Many people live on small islands. 
Long ago, they lived on the islands alone. They built a kingdom to trade with others. 
Later, things changed for the people. New leaders took over their land. This made it hard to keep their old ways.
Today, many Ryukyuans live in Japan. They still keep their own culture. It is a very special way of life.
Ryukyuans are a group of people from the Ryukyu Islands. 
Long ago, the people lived on the islands alone. In the 14th century, they made the Ryukyu Kingdom. 
During the Meiji era, the government tried to change Ryukyuan ways. They tried to make people act more like the Yamato people. After World War II, the United States stayed on the islands. This lasted from 1945 until 1972. Today, many Ryukyuans still care deeply about their own culture. They also have many views on the military bases in Okinawa.
The Ryukyuans are a group of people from the Ryukyu Islands. 
Ryukyuan culture has many special and distinct parts. Their traditional religion is indigenous to the islands. They also have a unique way of cooking food. For a long time, rice was not a main part of their diet. It was only introduced to the islands around the 12th century. Some parts of their culture even show matriarchal elements. This means women held important roles in the community. Their history is tied deeply to the sea and trade.
Long ago, the people lived on these islands in isolation. In the 14th century, three different groups merged together. This created the Ryukyu Kingdom, which lasted from 1429 to 1872. 
Things changed greatly during the Meiji era of Japan. The Empire of Japan took control of the islands. First, the kingdom became the Ryukyu Domain in 1872. In 1879, the domain was abolished and became Okinawa Prefecture. 

Scientists study the Ryukyuans to learn about the past. Genetic studies show they are a distinct group of people. They share a lot of ancestry with the Jōmon people. These were prehistoric hunter-gatherers who lived long ago. 
The Ryukyuans are an East Asian ethnic group native to the Ryukyu Islands. 
Ryukyuan culture is distinct and includes several unique characteristics. Their indigenous religion and specific cuisine set them apart from mainland neighbors. For example, rice was not a staple until the 12th century. Some social structures also show matriarchal elements, where women hold significant roles. The people often use specific names for themselves to mark this identity. They may call themselves Uchinaanchu or Shimanchu. The term "Okinawa" is a Japanese version of the indigenous name "Uchinaa." 
History shows that the Ryukyuans lived in isolation for many centuries. In the 14th century, three separate political groups merged together. This merger created the Ryukyu Kingdom, which ruled from 1429 to 1872. The kingdom was famous for maritime trade and tributary relations. They began these trade connections with Ming China in 1372. In 1609, the Satsuma Domain from Kyushu invaded the kingdom. The kingdom then held a unique dual status. It acted as a subordinate to both China and Japan. This was possible because Tokugawa Japan could not trade directly with China.
The political status of the islands changed during the Meiji era. The Empire of Japan began the process of political annexation. In 1872, the kingdom became the Ryukyu Domain. By 1879, the domain was abolished and turned into Okinawa Prefecture. 
Following World War II, the islands experienced a new period of change. The United States occupied the Ryukyu Islands from 1945 to 1950. This occupation continued again from 1950 until 1972. Since the end of World War II, many Ryukyuans have felt resentment. This is often linked to the large number of U.S. military facilities in Okinawa. In 2006, a United Nations rapporteur noted levels of discrimination and xenophobia. Much of this discrimination is tied to local opposition to these military installations. 
Scientists use genetic studies to understand Ryukyuan origins. Research shows they are a distinct genome-wide cluster within the Japanese people. They share many alleles with southern Jōmon hunter-gatherers. The Jōmon were prehistoric people who lived long ago. Estimates of Jōmon ancestry in Ryukyuans range from 26.1% to 36%. This differs from the Yamato Japanese, who have more mainland Asian ancestry. This follows the dual-structure model proposed by Hanihara in 1991. 
Detailed DNA analysis helps trace ancient human migrations. Researchers look at mitochondrial DNA and Y chromosome markers. For example, the M7a haplogroup is often linked to the Jōmon genotype. This may have come from Southeast Asia during the Last Glacial Maximum. Studies of skeletal remains from the Neolithic Shell midden period show genetic continuity. Ryukyuans also show high genetic affinity with the Ainu people. Both groups share higher levels of Jōmon ancestry than the average mainland Japanese. 
Physical studies provide even more clues about the past. Anthropological studies look at dental diversity and skull shapes. Some studies show that Ryukyuans were historically shorter than mainland Japanese. They often had broader faces and different nasal structures. These traits reflect long-term isolation and genetic drift. Some researchers believe these features are well-preserved phenotypes from the Jōmon era. This helps scientists understand how different populations moved and settled across East Asia.
