The GeGeGe no Kitaro Nurikabe Scale, to call it by its full name, was inspired by the Nurikabe yokai monster from the long-running Japanese manga comic and animated cartoon "GeGeGe no Kitaro".
What's a nurikabe yokai, you ask? Well, yokai are traditional Japanese monsters from old folk tales, and a nurikabe is a creature that blocks the paths of travelers while staring at them silently with sleepy, hooded eyes. OK, not much of a monster, but back in the days before Cloverfield, Stephen King and Godzilla it was sort of a big deal.
As the nurikabe from GeGeGe no Kitaro sort of looks like a bathroom scale, some bright marketer thought it would be cool to add a pair of dolorous eyes to make a nurikabe on the cheap. Nevermind that a bathroom scale with eyes is sorta weird - just be glad it can't blab about what it's seen.
