The Supreme Empire of Johill is a titanic, efficient nation, ruled by HIM Emperor Ryōkai with an iron fist, and remarkable for its compulsory military service, frequent executions, and prohibition of alcohol. The hard-nosed, cynical, humorless, devout population of 10.721 billion Imperial Subjects are ruled without fear or favor by a psychotic dictator, who outlaws just about everything and refers to the populace as "my little playthings."

The medium-sized, corrupt, moralistic, socially-minded, well-organized government juggles the competing demands of Law & Order, Defense, and Education. It meets to discuss matters of state in the capital city of Imperial Sōshaku. The average income tax rate is 95.3%.

The frighteningly efficient Johillian economy, worth a remarkable 2,935 trillion Johillian Dollars a year, is fairly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Tourism, and Retail. Black market activity is rampant. State-owned companies are common. Average income is an amazing 273,829 Johillian Dollars, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Starving citizens are offered nuclear pasta, the JBI Channel Tunnel project is plagued by delays, Johillian tourists are banned from many nations due to their tendency to randomly explode, and Renaissance frescos are being chiselled off public walls. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Johill's national animal is the Red Emperor Butterfly, which is also the nation's favorite main course, and its national religion is Tendō.

Johill is ranked 118,695^th in the world and 56^th in Commonwealth of Sovereign States for Largest Trout Fishing Sector, scoring 2,352.73 on the Nemo Depletion Efficiency Index.
