The Yokai Watch

The Yokai Watch is a very important item in the game that the main character uses to see Yo-kai in the real world. It has 4 different models

Overview
The Yo-kai Watch is an unique piece of technology which helps humans to uncover and communicate with Yo-kai, a feat normally impossible without the use of this device. Conversely, the Yo-kai watch is useful for Yo-kai to communicate with humans.

The real power of the Yo-kai Watch, however is the ability granted to the use to summon Yo-kai he/she has previously befriended by inserting their respective Yo-kai Medals into its gap. Each of the twelve primary tribes of Yo-kai have their own summoning song, as well as their surge of light sporting the respective color of the backs of their medals. It should be noted that a medal inserted upside down (or wrong side up) will not trigger the summon; the original Watch model had it where it would make the leader of the Nosirs say: "Ah ah ah!" in a scolding manner.
