A Yo-kai Ark (Japanese: 妖怪アーク Yōkai Āku) is a small, key-shaped item used to summon Yo-kai from the Yo-kai Watch Elder. They are said to be the successor of Yo-kai Medals, featuring Lightside and Shadowside Yo-kai on both sides.

Rare versions with different colors also exist. The levels of rarity that range from common, to extremely rare, are Normal, Rare, Extreme Rare, Super Extreme Rare, and Ultimate Rare.[1]

Most of the Normal Arks have a clear color and a regular holo foil, while Rare Arks have a clear color and a glittering holo foil, and Extreme Rare Arks have the colors of their tribes, as well as glittering holo foil.

There are also Shining Arks that are equal to Super Extreme Rare ones, and Gold Arks that are equal to Extreme Rare ones.

In the Yo-kai Ark 0 pack, there also are Yo-kai Arks that have a Lightside form, but also a Godside form, for use with the Yo-kai Watch Elder Jin parts, that can be found in the DX Yo-kai Watch Elder Zero & Jin Power-up Kit. These are of a white base colour, with a rainbow holo for the Godside forms.

Yo-kai Arks represent the feelings that connect Yo-kai and humans. Just like Yo-kai Medals, they are given to select people once they fulfill a specific Yo-kai's needs.

Yo-kai can be summoned via the Yo-kai Watch Elder by putting the Ark into the keyhole, and saying the summoning chant while the Yo-kai appears in sight.

It was originally thought that the Arks were successors to the medals, however, due to their inclusion in Forever Friends and Yo-kai Watch!, they may have existed in the past as well.
