Japanese poems and literature are filled with references to the clear, cool, waters of the country. Water is culturally significant in Japan, viewed as representing calm, clarity and especially purity. The sea (海, umi) is revered in Japanese culture and in Shinto rites, as both giver of life, symbol of openness, and a source of danger and isolation. Japanese kami like Ryujin, the dragon god of the sea, representing strength and power, is revered as a benefactor of Japan for the sea's life giving nature. Ebisu, the god of the sea and its fish, is considered one of the seven gods of good fortune, and is revered by both fisherman and businessmen alike.
