Cappucci Island (Japanese: カプチ島 Cappucci Island) is an island in the game Detective Pikachu. A ferry service runs once a day between it and Ryme City. Most of Chapter 4 takes place here.
In addition to a small town and the home of John Waals, the island is also home to Lake Cappucci (Japanese: カプチ湖 Lake Cappucci), where a lake festival was traditionally held.
Cappucci comes from cappuccino, a coffee drink of Italian origin.
