The picture quality isn't great on this one, and my apologies for that, but I think you can still read the sign pretty easily. It's the welcome sign for a small store in Karuizawa.
This shop is on the road that leads from Karuizawa shinkansen (bullet train) station out to the Ginza area of this quiet Nagano prefecture mountain town.
I have no idea what the shop sells (it was closed for the winter)...I'll let you take your own guess.
The apostrophe leads me to believe that it could be the owner's (nick)name, but regardless of whence it originated I'm sure that several tourists before me have noticed it while walking by.
