Nocturne Hospital (Japanese: かげむら医院,Kagemura-iin) is an area located in Shopper's Row that appears in the Yo-kai Watch games. It is a four-story abandoned hospital that fell into disuse before the events of the video game, which became a location for Yo-kai.
It is a hospital that has four floors, three of which that can be explored. The first two floors can be accessed via walking on the staircase while the third floor can be visited with a climbing vine from the left side of the hospital's exterior. Another vine can be climbed from the second floor by activating it on the bottom-right corner of the floor.
In Yo-kai Watch 2, going back in time to Old Springdale reveal that the hospital seemed to be operational, but the interior cannot be accessed by the player.
There are some graffiti on the walls of Nocture Hospital that say "UISSU", which is actually based off Whisper's verbal tic "Whissu" (ウィスー！）in the Japanese version of Yo-kai Watch. However, this was strangely kept in the localized versions.
