The Imperial Japanese carrier of Hiryu is a colossal, socially progressive nation, ruled by Captain Tomeo Kaku with a fair hand, and renowned for its barren, inhospitable landscape and compulsory military service. The hard-working, democratic, devout population of 5.442 billion Hiryuans enjoy a sensible mix of personal and economic freedoms, while the political process is open and the people's right to vote held sacrosanct.

The tiny government juggles the competing demands of Defense, Education, and Welfare. It meets to discuss matters of state in the capital city of HIJMS Hiryū. The average income tax rate is 8.6%.

The strong Hiryuan economy, worth 353 trillion yen a year, is broadly diversified and led by the Book Publishing industry, with major contributions from Uranium Mining, Woodchip Exports, and Beef-Based Agriculture. Average income is 64,935 yen, and evenly distributed, with the richest citizens earning only 4.9 times as much as the poorest.

Shintō has been named as Hiryu's national religion, hospitals fear government fines more than terrorist ransoms, at least 1% of the Ministry of Foreign Affairs budget goes to Captain Tomeo Kaku's wardrobe, and the newest shade developed by Hiryu's dye industry has been dubbed 'Agent Orange'. Crime, especially youth-related, is almost non-existent. Hiryu's national animal is the flying dragon, which teeters on the brink of extinction due to toxic air pollution, and its national religion is Shintō.

Hiryu is ranked 108,190^th in the world and 59^th in Japan for Safest, scoring 79.09 on the Bubble-Rapp Safety Rating.
