Plot
Jibanyan, Komasan, and USApyon find a mysterious book called Youkai Sangokushi. When they open it, they are teleported into the book as characters within the narrative. Trapped by the book's powers and forced to act as famous Three Kingdom figures, they must unify the divided Sakura Country to find their way back home.

The player can choose Jibanyan Liu Bei, Komasan Sun Ce, or USApyon Zhongda to be their protagonist.

Gameplay
Characters explore the world map from an overhead view. Areas have a night and day cycle, and wandering yo-kai signify potential battles. Players can check the overall strengths of their party and their opponent's party before engaging in battle. If there are ally yo-kai nearby, the player's team can reach a maximum of six members.

Battles take place on a 3D isometric rotatable grid. Characters can attack normally or unleash their unique "Yo-jutsu" (magic). Yo-jutsu has limited uses per turn but have a higher chance of hitting groups.
 * If two friendly yo-kai are adjacent to one another, they can "Attach" themselves together. These gestures grants various beneficial effects such as stunning enemies or boosting an ally's attack power.
 * The Special Technique gauge in the middle of the battle menu will gradually fill up as the battle progresses. Once it hits maximum, it can be tapped to unleash a powerful attack.

There are over 400 different yo-kai. They can be summoned randomly through the Yo-kai gatcha. There are many rare yo-kai that can only be obtained through the machine.

If the player owns collectible medals, they can upgrade their yo-kai to become stronger legendary warriors. Owning the other Yo-Kai Watch Nintendo 3DS titles (both versions of Busters and every version of Yo-Kai Watch 2) grants players the privilege to use unique yo-kai.
