The most unusual cultural custom

Though Japan is not monotheism culture, there are many countries that emphasize one religion. That makes big difference between Japan and others. The religion specifies atmosphere of country that believes in it and the life style of people who believe in it. For example,when I visited to some companies in Malaysia, I knew that there was time to go to chapel while even working. It is usual thing in the country that believes in Islam. It's interesting for me.
