Death Country

Death Country is one of the provinces of JAPAN. It has the largest Hole of Hell in JAPAN, one so big the Yin Yang Masters of the Hojo House are incapable of closing it, and instead constructed a giant gate locking Death Country away from the rest of JAPAN. It has become a land of Oni, former nobles, criminals, the cursed, the mutated, and outcasts. Life expectancy in this land of the forsaken is less than one year.

On the other side of the giant gate lies the province of Mid Earth.

Trivia

 * Death Country is a pun on the island of Shikoku of real-world Japan, changing the kanji of "shi" from "四" (meaning "four") to "死" (meaning "death")
