What role does religion play in Japanese society? Almost none.
"What role does religion play in Japanese society? Almost none."
Based on what evidence? I see you didn't answer my question about actually having been there, so I assume you haven't. And, yes, I have.
As I said, you are clueless about this. They are not atheists and they would NEVER claim to be atheists. They do not believe in a deity like most people in the Judeo-Christian populations do but they are not atheists like you claim, either.
