A cultural catalyst

Shinto has been called "the religion of Japanese-ness", and the customs and values of Shinto are inseperable from those of Japanese culture prior to the influx of Chinese religious ideas that occured in the mid 6th century. Many famously Japanese practices have origins either directly or indirectly rooted in Shinto. For example, it is clear that the Shinto ideal of harmony with nature underlies such typically Japanese arts as flower-arranging (ikebana) and traditional Japanese architecture and garden design. A more explicit link to Shinto is seen in sumo wrestling, where, even in the modern version of the sport, many Shinto-inspired ceremonies must be performed before a bout, such as purifying the wrestling arena by sprinkling it with salt. It is still very common for Japanese to say, "Itadakimasu" (I humbly partake) before eating, and the Japanese emphasis on proper greetings can be seen as a continuation of the ancient Shinto belief in kotodama (words with a magical effect on the world).

Many Japanese cultural customs, like using wooden chopsticks and removing shoes before entering a building, have their origin in Shinto beliefs and practices. Also, a number of other Japanese religions, including Tenrikyo, have originated from or been influenced by Shinto.
