After selling millions and being a cultural phenomenon in Japan, YO-KAI WATCH is coming to the United States for the Nintendo 3DS family of systems. The YO-KAI WATCH game is about hundreds of sometimes cute, sometimes spooky, and usually mischievous Yo-kai that inhabit our world. Yo-kai are not ghosts, monsters or creatures. Yo-kai are, quite simply, Yo-kai. They cannot be seen by the human eye, but they are everywhere.
