"Mofy" sweets are currently on display at Cubic Plaza in Shin-Yokohama and the Totti Candy Factory Harajuku store in Tokyo through January.
Both stores will sell a line of cotton candy based on the titular cotton rabbit, while the Harajuku location will see both cotton candy and cake pops.
The launch is supported by a Twitter competition that invites fans to tweet for a chance to win one of four cotton candy models.
