Shinto and Buddhism are two main religions in Japan. When you meet Japanese women, you discover that the majority of them refer to themselves as Buddhists, Shinto, or both. For a bride from Japan, your religion isn't the most important aspect in terms of relationships. Some women may follow religious rituals at ceremonies such as childbirth, weddings, and funerals, but religious differences don't impact family life a lot. When it comes to raising kids and daily life, faith doesn't play an essential role for your future Japanese wife. Be sure you won't face difficulties based on this aspect.
