Plot
There was once a boy who can control Yo-kai using a mysterious watch and did his duties maintaining the relationship between two races. His role did not last long as he cannot see Yo-kai when he grows up and the watch the boy once owned was burred within space and time. 30 years later, everyday life resumed and the whole world was peaceful until a strange comet draws near the Earth. An epidemic Yo-kai virus known as Onimaro started affecting people's malevolent intentions and is spreading indefinitely, causing chaos throughout the city. With the end near, only the one chosen by the new Yo-kai Watch can stand up against the upcoming threat and would save both Yo-Kai and humans from certain destruction.

Production
The film was first revealed in the July Issue of Shogakukan's CoroCoro Comic magazine, briefly detailing about the next film and the new Lightside and Shadowside forms of the Yo-Kai featured in the film. The film's official plot and characters were revealed more in the official movie website alongside the staff working in the movie. Akihiro Hino stated the movie is a "completely new horror comedy" and that will be more scarier and funnier compared to the previous films. Aside from the elements, the characters that are revealed in the film will have darker backstories and each Yo-Kai debuting in the film has its own Lightside and Shadowside forms. Level-5 later announced in September that a crossover with the manga series GeGeGe no Kitarō, with veteran voice actor Masako Nozawa revisiting and reprising her role as Kitaro.
