What object lets a person summon befriended Yo-kai in Yo-kai Watch?

A Yo-kai Medal lets a person summon a befriended Yo-kai in Yo-kai Watch. After the player forms a friendship with a Yo-kai, that Yo-kai provides a medal representing the bond and allowing it to be called into action.

The medal works alongside the titular Yo-kai Watch. The Watch allows its user to see hidden Yo-kai and interact with them, while the medal functions as the summoning token. In the games, summoned Yo-kai can fight other Yo-kai, help solve problems, or assist with everyday situations.

Summon Coin and Yo-kai Card are plausible-sounding distractors, but they are not the standard answer for the franchise’s core summoning mechanic. The term also appears in the physical toy line, where Yo-kai Medals can interact with compatible Watch toys. Specific Watch models and later media introduce additional devices or collectible formats, but the basic object associated with a befriended Yo-kai remains the Yo-kai Medal.
