Sandgem Town (Japanese: マサゴタウンMasago Town) is a town in the Sinnohregion. 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 of Dawn or Lucas, depending on the player's gender. The little sister of Dawn or Lucas gives information about mass outbreaks 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.
Professor's assistant's house
Professor Rowan's assistant, Dawn (if the player is male) or Lucas (if the player is female), lives in the house nearest the town's southern exit. Inside, after the player has obtained the National Pokédex and entered the Hall of Fame, the professor's assistant's younger 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:
