Karafuto (Napoleon's World)

Karafuto is a large island of the Japanese Archipelago in the North Pacific Ocean, separated from Hokkaido by the Sayo Strait and the Mainland Japanese Territories by the Karafuto Strait. Large and cold, Karafuto is the least densely populated of the Home Islands, with about 5 million residents spread out on 72,000 square kilometers. It is closely tied to its neighbor Hokkaido, with a new rail link established in 2017 that goes under the 40-km Sayo Strait and links it with Hokkaido. Oil and gas are the main drivers of Karafuto's economy, providing crucial reserves to the rest of Japan. A large number of Karafuto's population are indigenous Ainu as well as economic migrants from Korea and China.
