The Imperial State of Nagakawa is a titanic, efficient nation, ruled by Tomohito with an even hand, and renowned for its anti-smoking policies, free-roaming dinosaurs, and devotion to social welfare. The compassionate, democratic, cheerful population of 16.003 billion Nagakawans are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large government juggles the competing demands of Education, Administration, and Environment. It meets to discuss matters of state in the capital city of Terukuni-no-Mikoto. The average income tax rate is 98.3%.

The frighteningly efficient Nagakawan economy, worth a remarkable 3,610 trillion yen a year, is quite specialized and led by the Information Technology industry, with significant contributions from Tourism and Book Publishing. State-owned companies are common. Average income is an amazing 225,598 yen, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Top gamblers bet against seedy hoopers, a flying elephant and Tomohito share the same nickname, ex-cons are paid to remain law-abidingly dull, and nobody likes bad boys any more. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Nagakawa's national animal is the red-crowned crane, which is also the nation's favorite main course, and its national religion is Shintō.

Nagakawa is ranked 3,015^th in the world and 2^nd in Oatland for Most Scientifically Advanced, scoring 697.77 on the Kurzweil Singularity Index.
