Okinawan culture is the result of hundreds of years of contacts and influences from East-Asian countries that have mixed here with the indigenous beliefs and customs evolving into traditions that are in practice to this day. Performing arts were often born in the royal court and later absorbed into everyday life. Need for self-preservation resulted in karate and its philosophy, while indigenous religious beliefs spawned such customs as Eisa. Most recently, as a result of American occupation, rock music invaded the islands. All this combined has resulted in the most genuine Okinawan tradition of all, chanpuru (mix).
