Namakura Island

Namakura Island is an island in the Grand Line where the Land of Poverty resides, Harahettania (ハラヘッターニャ). "Hara hetta" means "I'm hungry" in Japanese.

History
The place is completely ravaged and the people there live in destitution. The turmoil of the country can be largely attributed to the Longarm Tribe. Because of this, the people decided to rely on a demon summoning ritual to solve their problems. It was during the very moment they were doing this ritual that Brook landed here after being sent flying from the Sabaody Archipelago by Kuma's Devil Fruit powers. Having landed precisely during the ritual, the people believe that they've successfully summoned Satan, the "King of Demons".
