The Empire of MasterKohga is a colossal, safe nation, ruled by Master Kohga with an even hand, and remarkable for its compulsory military service and ubiquitous missile silos. The quiet, industrious population of 3.912 billion Yiga Footsoldiers are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The medium-sized government juggles the competing demands of Defense, Law & Order, and Welfare. It meets to discuss matters of state in the capital city of Yiga Clan Hideout. The average income tax rate is 41.3%, but much higher for the wealthy.

The large but underdeveloped MasterKohgan economy, worth 145 trillion Mighty Bananas a year, is fairly diversified and led by the Door-to-door Insurance Sales industry, with major contributions from Trout Farming, Woodchip Exports, and Automobile Manufacturing. State-owned companies are common. Average income is 37,275 Mighty Bananas, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Master Kohga has just been declared ruler of MasterKohga in an international press conference, the military is recruiting war criminals to join its weapons research teams, citizens who leave the country are officially classed as traitors, and viewers get headaches from trying to read the screen full of small print warnings that precede most TV shows. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. MasterKohga's national animal is the Bokoblin.

MasterKohga is ranked 158,125^th in the world and 11^th in Emu Timeline Oceania for Largest Populations, with 3.91 billion capita.
