The MC Mid Bro of Jiro is a colossal, genial nation, ruled by Jiro Yamada with a fair hand, and notable for its free-roaming dinosaurs, state-planned economy, and irreverence towards religion. The compassionate, democratic population of 3.568 billion Jiroes love a good election, and the government gives them plenty of them. Universities tend to be full of students debating the merits of various civil and political rights, while businesses are tightly regulated and the wealthy viewed with suspicion.

The large, socially-minded government juggles the competing demands of Education, Administration, and Healthcare. It meets to discuss matters of state in the capital city of Ikebukuro. The average income tax rate is 58.5%, and even higher for the wealthy.

The large but underdeveloped Jironese economy, worth 124 trillion BALLS a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Tourism industry, with major contributions from Book Publishing, Soda Sales, and Uranium Mining. Average income is 35,003 BALLS, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Praying before a battle is a court-martial offence, road signs are getting harder to read under layers of knitted woolen cardigans, earthquake sirens are a leading cause of hearing loss, and advertisements for jobs in the sciences run in fashion magazines. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Jiro's national animal is the Nii-chan, which frolics freely in the nation's many lush forests, and its national religion is steelo.

Jiro is ranked 326,596^th in the world and 17^th in OrangeJuice for Largest Manufacturing Sector, scoring zero on the Gooback-Jerbs Productivity Index.
