The game was announced at Level-5 Vision 2016, along with Yo-kai Daijiten and Yo-kai Watch: Gerapo Rhythm. Not much is known about the port, but it was said that it will have improved graphics, controls that utilize the smartphone's touch screen and network compatibility.
It was initially delayed to 2017 due to them wanting to make some "quality improvements", but got delayed to 2018 again at the end of the year and eventually to 2019 before the release was removed at the end of that year.
- This game and Yo-kai Daijiten has been delayed for the longest amount of time, which has currently nearly four years since it's initial announcement.
