During the game, the Construction Site is blocked off with a Rank C Watch Lock and a Yo-kai Watch of that Rank is required to enter. It plays a role in Kyubi The Bully, where Kyubi lures Nate/Katie to the Construction site, hoping to stop the Boss Yo-kai's fire set in Shopper's Row.
Yo-kai Watch 2
The Construction Site appears in Yo-kai Watch 2, but it cannot be entered at night unlike the previous game and has to be finished via a Baffle Board. Later on, the place is turned into the Springdale Sports Club. However, the player can access the third floor via Mirapo, during and after the quest, The Phantom Giant.
There are five yellow chests in the area, one in the far south-west along the narrow walkway, one atop an elevated platform in the central-south, one in the central-west north of the barricade, one in the north-west atop an elevated platform and in the south-east of the room and one in the south-west of the north-eastern room.
The layout of the Construction Site compared to the Springdale Sports Club is drastically different, with the most notable feature not being present are escalators, which was replaced with an elevator.
