The highest estimates for the amount of Buddhists and Shintoists in Japan is 84-96%, representing a large number of believers in a syncretism of both religions.[6][95] However, these estimates are based on people with an association with a temple, rather than the number of people truly following the religion.[96] Professor Robert Kisala (Nanzan University) suggests that only 30 percent of the population identify themselves as belonging to a religion.[96]
Taoism and Confucianism from China have also influenced Japanese beliefs and customs. Religion in Japan tends to be syncretic in nature, and this results in a variety of practices, such as parents and children celebrating Shinto rituals, students praying before exams, couples holding a wedding at a Christian church and funerals being held at Buddhist temples. A minority (2,595,397, or 2.04%) profess to Christianity.[97] In addition, since the mid-19th century, numerous religious sects (Shinshūkyō) have emerged in Japan, such as Tenrikyo and Aum Shinrikyo (or Aleph).
