The Yo-kai Watch series feels a lot like Pokémon — but with talking ghosts instead of pocket monsters. It's a collect-all-the-creatures series with both a popular game franchise and an anime that runs alongside it. Previously a 3DS series, the next entry has just been announced in the newest issue of Famitsu (translated by Siliconera), and it's coming to the Switch instead.
Right now all we know is that Yo-kai Watch 4 is coming to Japan some time in 2018, and features characters from the anime including Touma Tsukinami, Natsume Amano, Keisuke Amano, and Akinori Arihoshi.
Speaking about the new game, Level-5 CEO Akihiro Hino suggested that big updates and changes might be coming to Yo-kai Watch 4:
“its content is getting a super high-grade power up, including some things that will surprise everyone.”
All the previous Yo-kai Watch games have received English language releases, so it's probably just a matter of time before we see an announcement.
