Corsica is an island in the Mediterranean Sea and one of the 18 regions of France. It is located southeast of the French mainland and west of the Italian Peninsula, with the nearest land mass being the Italian island of Sardinia to the immediate south. A single chain of mountains makes up two-thirds of the island.
While being part of Metropolitan France, Corsica is also designated as a territorial collectivity (collectivité territoriale) by law. As a territorial collectivity, Corsica enjoys a greater degree of autonomy than other French regions; for example, the Corsican Assembly is able to exercise limited executive powers.
From the Banana Fish's universe, Corsica is the place where The Corsican Mafia (lead by Dino Golzine) live until the formed the organization.
