The Empire of Uzushio is a gargantuan, socially progressive nation, ruled by Uzumaki Senju Raiha with a fair hand, and remarkable for its multi-spousal wedding ceremonies, smutty television, and absence of drug laws. The hard-nosed, democratic population of 27.672 billion Uzushioans hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The large, liberal, outspoken government prioritizes Education, with Environment, Healthcare, and Law & Order also on the agenda, while Spirituality and Defense aren't funded at all. It meets to discuss matters of state in the capital city of Uzushiogakure. The average income tax rate is 90.2%, and even higher for the wealthy.

The frighteningly efficient Uzushioan economy, worth a remarkable 5,351 trillion Uzus a year, is quite specialized and led by the Tourism industry, with significant contributions from Information Technology, Book Publishing, and Beef-Based Agriculture. State-owned companies are common. Average income is an impressive 193,386 Uzus, and evenly distributed, with the richest citizens earning only 2.5 times as much as the poorest.

Posters on 'Uzushioan Values' advise against being proud of Uzushio, the nation is devoted to world peas, hundreds of subterranean tunnels are being built as part of "Project Morlock", and the government has pinkie-promised never to use its veto power except in an emergency. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Uzushio's national animal is the Fox, which frolics freely in the nation's many lush forests, and its national religion is None.

Uzushio is ranked 5,109^th in the world and 233^rd in Osiris for Most Cultured, scoring 166 on the Snufflebottom-Wiggendum Pentatonic Scale.
