The Queendom of Datenchi Yua is a colossal, safe nation, notable for its burgeoning mouse population. The hard-working, democratic, devout population of 4.39 billion Datenchi Yuan hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The relatively small, outspoken government juggles the competing demands of Education, Welfare, and Healthcare. The average income tax rate is 15.2%.

The Datenchi Yuan economy, worth 196 trillion yen a year, is fairly diversified and led by the Basket Weaving industry, with major contributions from Book Publishing, Automobile Manufacturing, and Door-to-door Insurance Sales. Average income is 44,679 yen, and evenly distributed, with the richest citizens earning only 3.6 times as much as the poorest.

The government prides itself on being smug and condescending to idiots, cheese lovers have a case of the bleus, citizens select which government department gets their income tax yen each year, and euthanasia is illegal. Crime is well under control. Datenchi Yua's national animal is the mouse, which can occasionally be seen sifting through garbage in the nation's cities.

Datenchi Yua is ranked 257,077^th in the world and 4,028^th in Ambition for Most Eco-Friendly Governments, scoring zero on the Dolphin Recycling Awareness Index.
