What are the characteristics of Okinawa, Japan?

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. After the Japanese empire was established, the foreign culture of Nara, the aristocratic culture of Heian Dynasty and the samurai culture of the shogunate era began to permeate Okinawa from different channels, and the southeast coastal culture of China and Indonesian culture also indirectly influenced the Okinawa Islands. To some extent, it promoted the formation of Okinawa civilization in the late civilization. Especially since the Ming Dynasty in China, China's politics, economy, culture and art began to influence Okinawa on a large scale. The so-called "crown ship" is a friendly ship between China and Japan on the Silk Road in the South China Sea, which promoted the rapid development of Okinawa civilization in the vast Pacific Ocean.
