The Orange Archipelago (Japanese: オレンジ諸島Orange Archipelago), more commonly known as the Orange Islands, is a large chain of tropical islands shown in the anime that is located south of the Kantoregion. Pokémon Trainers come here to participate in the Orange League, but its tropical climate also attracts many tourists. One effect of the climate is the presence of alternately colored Pokémon.
Most of the scattered islands in the archipelago are named after types of oranges or other various citrus, and many are deserted. The Officer Jennys and Nurse Joys of the archipelago dress in slightly different attire than those of the other regions. Some also appear to have tans.
Only four Orange League Badges are required to participate in championship competition, held on Pummelo Island. Unlike Gyms in other regions, the Orange League requires participants to complete challenges for the leaders of the Orange League, the Orange Crew.
Compared to the Gym Leaders of the other regions Ash has visited, the challenges set by the Orange Crew are not restricted to a building serving as the Gym, with Danny's tasks involving a mountain while Cissy and Rudy had a portion of their challenges involving the ocean. Only Luana hosted hers in a Gym arena although this was an extension to her hotel.
