Rangya

Rangya ( IPA: /ˈrɑŋ(g)jə/ ), officially the Kingdom of Rangya (Rangyayo: 琅野王国 rangya wangkok), is an island nation in East Asia. It is located in the East China Sea, with Korea to the north, Japan to the northeast, Japan's Ryukyu Islands (Okinawa) to the southeast, Taiwan to the southwest and Mainland China to the west. The capital and largest city of Rangya is Suiyuchen. Rangya's 2021 population was estimated at about 11.34 million, which against its small size of 5066 km2 makes it one of the most densely populated nations in the world.

Rangya consists of an eponymous main island, home to 98% of the total national population, as well as ten smaller inhabited islands (the most populous of which is home to about 55,000 people) and over 100 uninhabited islets and atolls. It is highly urbanised, with its main cities forming a virtually contiguous single metropolitan area covering all but the mountainous north-central interior of the main island. The public transportation system is extensive and modern, with all urban and suburban centres connected by a commuter train system; there is also a ferry service with regular connections between the eleven inhabited islands, as well as to Okinawa, Taiwan and Mainland China. The kingdom is served by a single international airport located east of Suiyuchen.

Rangya has a warm subtropical climate, and is known for its extensive biodiversity. Rangya's economy is highly developed, with major sectors including manufacturing, finance, information technology, service and hospitality, fishing, tourism and transportation. The kingdom imports most of its food, yet produces much of its own consumer goods; its major exports are commercial and industrial machines, motor vehicles, seafood, appliances and other specialty consumer products. Its workforce is highly educated, with a significant professional expatriate class, and its population enjoys a high standard of living and high median income.
