Police station

The police station (交番 kōban) is a small, cylindrical building that appears in and. Its sole purpose is to accommodate the Lost and Found, a special service that stores items villagers may have found around the player's town. Players can claim all twenty items without consequences, while the maximum amount of lost items on display is twenty. The arrangement is from the oldest items to the newest items, and the most recent finds will replace the oldest unclaimed items. Items that can be found on display are stationery, clothing and furniture.

Copper stays watch outside of the police station, while Booker stays inside and manages the lost and found corner.

In the original game, the police station displays a town map available for the player's use outside of the building around the small paved path around it. Copper gives out event news, and Booker helps the player with the lost and found section.

In later games
The police station is replaced in and  by the checkpoint, which serves the same purpose as its predecessor and is still staffed by Booker and Copper. In, the police station makes a return as a public works project that can be erected at the cost of 264,000 Bells after being suggested by a villager of any personality. It now has two designs, with the classic police station run by Booker and the modern police station run by Copper.

The mayor must choose between the modern and classic police stations, since it is not possible to have both models at the same time.

Players visiting another town are not able to collect items from shelves in another player's police station.
