Okinawa was originally called Ryukyu, which was a Chinese state during the Ming and Qing Dynasties. Okinawa was the name after the Japanese seized it, and Ryukyu was the name the Chinese took for the islands during the Ming Dynasty. Since ancient times, China has maintained close cultural exchanges and overseas trade with North Korea and Southeast Asian countries, so the customs and culture of the Japanese Ministry of Culture have been very different from Japan's architectural style. Okinawa is a warm and pleasant climate, subtropical marine climate area. The economy is most developed in tourism. Because it is located on the continental shelf of the Pacific Ocean, the nearby waters are rich in fish, and the fishery is a profession that Okinawa people are engaged in.
