Shinto is Japan's ancient polytheistic religion that expresses love and respect for nature. Shinto has no identifiable founder or holy texts. Kami refer to Shinto deities or spirits that can be forces of nature, important people, or natural objects. Shrines are built dedicated to specific kami, and ceremonies include cleansing rituals, offerings, prayers, and dances to ask the kami for blessings. Physical cleanliness, respect for traditions and family, and love of nature are core tenets of Shinto.
