During the Anime Expo in July 2019, Level-5 abby replied to a Q&A about a future Western release of Yo-kai Watch 4 and showed the Japanese trailer with English subtitles. Because the game's plot refers to concepts and details that were introduced in the Shadowside and Forever Friends films, which have not yet been given official English-language releases, the marketing company expressed an interest in localizing those films as well. However, as of October 2020, a combination of flagging sales for the series and Level-5's decision to shutter their North American operations, including Level-5 Abby, has led many commentators and journalists to bring in doubt of the possibility of a localization ever happening.
