The Commonwealth of Edogashima is a large, environmentally stunning nation, notable for its compulsory vegetarianism, devotion to social welfare, and stringent health and safety legislation. The compassionate, democratic, devout population of 180 million Edogashimen are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The medium-sized, liberal, socially-minded government juggles the competing demands of Education, Welfare, and Administration. The average income tax rate is 49.6%, but much higher for the wealthy.

The sizeable but stagnant Edogashiman economy, worth 4.45 trillion Edoshis a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is fairly diversified, is led by the Book Publishing industry, with major contributions from Information Technology, Tourism, and Uranium Mining. Average income is 24,749 Edoshis, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Religion is strictly forbidden within school grounds, would-be emigrants are told "abandon all hope all ye who would exit here", spies caught red-handed are served cocktails on their first-class flights home, and there is a heavy social stigma attached to e-cigarettes. Crime is totally unknown. Edogashima's national animal is the Fenix, which frolics freely in the nation's many lush forests.

Edogashima is ranked 196,415^th in the world and 217^th in Umamusume Pretty Derby for Largest Cheese Export Sector, scoring 949.53 on the Mozzarella Productivity Index.
