A sandy town that is located right next to a beach. It is redolent with the salty scent of the sea. Prof. Rowan's lab is the town's landmark. He conducts his studies on Pokémon here.
Sandgem Town (Japanese: マサゴタウンMasago Town) is a location in the region of Sinnoh, the featured area in the Generation IV games, Pokémon Diamond and Pearl. The town notably has sandy terrain to the south, the beginnings of Sandgem Beach. The beach, part of Route 219, is in close proximity to the town itself.
Professor Rowan's laboratory is located here. It is also the hometown for Dawn or Lucas, depending on the player's gender. The little sister of Dawn or Lucas gives information about swarms she sees on television. It is the first location in Sinnoh where Poké Balls are able to be purchased. The town smells of the salty scent of the sea.
The Lab lies right next to the western entrance into Sandgem Town. Professor Rowan works here along with two assistants, one of whom is the father of Dawn/Lucas. It is here that the Professor gives the player their Pokédex.

As the player's pseudo-rival, Dawn (if the player character is male) or Lucas (if the player character is female) will live in the house nearest to the southern entrance. Inside, after receiving the National Pokédex and defeating the Elite Four, their sister will inform the player of any Mass Outbreaks.
Sandgem's Pokémon Center is located right next to the Pokémon Research Lab, and is the first Pokémon Center the player will encounter on their journey. It provides an essential place for Trainers from the neighboring routes to stop and rest. A sign outside reads:
