Let the good times roll!
I can't find the artist's name on there. Well, to be perfectly clear, "Kawasaki" can actually be a surname as well as a location name (and a motorcycle name), so there is a chance that Kawasaki is actually the artist's name instead of the location.
BUT... given that the scarf clearly says Tōkaidō in Japanese, and since it shows a river-crossing with Mt. Fuji in the background, I'm sure that the Kawasaki written on the scarf is a reference to the place (and is not the name of the artist).
