Pokémon Diamond and Pearl/Sandgem Town

Masago Town houses the laboratory of Professor Rowan, an accomplished professor whose expertise concerns Pokémon, and features the game's first Pokémon Center and Pokémart.

The town was first featured in a promotional video for Diamond and Pearl. The video featured the player as a female walking through the town towards a beach south of Masago. The beach is part of Route 219, and is in close proximity to the town.
