If the Yamato tricycle isn't what you're looking for, don't count Japan out. Try this one for size - a blast from the past from 2006:
Watch out, JAPAN AT ITS BEST! I might have some difficulties explaining this one to you… Bandai is releasing the “Neko Nyanbou” in Japan sometime in April. So what is it? Well, these are fake cat paws with claws that can be controlled by a small switch hidden in the “handle”. Why on earth would you use these? To scratch your back, to scare a colleague or just as an extension of your arm… the drawings below will explain what I mean. So yes, they are crazy, but that’s exactly what we love about them!
