The Empire of Kaigen is a colossal, cultured nation, ruled by Prime Minister Yakazroto with an iron fist, and notable for its museums and concert halls, unlimited-speed roads, and stringent health and safety legislation. The hard-nosed, hard-working, cynical, humorless population of 3.298 billion Kaigenians 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 government is primarily concerned with Defense, although Industry, Law & Order, and Education are also considered important, while International Aid receives no funds. It meets to discuss matters of state in the capital city of Toroko. The average income tax rate is 78.0%.

The frighteningly efficient Kaigenian economy, worth 642 trillion ₭ Kaigenmarks a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Information Technology, Uranium Mining, and Book Publishing. Black market activity is rampant. Average income is an impressive 194,724 ₭ Kaigenmarks, and evenly distributed, with the richest citizens earning only 3.9 times as much as the poorest.

Failure to pay the thrice-daily homage to the divine Prime Minister Yakazroto is punishable by death, the government seizes all major gold finds, several citizens have complained about scientists abducting their pets for experimentation, and keeping the lights on keeps the lights on for increasing amounts of Kaigenians. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Kaigen's national animal is the shark, which teeters on the brink of extinction due to heavy metals seepage into national waterways, and its national religion is Christianity.

Kaigen is ranked 169,424^th in the world and 7^th in Mappy nerds for Largest Populations, with 3.30 billion capita.
