The Constitutional Empire of Nakayo is a gargantuan, safe nation, ruled by Yōmuin with an even hand, and notable for its compulsory vegetarianism, feral children, and devotion to social welfare. The compassionate population of 10.248 billion Nakayans enjoy extensive civil rights and enjoy a level of social equality free from the usual accompanying government corruption.

The enormous, socially-minded government juggles the competing demands of Education, Environment, and Healthcare. It meets to discuss matters of state in the capital city of Saikonotoshi. The average income tax rate is 96.1%.

The frighteningly efficient Nakayan economy, worth a remarkable 1,488 trillion Kōkins a year, is highly specialized and mostly made up of the Information Technology industry, with significant contributions from Book Publishing and Tourism. State-owned companies are common. Average income is an impressive 145,289 Kōkins, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Government bureaucrats review designs for birdhouses to ensure they do not block the views of neighbors, unemployed accountants keep double-entry ledgers of their benefit claims, the government is making attempts at curtailing the flood of spam emails with little progress, and scientific journals publish third-graders' school essays. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Nakayo's national animal is the Cyan-crested Heron, which soars majestically through the nation's famously clear skies.

Nakayo is ranked 11,338^th in the world and 261^st in the South Pacific for Most Scientifically Advanced, scoring 382.87 on the Kurzweil Singularity Index.
