In South Korea, the movie was localized with a September 20, 2018 release.


"There used to be a boy who could control Yo-kai with a mysterious watch. However, he became unable to see Yo-kai when he became an adult. With the boy's duties finished, the watch was buried away in space-time. Then 30 years later, quiet everyday life comes to an end as a fateful day beging with a comet drawing near. The terrible Yo-kai virus Onimaro infects people's malevolent intentions and spreads infinitely. The one chosen by the Yo-kai Watch is the one who can save humanity from its crisis. The bond between humans and Yo-kai may be recovered with the attainment of a new Yo-kai Watch."

The first is Natsume Amano, a 13-year-old Junior High School girl and also the daughter of Nathan Adams, who nearly drowned in a river when she was very young. She remembers "something" saving her from drowning. Second is Touma Tsukinami, a 13-year-old Junior High School boy whose parents are busy with work, so he is always alone and is mysteriously attracts Yo-kai. The last is Akinori Arihoshi, a Shaman-in-training and the oldest of the Arihoshi Siblings, whose family uses Yo-kai in fortune-telling for generations.[6]

Later in September 13, Level-5 officially announced the film to be a crossover with Shigeru Mizuki's GeGeGe no Kitarō manga series, and with the titular characters appearing in the film.[7] The film's second trailer was later released in October of 2017.


Most of the cast from GeGeGe no Kitaro returned to reprise their roles in the film as well as some newcomers. Masako Nozawa will reprised her role again as Kitaro, 9 years after last voicing her character in the 2008 Anime Adaptation of the original Hakaba no Kitarō manga.[8] Other cast that appeared in the film are Yudai Chiba voicing Touma and Mone Kamishiraishi voicing Natsume[6] while Takaya Kuroda and Daisuke Hirakawa voiced Jibanyan and Komasan respectively.[9]

  • This is the first Yo-kai Watch film to be a sequel to the original anime series, and thus it also functions as the pilot of the Shadowside anime series.
  • The film itself marks as the first where Etsuko Kozakura and Aya Endō do not voice Jibanyan and Komasan receptively.
  • This is the first film where Hovernyan doesn't make an appearance.
  • Invader Mode Usapyonm Dame Dedtime, Narwail, Komajiro, and Noway all appear in the credits.
  • Because of how Yo-kai Watch Forever Friends relates to this movie, it's most likely to think that Forever Friends served as the prologue to this movie, with the former, setting the elements of Yo-kai Watch Shadowside into place, and the latter being what happened 30 years afterward.
