, these are often called "UFO Catchers
", because there's often a small plastic spaceship
or flying saucer
on top of the claw
(This is just hearsay. "UFO Catcher" might be a brand name, a mistranslation, or something misremembered. I don't remember where I read it, anyway.)
A Japanese friend of mine who's there
with his family at least once a year confirms that they do call them that.
