Location from One Piece by Eiichiro Oda
An isolated samurai nation sealed off from the world for centuries, occupied by Kaido and the Beast Pirates for twenty years. Cherry blossoms, katanas, and an oppressed people waiting for the dawn.
Wano is the story of a country betrayed. Twenty years ago, Kozuki Oden was executed by Kaido and the shogun Orochi in a conspiracy that overthrew the rightful rulers and turned the nation into a weapons factory. The samurai were disarmed. The people were starved. The Flower Capital's citizens were kept fat and ignorant while everyone else suffered. Oden's retainers — the Nine Red Scabbards — were scattered across time itself by Toki's Devil Fruit, arriving twenty years in the future to fulfill their lord's dying wish. The Straw Hats' alliance with the samurai and mink tribes led to the Raid on Onigashima, where Luffy finally defeated Kaido. Wano carries deep connections to the Void Century: the Kozuki clan created the Poneglyphs, and Wano's borders were closed to protect some ancient secret that has yet to be fully revealed.
A country of staggering natural beauty modeled on feudal Japan. Cherry blossom trees line river banks. Torii gates mark mountain paths. Samurai castles rise above terraced rice paddies. But look closer: the Flower Capital gleams with wealth and festival lights while the rest of the country starves. Factories pump poison into rivers. Kuri and the other outlying regions are wastelands where the people eat poisoned fish and drink contaminated water because Kaido's weapons factories have destroyed everything else. Wano's isolation is enforced by massive waterfalls that flow upward at its borders — ships must ride these impossible currents to enter.
