in any case it is not so as you say, absolute not.
Here a video from a tv series which was very popular,
they made many of these vidioes,
And this only from the pentecostal side
.
Thing is, most people don,t make a big number of it.
Most of those in these vidioes, I know who they are, some I also know.
It is so when living in a big country with few inhabitants.
Thing is, it is free, each are free to indulge in their beliefs.
Promised land for athiests?
All are welcome.
That is how our society works,
no discrimination.
