The Ultimate Supreme Leader of OumaKokichi is a gargantuan, efficient nation, ruled by Kokichi Ouma with an iron fist, and renowned for its museums and concert halls, barren, inhospitable landscape, and punitive income tax rates. The hard-nosed, hard-working, cynical, humorless, devout population of 11.359 billion OumaKokichians 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 Industry, Defense, and Law & Order. It meets to discuss matters of state in the capital city of Omagrad. Citizens pay a flat income tax of 67.7%.

The frighteningly efficient OumaKokichian economy, worth a remarkable 3,926 trillion Pantas a year, is broadly diversified and mostly comprised of black market activity, especially in Information Technology, Retail, Uranium Mining, and Woodchip Exports. Average income is an amazing 345,649 Pantas, with the richest citizens earning 9.1 times as much as the poorest.

Political dissidents are cut off from essential services, relations with Dàguó have warmed from frosty to chilly, the government has little issue with allowing its citizens to languish in foreign jails, and chocolate in OumaKokichi has its flavour enhanced by the salty tears of enslaved factory workers. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. OumaKokichi's national animal is the Keeboy, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Haruhiism - SOS Brigade.

OumaKokichi is ranked 5,445^th in the world and 413^th in Lazarus for Highest Disposable Incomes, with 111,644.71 Standard Monetary Units.
