Eisa! Nothing is more exciting than this "ghost dancing" parade that takes place in midsummer. The eisa festivities are one of the many Japanese ways to keep family members and friends who have passed away alive in the heart. The drums, the music, and the dancing are a welcome back rite for the loved ones we have lost--and a vigorous "get out of here" warning to whatever evil spirits might be lurking.
Okinawa culture is riding an unprecedented wave of popularity, especially among people who were not born there but visited the island and fell in love with it. It is even popular among those who have never, ever been there.
Culture is said to be the crystallization of human wisdom, knowledge of the secret workings of the heart made visible. That may explain Okinawan culture's power of attraction.
