There has been numerous Tweets in Japan about sightings of mysterious creature in Nagano, Japan. It's so mysterious you can't see it: an invisible dog.

Is it kind of an urban legend? It doesn't even make sense.

Well, seeing is believing; check out the video below!

You can hear him breath; the lead's moving by itself; that invisible dog is definitely there!

There are all sorts of speculations: like the guy who's walking this dog is a magician, or whether the guy is making the dog noise.

In any case, I'd look twice (or three times) if I see this out of the blue.

I would love to live in a neighborhood where people with such playful soul are around.
