The Kingdom of Mount Hourai is a titanic, genial nation, ruled by Hourai no Kotohime with an even hand, and remarkable for its ubiquitous missile silos, aversion to nipples, and frequent executions. The compassionate, democratic, cheerful, devout population of 12.68 billion Hourainese 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 Education, Administration, and Law & Order. It meets to discuss matters of state in the capital city of Omoikane. The average income tax rate is 72.2%, and even higher for the wealthy.

The frighteningly efficient Hourainese economy, worth a remarkable 1,909 trillion Udonge Tamas a year, is fairly diversified and led by the Tourism industry, with significant contributions from Information Technology, Book Publishing, and Retail. State-owned companies are common. Average income is an impressive 150,625 Udonge Tamas, and evenly distributed, with the richest citizens earning only 2.7 times as much as the poorest.

Raccoons are plump and satiated, moles make up an incredible part of the upper crust, domestic fishermen fly the Hourainese flag out of fear of being blown up, and inheritance tax has recently been abolished. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mount Hourai's national animal is the Inaba White Hare, which is also the nation's favorite main course, and its national religion is Kaguyaism.

Mount Hourai is ranked 314,262^nd in the world and 40^th in Eientei Gensokyo for Largest Welfare Programs, scoring -7.07 on the Safety Net Mesh Density Rating.
