On May 21, 2026, Nintendo released "Yoshi and the Mysterious Book," a title exclusive to the Nintendo Switch 2[1]. In this fresh take on the action genre, Yoshi dives into a talking book named Mr. E to investigate its curious creatures, discovering their traits one by one[1][2]. Starting today, in-store demo units and launch campaigns are rolling out as well, setting Yoshi's new adventure in motion all at once[1].
Investigating Creatures Inside the Book
The hero of the game is Yoshi, who heads into the world inside the book at the request of the talking book Mr. E[2]. Curious creatures live within its pages, and Yoshi uses a variety of actions to discover the traits each creature possesses[2]. The creatures are full of personality—some bloom flowers, others blow bubbles—and a trait you uncover can become a hint that leads to the next discovery[2].
The more you investigate and record your findings, the more the book gradually fills in, and new subjects to study—such as creatures that live in the mountains or the sea—keep appearing[2]. Finding one trait can trigger a reaction in another creature, placing a sense of trial-and-error puzzle-solving at the heart of the experience[2].
Rather than clearing stages to reach a goal, the game is built around enjoying observation and discovery themselves, and that is its distinctive character. Game media reviews have also responded favorably to this new style of play centered on investigation and exploration[4]. The title was first revealed at a Nintendo Direct in September 2025, where it was initially announced for a spring 2026 release, and it stands as one of the notable Switch 2 titles[3].
Download Version at 6,980 Yen, With In-Store Demos
The suggested retail price is 6,980 yen (tax included) for the download version and 7,980 yen (tax included) for the packaged version[2]. The title is rated CERO A and supports amiibo, making it easy for the whole family to pick up[2].
To coincide with the launch, the in-store demo units set up at game retailers nationwide can now be used to play a demo of the title[1]. You can actually investigate the flower-like and fluff-like creatures seen in the promotional video, so you can get a feel for the gameplay before buying[1]. An opening movie depicting the encounter between Yoshi and the talking book Mr. E has also been released[1].

Launch Campaigns: Icon Parts, Goods, and More
Several campaigns have also started to mark the launch[1]. Icon parts for the title have been added to the gifts that Nintendo Switch Online members can exchange for Platinum Points, distributed weekly over four weeks from today through June 18[1].
In the smartphone app "Nintendo Store," performing a "GPS check-in" at a Nintendo sales area in a participating store earns you one original sticker[1]. In addition, original goods featuring Yoshi are on sale at Nintendo TOKYO, OSAKA, KYOTO, and FUKUOKA and at the My Nintendo Store, making the world of Yoshi easier to enjoy up close as the game launches[1].
Summary
"Yoshi and the Mysterious Book" is a unique title whose core lies in carefully observing creatures and building up discoveries rather than defeating enemies[2]. Because you can progress at your own pace even if you are not good at action games, it is recommended as a relaxing title both for those who have just picked up a Nintendo Switch 2 and for longtime fans of the Yoshi series. With launch campaigns and in-store demos now available, this is a great time to try the game. Starting with the demo to test out the play that intrigues you, then setting off on the journey of filling in the book, sounds like a fine plan.
