Okay kiddo, let me explain this to you. Ryukyuans are people who come from the Ryukyu Islands in Japan. Some of these Ryukyuans moved to Brazil a long time ago, and they brought their culture and traditions with them.
You know how sometimes you might move to a new place and still keep your family traditions and favorite foods? That's kind of what the Ryukyuans did when they moved to Brazil. They still celebrate their festivals, wear their traditional clothes, and eat their special foods.
But even though they kept some of their own traditions, the Ryukyuans in Brazil also learned to adapt and mix with the Brazilian culture. They might speak Portuguese and make new friends, but they still remember where they come from and their own unique heritage.
It's pretty cool to see how different cultures can come together and learn from each other. Who knows, maybe someday you'll get to meet some Ryukyuans in Brazil and learn more about their culture!
