The Empire of Yazawa is a titanic, efficient nation, ruled by Yazawa Nico with an iron fist, and remarkable for its national health service, anti-smoking policies, and infamous sell-swords. The hard-nosed, cynical, cheerful population of 23.806 billion Yazawans are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The large, corrupt, well-organized government juggles the competing demands of Defense, Education, and Industry. It meets to discuss matters of state in the capital city of Ishioka. The income tax rate is 100%.

The frighteningly efficient Yazawan economy, worth a remarkable 9,778 trillion Yen a year, is fairly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Tourism, and Beef-Based Agriculture. State-owned companies are reasonably common. Average income is an amazing 410,775 Yen, and evenly distributed, with the richest citizens earning only 2.3 times as much as the poorest.

Unpopular cops are fired at a moment's notice by the citizens they police, nature magazines featuring stick insects on their covers are sometimes mistaken for fashion magazines, the nation's soldiers sleep four to a bed in order to use space economically, and the only women behind bars are barmaids. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Yazawa's national animal is the Green pheasant, which is also the nation's favorite main course, and its national religion is Shinto.

Yazawa is ranked 289,873^rd in the world and 22^nd in Gensokyo for Most Rebellious Youth, scoring -14 on the Stark-Dean Displacement Index.
