The Fiefdom of Yui Yagi is a very large, pleasant nation, notable for its burgeoning bird population. The hard-working population of 140 million Yui Yagians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized government juggles the competing demands of Defense, Law & Order, and Healthcare. The average income tax rate is 19.0%.

The Yui Yagian economy, worth 6.30 trillion ryous a year, is fairly diversified and led by the Tourism industry, with major contributions from Furniture Restoration, Pizza Delivery, and Basket Weaving. Average income is 45,023 ryous, and evenly distributed, with the richest citizens earning only 3.4 times as much as the poorest.

TV shows must meet strict ethnicity quotas, Harry Potter books are banned, organ donation is compulsory, and warning signs caution Yui Yagians where they may fall off 'the edge of the world'. Crime is relatively low, thanks to a capable police force and progressive social policies in education and welfare. Yui Yagi's national animal is the bird.

Yui Yagi is ranked 252,281^st in the world and 1,904^th in Remembrance for Largest Populations, with 140 million capita.
