The Orthodox Shintoist Empire of Himekaidou is a gargantuan, cultured nation, ruled by Queen Hatate Himekaidou with an iron fist, and remarkable for its rampant corporate plagiarism, frequent executions, and stringent health and safety legislation. The hard-nosed, cynical, humorless, devout population of 20.95 billion Himekaidouans 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 enormous, corrupt, well-organized government juggles the competing demands of Defense, Law & Order, and Education. It meets to discuss matters of state in the capital city of Hakodate. The average income tax rate is 99.0%.

The frighteningly efficient Himekaidouan economy, worth a remarkable 3,939 trillion Royal Yen a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a slick, highly efficient, quite specialized black market in Information Technology, Arms Manufacturing, Book Publishing, and Retail. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 188,028 Royal Yen, and evenly distributed, with the richest citizens earning only 2.8 times as much as the poorest.

Billions of Royal Yen are being blown on orbital weapons development, even doll houses and dog kennels have to be able to withstand rigorous earthquake testing, 'Police Academy 36' and 'Sharknados On A Plane' are vying for top spot at the box-office, and in a fit of passion Queen Hatate Himekaidou has shredded thirty years' worth of petitions. Crime is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Himekaidou's national animal is the Raven, which is also the nation's favorite main course, and its national religion is Orthodox Shinto.

Himekaidou is ranked 200,776^th in the world and 20^th in Gensokyo for Safest, scoring 41.03 on the Bubble-Rapp Safety Rating.
