Tetsuya

Tetsuya (哲也), formally the Tetsuya Special Administrative District (哲也都) and commonly referred to as The District, is the capital of the Federal Kingdom of Teiko. The signing of the Residence Act on April 23, 1987, approved the creation of a capital district located along the Kuroko River on the southern side of the country's largest city, Kaijo Metropolis. The Constitution of Teiko provided for a district under the exclusive jurisdiction of the Central-46 and the District is therefore not a part of any local or prefectural administrative division. The same with Kaijo and Rakuzan, it is one of the three direct government controlled districts in the country.

The Kamizaki Prefecture has donated land to the federal government to form the district which included the pre-existing towns of Konoha, Kumoga, Kiriga, Sunaga and Iwaga. Named in honor of Tetsuya Kuroko. the Tetsuya Special Administrative District was founded in 1987 to serve as the new national capital replacing Kaijo. Since 1990, massive internal migration have increased the district's population to more 650,000 making it one of the largest cities in Teiko. Tetsuya is part of Kaisenmai, the largest urban agglomeration in Teiko spanning south from Rakuzan to the Beika in the northeast.

The seat of the Imperial Family of Teiko and the centers of all three branches of the federal government of Teiko are in the District, including the Teiko National Council colloquially called as Central-46, Premier, and Supreme Court of Teiko. Tetsuya is home to many national monuments and museums, which are primarily situated on or around the City Square and Central Tetsuya. The city hosts 169 foreign embassies and consulates as well as regional headquarters of many international organizations, trade unions, non-profit organizations, lobbying groups, and professional associations.

Tetsuya was completely under the control of the Central-46 since 1987 but in 2009, the District was given local sovereignty through an election of a district governor and legislature. However, the Central-46 maintains supreme authority over the city and may overturn local laws. Tetsuya residents elects three single constituency district representatives in the council representing the three non-administrative wards of the city and ten district representative through party-list proportional representation.
