Rainbase
Rainbase is a coastal settlement on Fish-Man Island in the world of the manga and anime series One Piece. Situated within the island's northern reaches, Rainbase functions as a local commercial and social hub and figures into events involving several major characters and factions of the New World. Its significance comes from both its role as a waypoint for surface and underwater traffic and as a site reflecting the broader social dynamics between Fish-Men, Merfolk and visiting surface-dwellers.
Rainbase is depicted as a community adapted to the unique environment of Fish-Man Island, combining maritime infrastructure with underwater architecture. The settlement appears during arcs that address cross-species relations, trade routes connecting the Grand Line and the New World, and the aftermath of conflicts such as those involving Punk Hazard and the Sabaody Archipelago repercussions. Rainbase is noted for its marketplaces, docking facilities for submersibles, and proximity to important currents used by Sea Kings and merchant convoys.
Rainbase lies on the plateau encircling the Red Line beneath the ocean, in the general vicinity of the Gyojin Island cluster. The climate at Rainbase is governed by deep-sea conditions; bioluminescent flora, coral terraces, and thermal vents shape local weather-equivalents and currents. The town has access to sheltered inlets and channels used by submarines such as those owned by the Heart Pirates and the Straw Hat Pirates when operating under the sea. Because it is below the Red Line, Rainbase benefits from relatively stable currents but must contend with migrating Sea Kings and the environmental consequences of surface events like Caesar Clown's experiments on Punk Hazard.
The population of Rainbase is primarily composed of Fish-Man and Merfolk, but it also hosts a modest number of surface-dwellers, traders, and pirates. Local culture blends traditional Ryugu Kingdom customs with maritime mercantile practices; festivals often celebrate the bounty of the sea and commemorate historical interactions with surface humans such as the legacy of Fisher Tiger and the rule of King Neptune. Social issues prominent in Rainbase mirror wider One Piece themes: racial tension, discrimination against Fish-Men, and the efforts of reformers like Jinbe to create coexistence. Arts and crafts in Rainbase frequently use coral, pearls, and shellwork, and its cuisine emphasizes seaweed, shellfish, and unique deep-sea species.
Rainbase's economy is based on fishing, coral aquaculture, submersible repair, and localized trade. Market stalls sell goods transported via undersea shipping lanes that connect to the Ryugu Palace markets and to surface ports occasionally. Skilled artisans make jewelry and tools from deep-sea materials sought by surface collectors, while shipwrights service vessels such as the Moby Dick-class craft and private submersibles used by Pirate crews. The settlement also serves as an informal node for intelligence and information exchange among merchants, bounty hunters, and allies of the Revolutionary Army or pirate crews passing through the New World.
Rainbase has appeared or been referenced during arcs that expand the political and cultural landscape of Fish-Man Island within Eiichiro Oda's narrative. It functions narratively as a place of refuge and transit following major incidents: refugees fleeing the hazardous conditions on Punk Hazard or displaced inhabitants from attacks by Whitebeard Pirates-era conflicts could be sheltered there. Rainbase also provides a backdrop for character interactions involving members of the Straw Hat Pirates, allies such as Carrot and Brook when visiting the island, and for diplomacy related to the World Government and the autonomy of the Ryugu Kingdom. Its depiction underscores themes of reconciliation, trade interdependence, and the continuing fallout of scientific and military experiments in the One Piece world.
- Ryugu-trade Quay: A principal docking area linking Rainbase to the larger market systems of Fish-Man Island and to surface trade vessels. - Coral Bazaar: An open-air market known for crafted goods and rare deep-sea commodities frequented by merchants from the Grand Line. - Submersible Dockyards: Facilities where submersibles and underwater craft—similar in concept to the Sea Train's marine infrastructure—are repaired and outfitted. - Memorial Plaza: A communal site where locals commemorate historical figures such as Fisher Tiger and events relating to the island’s relations with surface humanity. - Thermal Gardens: Areas of unique marine flora nourished by vents; these gardens supply medicinal and culinary ingredients used locally.
