Rennya

Rennya (Rennyan: 认野 [ɭe̞ɴːꜜɰa], rennya), formally known as the Republic of Rennya (认野共國 [ɭe̞ɴː.ɰa.kʰɔꜜkʰwɔˀ] , rennya-khokhwo) is an archipelagic country in East Asia. Located in the East China Sea approximately halfway between Mainland China and Japan's Ryukyu Islands, the archipelago constitutes two main islands: Rennyata and Rennyasyo, which at least 87.5% of the country's population inhabit. Virtually all inhabitants of Rennyata speak Rennyan, while most (roughly 90%) Rennyasao's inhabitants speak Raen, although, according to the most recent national census of 2022, at least 75% of Raen speakers inhabiting Rennyasao declare themselves to be "totally fluent" or "mostly fluent" in Rennyan, despite Raen being their primary domestic and working language. Rennyata is located south of Rennyasao, separated by just over half a kilometre of water (approx. 605m, depending on tidal conditions), which is mostly covered in a coral reef; the two main islands are connected by both the A1 road which links the two islands via bridge, and the much busier, faster and more popular R1 expressway, which traverses the gab via an underground tunnel. The country includes an additional 223 much smaller islands and islets, mostly located north-northeast of Rennyasao, of which 85 are permanently inhabited, and which are only accessible by ferries operated by the ARFS (All-Rennya Ferry Service). While most of these smaller islands' economies rely primarily on fishing, several have developed relatively lucrative tourism industries, especially since the start of the 21st century.

The largest cities in Rennya, in order of population, are Suiyuchen, Senphangtsyu, Khyuchen, Ryübaithang, Yohangtsyu, Khyuzü, Thyotsü, Inyo and Chakhya; all are located on the main island of Rennyata, excepting the last two, which are the principal cities of Rennyasyo. Due to the relatively small size of even the largest of the two main islands, Rennyata essentially constitutes a single metropolitan area, with its seven cities forming the cities proper which together form the metropolitan area that covers virtually the whole island. As for Rennyasyo, the southern third of the island is home to the metropolitan area formed by the cities proper of Inyo and Chakhya, but the northern two thirds of the island, which are much more mountainous than the southern third or the Rennyata, constitute a mixture of mountainous forested areas, farmland-covered (mainly coastal or semi-coastal) plains, and smaller cities and towns which generally do not overlap in terms of their suburbs and thus do not form metropolitan areas in the traditional sense of the word.
