Okinawa, Japan used to be called Ryukyu Island, facing Japan across the sea. However, compared with Japan, its history and culture are far behind. Humans appeared on Ryukyu Island as early as 32,000 years ago. In a cave near Naha Port, human remains of 18000 years ago were found. According to archaeologists, they came to Okinawa through Taiwan Province Province, and their culture even spread to South Kyushu. In addition, Japan's rope culture also influenced the Okinawa Islands, but the influence was very weak at that time.
