The Grand Duchy of Fontaia is a titanic, efficient nation, ruled by Grand Duke Fonz IV with an iron fist, and renowned for its closed borders, restrictive gun laws, and suspicion of poets. The hard-nosed, hard-working, cynical, devout population of 13.661 billion Fontaians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, moralistic, well-organized government juggles the competing demands of Defense, Law & Order, and Administration. It meets to discuss matters of state in the capital city of Fantown. The average income tax rate is 46.0%.

The powerhouse Fontaian economy, worth a remarkable 1,198 trillion Fon Marks a year, is broadly diversified and dominated by the Arms Manufacturing industry, with significant contributions from Information Technology, Uranium Mining, and Retail. Black market activity is extensive. Average income is 87,756 Fon Marks, and evenly distributed, with the richest citizens earning only 4.4 times as much as the poorest.

Unpackaged foodstuffs rot on store shelves, the government regularly reassures citizens that there are no monsters under their beds, political shows are fit for purpose, and the line of people waiting for a visa interview in front of foreign embassies is typically a mile long. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Fontaia's national animal is the Mink, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Fontonionism.

Fontaia is ranked 37,994^th in the world and 16^th in Eientei Gensokyo for Largest Populations, with 13.7 billion capita.
