Wano Country

The Wano Country is a nation in the New World where Ryuuma is from. Since Monsters is connected with the main One Piece storyline, it may be possible that the land Ryuuma walked around on is Wano itself but it's still unknown what kind of features besides a town and normal trees Wano may have. First mentioned by Hogback, Ryuuma had slayed a Dragon there.

The name is a pun, as "Wa no Kuni" is used as a name for Japan.
