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, this was the land Ryuuma walked around on, 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. Portgas D. Ace has also been known to be there, where he receives a bamboo hat which he gives to Oars Jr., solidifying their friendship.

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