Nimbasa Town (Japanese: ライモンタウン Raimon Town) is an anime-exclusive town in the Unova region located southeast of Nimbasa City. Much like Nimbasa City, the town has a theme-park style to it and features a ferris wheel, although Nimbasa Town has been around longer. It is known to have a Battle Club built as a stadium that hosts the Club Battle Tournament.
Ash, Iris, Cilan, and Luke arrived in Nimbasa Town in Reunion Battles In Nimbasa! to take part in the Club Battle. Ash mistook the town for Nimbasa City at first when he asked where the Gym was. Luke then explained that they're two different places. After Bianca catched up with them, the four of them went to the stadium and signed up for the Club Battle. There they met up with Burgundy, Stephan, Georgia, and Trip who were also taking part in the tournament.
