Ryukyu Kingdomball was a countryball in what is now the modern day Japanese prefectureball of Okinawaball. He lasted from 1429 to 1879 and was close to Tokugawaball (Japanball then). Now he's only a separatist country ball. Many importants castles of UNESCO heritage are still stored on Okinawaball. Ryukyu Kingdomball should be noted for his fancy royalty hats.
