From Bulbapedia, the community-driven Pokémon encyclopedia.
Torom Island (Japanese: ムトロ島 Mutoro Island) is the fifth island Ash, Iris, and Cilan visited during their travels through the Decolore Islands.
The island features transmission towers, where three Rotom reside. Ash and his friends met up with Professor Oak here, who came to the island to catch a Rotom for his thesis. With their help, Professor Oak was able to capture one after defeating Team Rocket.
