Bandai Team Shohoku (19??, LCD, Watch Batteries, Model# 42506)
I really don't know what this is, but from the information on the bottom of the front of the box (where it says 'Charamovie') it sounds like it's just a little toy that displays an animation of some characters (i.e., no interaction, it just plays a sort of video clip). Not sure though, and I'm not sure if there are others in the series.
