Onigashima
Onigashima is a fictional island in the manga and anime series One Piece by Eiichiro Oda. It serves as a central stronghold and battleground within the Wano Country arc, notable for hosting large-scale conflicts involving major factions such as the Straw Hat Pirates, Beasts Pirates, and the Nine Red Scabbards. Its strategic and narrative importance stems from its association with Yonko-level antagonists and the climax of multiple plotlines in the series.
Onigashima is presented as a mobile and fortified island used as a base by the Beasts Pirates and allied forces, most prominently the Yonko Kaido. During the Wano arc, Onigashima becomes the focal point of an alliance formed by the Straw Hat Pirates, Minks, Heart Pirates, Killer and the Kozuki loyalists aiming to overthrow the shogunate puppet regime led by Kurozumi Orochi and Kaido's occupation. The island's name echoes Japanese folklore Onigashima legend but is reimagined in Oda's world as a floating/fortified fortress with cultural and military roles.
Onigashima is located off the coast of Wano Country in the New World sector of the Grand Line. Its physical form during the Wano arc is an artificial island resembling a large fortress with castle-like structures, docks, and an inner citadel where Kaido and his commanders reside. The island's environment includes volcanic features and heavy fortifications consistent with Kaido's military infrastructure, and its approach is protected by fleets of Beasts Pirates ships and flying transports used by allies like Big Mom during the Raid on Onigashima.
Onigashima's population at the time of the raid is a mix of Kaido's subordinate factions and allied pirates. Major groups based on or present on the island include: - The Beasts Pirates, commanded by Kaido and featuring top officers such as the Disasters/All-Stars (King, Queen, Jack). - Allied Yonko forces, including a contingent led by Big Mom who temporarily aligns with Kaido. - Prisoners and forced laborers, including captives from Wano and prominent characters such as Oden (in flashback) and others shown in the arc. - The attacking coalition: Straw Hat Pirates, Mink Tribe members (including Inuarashi and Nekomamushi), Heart Pirates under Trafalgar Law, Eustass Kid allies, and the Nine Red Scabbards led by Kozuki Toki's retainers.
Onigashima functions as the culminating battlefield of the Wano Country arc. The island houses Kaido's forces and is the site of political machinations by Kurozumi conspirators who control the bakufu through Kurozumi Orochi. The Raid on Onigashima is orchestrated to dismantle Kaido's alliance with Orochi and to restore the Kozuki clan's rule, aiming to open Wano's borders and reveal the location of ancient secrets such as the Poneglyphs. Onigashima's fall is pivotal for reshaping the balance of power among the Four Emperors and impacting the broader World Government order.
Onigashima hosts several major set-piece events and duels that drive the arc's climax: - The initial incursion known as the "Raid on Onigashima", a multi-phase assault coordinated by the alliance featuring infiltration, diversionary tactics, and full-scale frontal attacks. - High-profile battles between Yonko-level fighters, including confrontations: Monkey D. Luffy vs. Kaido, and clashes involving Big Mom against other heavyweights. - Duels involving the All-Stars: King, Queen, and Jack engage members of the alliance such as Roronoa Zoro, Sanji, and the Nine Red Scabbards. - Sub-battles on Onigashima's decks, courtrooms, and inner keep where characters like Killer, Franky, and Usopp undertake missions that influence the raid's outcome. - Flashback sequences set on Onigashima or involving its leadership reveal backstory tied to Kozuki Oden's invasion of Kaido's territory and the subsequent downfall of Wano, with repercussions for the Poneglyph quest and Road Poneglyphs.
Onigashima's name and aesthetic draw heavily from Japanese myth, notably the tale of the oni island where ogres dwell, which provides symbolic resonance within Wano, a nation inspired by Edo period Japan. In-universe, the island embodies the oppressive rule of an occupying force and serves as a stage for themes of revenge, inheritance, and liberation central to the Kozuki storyline. Its defeat is framed as a restoration of Wano's sovereignty and continuity with Kozuki Oden's legacy, while also affecting global narratives like the pursuit of the One Piece and the revelation of ancient secrets.
