The United Socialist States of Kozerthia is a very large, genial nation, notable for its rampant corporate plagiarism, absence of drug laws, and devotion to social welfare. The compassionate, democratic population of 229 million Kozerthians 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 government juggles the competing demands of Education, Welfare, and Administration. The average income tax rate is 30.7%, but much higher for the wealthy.

The sizeable but inefficient Kozerthian economy, worth 9.63 trillion condoms a year, is led by the Book Publishing industry, with major contributions from Pizza Delivery, Beef-Based Agriculture, and Information Technology. State-owned companies are common. Average income is 42,045 condoms, and distributed extremely evenly, with little difference between the richest and poorest citizens.

A suspicious number of male students have joined the Ladies' Wrestling League, metal detectors have been banned after a bottle cap caused a riot at the beach, the television adaptation of Jennifer Government is the most popular program in the nation, and drug lords often avoid prison time by teaching "chemistry" classes to underprivileged youth. Crime, especially youth-related, is totally unknown. Kozerthia's national animal is the NYN姉貴, which frolics freely in the nation's many lush forests.

Kozerthia is ranked 27,091^st in the world and 3^rd in Eientei Gensokyo for Largest Pizza Delivery Sector, scoring 4,714 on the Pepperoni Propulsion Productivity Index.
