The Underworld of Chamazak is a massive, genial nation, ruled by Kaenbyou Rin with an iron fist, and notable for its barren, inhospitable landscape, state-planned economy, and punitive income tax rates. The cynical, devout population of 1.177 billion Gensokyoans 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 government juggles the competing demands of Defense, Spirituality, and Welfare. It meets to discuss matters of state in the capital city of Chireiden. The average income tax rate is 58.3%, and even higher for the wealthy.

The local economy, worth 59.5 trillion mons a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is fairly diversified, is led by the Pizza Delivery industry, with significant contributions from Woodchip Exports, Door-to-door Insurance Sales, and Information Technology. Average income is 50,517 mons, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

Reporters who negatively comment on politicians' haircuts are cut from the news, a well-funded social safety net protects the unfortunate, local husbands are dead good at fathering kids, and the government has declined to declare any particular religion as its 'official' one. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Chamazak's national animal is the Haimushi, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Shintoism.

Chamazak is ranked 131,941^st in the world and 44^th in Eientei Gensokyo for Largest Gambling Industry, scoring 784.97 on the Kelly Criterion Productivity Index.
