Wano Country One Piece ki sab se important locations mein se ek hai. Ye ek isolated island hai jo New World mein hai aur yahan samurai ki culture aur traditions hain. Wano ka design feudal Japan se inspired hai. Yahan Kaido — duniya ka sab se taqatwar creature — ne apni saltanat qayam kar rakhi thi. Wano ki khaas baat yahan ki Poneglyphs hain jo ancient history ke raaz rakhti hain. Road Poneglyph bhi yahin hai jo Laugh Tale tak pohanchne ke liye zaroori hai. Kozuki clan jo Wano ke asli rulers the, unke paas Poneglyphs padhne ka raaz tha. Wano arc One Piece ka ab tak ka sab se lamba aur epic arc raha — Luffy ne yahan Gear 5 activate kiya aur apni asli Devil Fruit power — Hito Hito no Mi Model: Nika — discover ki. Luffy, Law, Kid, Zoro, Sanji, Killer aur doosre Supernovas ne milkar Kaido aur Big Mom ke alliance ko takkar di. Wano ke aakhri battle mein Luffy ne Bajrang Gun attack se Kaido ko defeat kiya. Wano ki azaadi One Piece ki kahani ka ek turning point hai.
