In Japan, people have certain wishes first, then go to the appropriate god who can answer their requests. So I would say that the religious attitude of most of the Japanese is totally based on calculation. A god is supposed to answer people’s particular requests, and bring them concrete benefits. But make it sure that yo go to the right god. You may not go to the god of pregnancy when you want to pray for good result in the exams!
It is considerably different from our Christian attitude, isn’t it? My Japanese friends have often asked me this question: “What is the benefit of being a Christian?”
