May 21, 2026 is the release date for Yoshi and the Mysterious Book, a Switch 2-exclusive adventure now confirmed to use Unreal Engine 5.
UE5 had surfaced earlier through preload licensing, and Nintendo’s confirmation suggests the company is willing to ship first-party-style Switch 2 software on Epic’s latest engine despite questions about the platform’s UE5 performance.
Mr. E—a talking book that falls onto Yoshi’s island—drives the game’s premise, with players exploring habitats, researching creatures and filling the book’s missing pages.
New mechanics include Yoshi’s Tail Flick alongside tongue, egg, Flutter Jump and Ground Pound abilities, while amiibo scanning grants fortunes and tokens that unlock creature hints.
Bowser Jr. and Kamek also appear to be pursuing their own discovery, adding a broader story thread to a game Nintendo is positioning for both newcomers and longtime Yoshi players.
