Lacunosa Town (Japanese: カゴメタウンKagome Town) is a town in the northeastern area of the Unova region. To the west of Lacunosa Town is Route 12 and to the east is Route 13. To the north-east of Lacunosa Town lies the Giant Chasm, which is a location that has affected the residents of the town greatly for many years.
A long time ago, it is said that a large meteor came from the sky containing a terrifying monster. It was said that at night the monster would appear in the town along with the cold winds and take away humans and Pokémon to eat them. Eventually, the residents of the town surrounded Lacunosa Town in a wall to keep the monster out and a rule was then set on the town that forbade anyone from leaving at night and encouraged people to stay in their homes. Even though Lacunosa residents claim to no longer believe this old story, they still stay inside of their houses at night and the walls remain standing to this day.
The girl on the secondBW/firstB2W2 floor can tell the player what Pokémon were on their team at the time they earned a particular GymBadge if the player agrees to show her that Badge.
Executive's house
The house on the northeastern part of the town's walls is home to a businessman, though due to business trips during the week, he only appears on SundayBW nights. He gives the player one Berry from a range of Berries, some of which are not commonly found in Unova.
Lacunosa Town is the only town in the known Pokémon world whose citizens' schedule changes dramatically based on the time of day.
In Black 2 and White 2, Professor Juniper directly mentions the possible origin of the name "Lacunosa," deriving the origin from lacunosus and describing the cloud type as a formation that resembles "a net or a fence," while relating that origin to the reason for the walls around Lacunosa Town, designed to keep Kyurem away.
