The Empire of Koryujin is a huge, orderly nation, renowned for its frequent executions, public floggings, and ubiquitous missile silos. The compassionate, hard-working, cynical population of 716 million Koryujins are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, well-organized government juggles the competing demands of Industry, Education, and Healthcare. It meets to discuss matters of state in the capital city of Ryukyo. The average income tax rate is 38.1%.

The frighteningly efficient Koryujinian economy, worth 84.1 trillion Koryu Crowns a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Beef-Based Agriculture, Book Publishing, and Tourism. Average income is an impressive 117,457 Koryu Crowns, and evenly distributed, with the richest citizens earning only 4.8 times as much as the poorest.

New government leaflets tell coeliac children to eat more crisps, viewers get headaches from trying to read the screen full of small print warnings that precede most TV shows, citizens live in superstitious fear of the mysterious glowing clouds that float over Koryujin, and emergency vehicles have built-in nudge bars to give uncooperative drivers a "gentle" push. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Koryujin's national animal is the Black Dragon, which soars majestically through the nation's famously clear skies.

Koryujin is ranked 24,276^th in the world and 27^th in Horizon for Most Scientifically Advanced, scoring 280.27 on the Kurzweil Singularity Index.
